一、配置网络
查看网卡：
ifconfig -a
直接改eth0吧，如下
输入命令：
vi /etc/sysconfig/network-scripts/ifcfg-eth0
我的配置如下：
DEVICE="eth0" BOOTPROTO=none NM_CONTROLLED="yes" //修改为yes后无需要重启网卡立即生效 ONBOOT=yes TYPE="Ethernet" UUID="b400000d-9a8c-4000-ac73-9ce00c86c000" HWADDR=00:00:00:00:00:00 IPADDR=192.168.1.202 //你的IP PREFIX=24 //子网掩码 GATEWAY=192.168.1.254 //网关 DNS1=8.8.4.4 //DNS DNS2=8.8.8.8 DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="System eth0"
这里我还是重启了网卡：
service network restart
二、CentOS6.3配置yum源
备份并替换系统的repo文件
mv /etc/yum.repos.d/CentOS-Base.repo CentOS-Base.repo.bak
vi /etc/yum.repos.d/CentOS-Base.repo
# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-$releasever - Base - 163.com baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #released updates [updates] name=CentOS-$releasever - Updates - 163.com baseurl=http://mirrors.163.com/centos/$releasever/updates/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras - 163.com baseurl=http://mirrors.163.com/centos/$releasever/extras/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus - 163.com baseurl=http://mirrors.163.com/centos/$releasever/centosplus/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #contrib - packages by Centos Users [contrib] name=CentOS-$releasever - Contrib - 163.com baseurl=http://mirrors.163.com/centos/$releasever/contrib/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
执行yum源更新
yum clean all
yum makecache
yum update
注：
yum 是 Fedora RHEL Centos SUSE等linux 发行版的 软件包管理工具
通过 执行 man yum 查看yum的帮助信息 可以知道
yum makecache 是 将服务器上的软件包信息 现在本地缓存,以提高 搜索 安装软件的速度
yum 主要的一下命令如下:
yum search 软件包 搜索软件包
yum install 软件包 安装软件包
yum remove 软件包
yum update 更新系统
安装centos常用的软件包及工具 常见压缩工具
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel patch openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers
cmake编译器 Mysql5.5需要Cmake安装
yum -y install cmake make
三、下载【适用CentOS、RedHat及其它Linux操作系统】下载程序源码包：
mkdir -p /Downloads cd /Downloads wget http://nginx.org/download/nginx-1.2.6.tar.gz wget http://cn2.php.net/distributions/php-5.2.17.tar.gz wget http://php-fpm.org/downloads/php-5.2.17-fpm-0.5.14.diff.gz wget http://cdn.mysql.com/Downloads/MySQL-5.5/mysql-5.5.29.tar.gz wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz wget http://superb-dca3.dl.sourceforge.net/project/mcrypt/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz wget http://hivelocity.dl.sourceforge.net/project/mcrypt/MCrypt/2.6.8/mcrypt-2.6.8.tar.gz wget http://pecl.php.net/get/memcache-2.2.7.tgz wget http://nchc.dl.sourceforge.net/project/mhash/mhash/0.9.9.9/mhash-0.9.9.9.tar.gz wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.32.tar.gz wget http://blog.s135.com/soft/linux/nginx_php/eaccelerator/eaccelerator-0.9.6.1.tar.bz2 wget http://pecl.php.net/get/PDO_MYSQL-1.0.2.tgz wget http://servingzone.com/mirrors/ImageMagick/ImageMagick-6.8.1-10.tar.gz wget http://pecl.php.net/get/imagick-3.0.1.tgz
四、安装PHP 5.2.14（FastCGI模式）
