服务器优化

第一步：修改php-fpm运行方式为 socket

打开/Data/apps/php7/etc/php-fpm.d/www.conf文件，并将listen = 127.0.0.1:9000修改为listen = /tmp/php-cgi.sock
Socket是使用unix domain socket连接套接字/dev/shm/php-cgi.sock（很多教程使用路径/tmp，而路径/dev/shm是个tmpfs，速度比磁盘快得多）listen = /dev/shm/php-cgi.sock

第二步：修改nginx配置文件

location ~ [^/]\.php(/|$) {
        #fastcgi_pass 127.0.0.1:9000;
        fastcgi_pass unix:/dev/shm/php-cgi.sock;
        fastcgi_index index.php;
        include fastcgi.conf;
}   

第三步：重启fpm和nginx

==================================================================

测试php-fpm配置

/usr/local/php/sbin/php-fpm -t
/usr/local/php/sbin/php-fpm -c /chenamu/server/php/etc/php.ini -y /chenamu/server/php/etc/php-fpm.conf -t

启动php-fpm

/usr/local/php/sbin/php-fpm
/usr/local/php/sbin/php-fpm -c /chenamu/server/php/etc/php.ini -y /chenamu/server/php/etc/php-fpm.d/www.conf.1

关闭php-fpm

kill -INT cat /usr/local/php/var/run/php-fpm.pid

重启php-fpm

kill -USR2 cat /usr/local/php/var/run/php-fpm.pid
/chenamu/server/php/etc/php-fpm.d/www.conf.1
/chenamu/server/php/etc/php-fpm.d/www.conf

=================================================

加强优化

第一步：修改php-fpm运行方式为 socket

第二步：cp多个www.conf，并修改listen = /tmp/php-cgi.sock.1

第三步：修改nginx的配置文件

upstream phpbackend {
    server unix:/tmp/php-cgi.sock weight=100 max_fails=10 fail_timeout=30;
    server unix:/tmp/php-cgi.sock.1 weight=100 max_fails=10 fail_timeout=30;
}

server {
    server_name 127.0.0.1;
    listen 444; 
    ssl on;
    ssl_certificate /prefix/nginx/conf/33iq.crt;
    ssl_certificate_key /prefix/nginx/conf/33iq_nopass.key;
    ssl_protocols SSLv2 TLSv1;
    ssl_ciphers ECDHE