tar zxvf libiconv-1.14.tar.gz cd libiconv-1.14/ ./configure --prefix=/usr/local make
make install cd ../
tar zxvf libmcrypt-2.5.8.tar.gz cd libmcrypt-2.5.8/ ./configure make make install /sbin/ldconfig cd libltdl/ ./configure --enable-ltdl-install make make install cd ../../
tar zxvf mhash-0.9.9.9.tar.gz cd mhash-0.9.9.9/ ./configure make make install cd ../

tar zxvf mcrypt-2.6.8.tar.gz cd mcrypt-2.6.8/ /sbin/ldconfig ./configure make make install cd ../
编译安装MySQL 5.5.3-m3
/usr/sbin/groupadd mysql /usr/sbin/useradd -g mysql mysql tar zxvf mysql-5.5.3-m3.tar.gz cd mysql-5.5.3-m3/ ./configure --prefix=/usr/local/webserver/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=partition,innobase,myisammrg make && make install chmod +w /usr/local/webserver/mysql chown -R mysql:mysql /usr/local/webserver/mysql cd ../
附：以下为附加步骤，如果你想在这台服务器上运行MySQL数据库，则执行以下几步。如果你只是希望让PHP支持MySQL扩展库，能够连接其他服务器上的MySQL数据库，那么，以下两步无需执行。
①、创建MySQL数据库存放目录
mkdir -p /data0/mysql/3306/data/ mkdir -p /data0/mysql/3306/binlog/ mkdir -p /data0/mysql/3306/relaylog/ chown -R mysql:mysql /data0/mysql/
②、以mysql用户帐号的身份建立数据表：
/usr/local/webserver/mysql/bin/mysql_install_db --basedir=/usr/local/webserver/mysql --datadir=/data0/mysql/3306/data --user=mysql
③、创建my.cnf配置文件：
vi /data0/mysql/3306/my.cnf
输入以下内容：
引用

innodb_additional_mem_pool_size = 16M innodb_buffer_pool_size = 512M innodb_data_file_path = ibdata1:256M:autoextend innodb_file_io_threads = 4 innodb_thread_concurrency = 8 innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 16M innodb_log_file_size = 128M innodb_log_files_in_group = 3 innodb_max_dirty_pages_pct = 90 innodb_lock_wait_timeout = 120 innodb_file_per_table = 0
#log-slow-queries = /data0/mysql/3306/slow.log #long_query_time = 10
[mysqldump] quick max_allowed_packet = 32M
④、创建管理MySQL数据库的shell脚本：
vi /data0/mysql/3306/mysql
输入以下内容（这里的用户名admin和密码12345678接下来的步骤会创建）：
#!/bin/sh
mysql_port=3306 mysql_username="admin" mysql_password="12345678"
function_start_mysql() { printf "Starting MySQL...\n" /bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/data0/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null & }
function_stop_mysql() { printf "Stoping MySQL...\n" /usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown }
function_restart_mysql() { printf "Restarting MySQL...\n" function_stop_mysql sleep 5 function_start_mysql }
function_kill_mysql() { kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}') kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}') }
if [ "$1" = "start" ]; then function_start_mysql elif [ "$1" = "stop" ]; then function_stop_mysql elif [ "$1" = "restart" ]; then function_restart_mysql elif [ "$1" = "kill" ]; then function_kill_mysql else printf "Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}\n" fi
mysql_port=3306 mysql_username="admin" mysql_password="12345678"
function_start_mysql() { printf "Starting MySQL...\n" /bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/data0/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null & }
function_stop_mysql() { printf "Stoping MySQL...\n" /usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown }
function_restart_mysql() { printf "Restarting MySQL...\n" function_stop_mysql sleep 5 function_start_mysql }
function_kill_mysql() { kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}') kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}') }
if [ "$1" = "start" ]; then function_start_mysql elif [ "$1" = "stop" ]; then function_stop_mysql elif [ "$1" = "restart" ]; then function_restart_mysql elif [ "$1" = "kill" ]; then function_kill_mysql else printf "Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}\n" fi
⑤、赋予shell脚本可执行权限：
chmod +x /data0/mysql/3306/mysql
⑥、启动MySQL：
/data0/mysql/3306/mysql start
⑦、通过命令行登录管理MySQL服务器（提示输入密码时直接回车）：
/usr/local/webserver/mysql/bin/mysql -u root -p -S /tmp/mysql.sock
⑧、输入以下SQL语句，创建一个具有root权限的用户（admin）和密码（12345678）：
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678';
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY '12345678';
⑨、（可选）停止MySQL：
/data0/mysql/3306/mysql stop
编译安装PHP（FastCGI模式）
tar zxvf php-5.2.17.tar.gz gzip -cd php-5.2.17-fpm-0.5.14.diff.gz | patch -d php-5.2.17 -p1 cd php-5.2.17/ ./configure --prefix=/usr/local/webserver/php --with-config-file-path=/usr/local/webserver/php/etc --with- mysql=/usr/local/webserver/mysql --with-mysqli=/usr/local/webserver/mysql/bin/mysql_config --with-iconv- dir=/usr/local --with-freetype-dir --with-jpeg-dir=/usr/lib64 --with-png-dir=/usr/lib64 --with-zlib -- with-libxml-dir=/usr/lib64 --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable- bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers -- enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --with-bz2 --enable-zip --enable-wddx --enable-soap 指定png目录 "./configure" \ "--prefix=/usr/local/php5" \ "--enable-force-cgi-redirect" \ "--enable-fastcgi" \ "--with-bz2" \ "--with-config-file-path=/usr/local/etc" \ "--with-config-file-scan-dir=/usr/local/etc/php.d" \ "--with-curl=/usr/local/lib" \ "--with-gd" \ "--with-gettext" \ "--with-jpeg-dir=/usr/local/lib" \ "--with-freetype-dir=/usr/local/lib" \ "--with-kerberos" \ "--with-mcrypt" \ "--with-mhash" \ "--with-mime-magic" \ "--with-mysql" \ "--with-mysqli" \ "--with-pcre-regex=/usr" \ "--with-pdo-mysql=shared" \ "--with-pdo-sqlite=shared" \ "--with-pear=/usr/local/lib/php" \ "--with-png-dir=/usr/local/lib" \ "--with-pspell" \ "--with-sqlite=shared" \ "--with-tidy" \ "--with-ttf" \ "--with-xmlrpc" \ "--with-xsl" \ "--with-zlib" \ "--with-zlib-dir=/usr/local/lib" \ "--with-openssl" \ "--with-iconv" \ "--with-libdir=lib64" \ "--enable-bcmath" \ "--enable-calendar" \ "--enable-exif" \ "--enable-ftp" \ "--enable-gd-native-ttf" \ "--enable-libxml" \ "--enable-magic-quotes" \ "--enable-soap" \ "--enable-sockets" \ "--enable-mbstring" \ "--enable-zip" \ "--enable-wddx" make ZEND_EXTRA_LIBS='-liconv' make install cp php.ini-dist /usr/local/webserver/php/etc/php.ini cd ../
编译安装PHP5扩展模块
tar zxvf memcache-2.2.7.tgz cd memcache-2.2.7/ /usr/local/webserver/php/bin/phpize ./configure --with-php-config=/usr/local/webserver/php/bin/php-config make make install cd ../ tar jxvf eaccelerator-0.9.6.1.tar.bz2 cd eaccelerator-0.9.6.1/ /usr/local/webserver/php/bin/phpize ./configure --enable-eaccelerator=shared --with-php-config=/usr/local/webserver/php/bin/php-config make make install cd ../ tar zxvf PDO_MYSQL-1.0.2.tgz cd PDO_MYSQL-1.0.2/ /usr/local/webserver/php/bin/phpize ./configure --with-php-config=/usr/local/webserver/php/bin/php-config --with-pdo-mysql=/usr/local/webserver/mysql make make install cd ../
yum -y install perl-CPAN tar zxvf ImageMagick-6.8.1-10.tar.gz cd ImageMagick-6.8.1-10/ ./configure --prefix=/usr/local/webserver/ImageMagick
make make install cd ../ tar zxvf imagick-3.0.1.tgz cd imagick-3.0.1/ /usr/local/webserver/php/bin/phpize
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
./configure --with-php-config=/usr/local/webserver/php/bin/php-config --with-imagick=/usr/local/webserver/ImageMagick
make
make install cd ../
5、修改php.ini文件
手工修改：
查找
vi /usr/local/webserver/php/etc/php.ini
中的
extension_dir = "./"
修改为
extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"
并在此行后增加以下几行，然后保存：
extension = "memcache.so"
extension = "pdo_mysql.so"
extension = "imagick.so"
再查找output_buffering = Off
修改为output_buffering = On
再查找; cgi.fix_pathinfo=0
修改为cgi.fix_pathinfo=0，防止Nginx文件类型错误解析漏洞。
6、配置eAccelerator加速PHP：
mkdir -p /usr/local/webserver/eaccelerator_cache
vi /usr/local/webserver/php/etc/php.ini
按shift+g键跳到配置文件的最末尾，加上以下配置信息：
[eaccelerator] zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so" eaccelerator.shm_size="64" eaccelerator.cache_dir="/usr/local/webserver/eaccelerator_cache" eaccelerator.enable="1" eaccelerator.optimizer="1" eaccelerator.check_mtime="1" eaccelerator.debug="0" eaccelerator.filter="" eaccelerator.shm_max="0" eaccelerator.shm_ttl="3600" eaccelerator.shm_prune_period="3600" eaccelerator.shm_only="0" eaccelerator.compress="1" eaccelerator.compress_level="9"
7、创建www用户和组，虚拟主机使用的目录：
/usr/sbin/groupadd www /usr/sbin/useradd -g www www mkdir -p /www/djws chmod +w /www/djws
chown -R www:www /www/djws
8、创建php-fpm配置文件（php-fpm是为PHP打的一个FastCGI管理补丁，可以平滑变更php.ini配置而无需重启php-cgi）：
在/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件：
rm -f /usr/local/webserver/php/etc/php-fpm.conf
vi /usr/local/webserver/php/etc/php-fpm.conf
输入以下内容（如果您安装 Nginx + PHP 用于程序调试，请将以下的
"1.0" ?>All relative paths in this config are relative to php's install prefix "global_options"> Pid file "pid_file">/usr/local/webserver/php/logs/php-fpm.pid Error log file"error_log">/usr/local/webserver/php/logs/php-fpm.log Log level"log_level">notice When this amount of php processes exited with SIGSEGV or SIGBUS ..."emergency_restart_threshold">10 ... in a less than this interval of time, a graceful restart will be initiated.

9、启动php-cgi进程，监听127.0.0.1的9000端口，进程数为128（如果服务器内存小于3GB，可以只开启64个进程），用户为www：
ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm start
注：/usr/local/webserver/php/sbin/php-fpm还有其他参数，包括：start|stop|quit|restart|reload|logrotate，修改php.ini后不重启php-cgi，重新加载配置文件使用reload。
三、安装Nginx 0.8.46
1、安装Nginx所需的pcre库：
tar zxvf pcre-8.32.tar.gz cd pcre-8.32/ ./configure make && make install cd ../
2、安装Nginx
tar zxvf nginx-1.2.6.tar.gz cd nginx-1.2.6/ ./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module make && make install cd ../
3、创建Nginx日志目录
mkdir -p /data/nginx/logs chmod +w /data/nginx/logs chown -R www:www /data/nginx/logs
4、创建Nginx配置文件
①、在/usr/local/webserver/nginx/conf/目录中创建nginx.conf文件：
rm -f /usr/local/webserver/nginx/conf/nginx.conf
vi /usr/local/webserver/nginx/conf/nginx.conf
输入以下内容：
user www www; worker_processes 8; error_log /data/nginx/logs/nginx_error.log crit; pid /usr/local/webserver/nginx/logs/nginx.pid; #Specifies the value for maximum file descriptors that can be opened by this process. worker_rlimit_nofile 65535; events { use epoll; worker_connections 65535; } http { include mime.types; default_type application/octet-stream; #charset gb2312; server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 8m; sendfile on; tcp_nopush on; keepalive_timeout 60; tcp_nodelay on; fastcgi_connect_timeout 300; fastcgi_send_timeout 300; fastcgi_read_timeout 300; fastcgi_buffer_size 64k; fastcgi_buffers 4 64k; fastcgi_busy_buffers_size 128k; fastcgi_temp_file_write_size 128k; gzip on; gzip_min_length 1k; gzip_buffers 4 16k; gzip_http_version 1.0; gzip_comp_level 2; gzip_types text/plain application/x-javascript text/css application/xml; gzip_vary on; #limit_zone crawler $binary_remote_addr 10m;
log_format access '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
access_log /data/nginx/logs/access.log access;
server { listen 80; server_name www.165au.com; index index.html index.htm index.php; root /www/root; #limit_conn crawler 20; location ~ .*\.(php|php5)?$ { #fastcgi_pass unix:/tmp/php-cgi.sock; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; include fcgi.conf; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*\.(js|css)?$ { expires 1h; }
location /status {
stub_status on;
access_log off;
auth_basic "Nginx Status"; #密码验证的提示语
auth_basic_user_file /usr/local/webserver/nginx/conf/htpasswd; #用户名和密码存放的文件
}
} }
关于那个文件的生成，请参见工具htpasswd的使用。
vi /usr/local/webserver/nginx/conf/htpasswd
文件中的数据格式是：
user:cryt-password
#用户名称：加密后的密码
这里给大家提供一些在线加密的网站：
http://www.htaccesstools.com/htpasswd-generator/
②、在/usr/local/webserver/nginx/conf/目录中创建fcgi.conf文件：
vi /usr/local/webserver/nginx/conf/fcgi.conf
输入以下内容：
fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; # PHP only, required if PHP was built with --enable-force-cgi-redirect fastcgi_param REDIRECT_STATUS 200;
5、启动Nginx
ulimit -SHn 65535
/usr/local/webserver/nginx/sbin/nginx
启动nginx时，提示：error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory
解决方法：
32位系统 [root@sever lib]# ln -s /usr/local/lib/libpcre.so.1 /lib
64位系统 [root@sever lib]# ln -s /usr/local/lib/libpcre.so.1 /lib64
四、配置开机自动启动Nginx + PHP
vi /etc/rc.local
在末尾增加以下内容：
ulimit -SHn 65535 /usr/local/webserver/php/sbin/php-fpm start /usr/local/webserver/nginx/sbin/nginx
五、优化Linux内核参数
vi /etc/sysctl.conf
在末尾增加以下内容：
# Add net.ipv4.tcp_max_syn_backlog = 65536 net.core.netdev_max_backlog = 32768 net.core.somaxconn = 32768 net.core.wmem_default = 8388608 net.core.rmem_default = 8388608 net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 net.ipv4.tcp_timestamps = 0 net.ipv4.tcp_synack_retries = 2 net.ipv4.tcp_syn_retries = 2 net.ipv4.tcp_tw_recycle = 1 #net.ipv4.tcp_tw_len = 1 net.ipv4.tcp_tw_reuse = 1 net.ipv4.tcp_mem = 94500000 915000000 927000000 net.ipv4.tcp_max_orphans = 3276800 #net.ipv4.tcp_fin_timeout = 30 #net.ipv4.tcp_keepalive_time = 120 net.ipv4.ip_local_port_range = 1024 65535
使配置立即生效：
/sbin/sysctl -p
配置status
配置文件中加上
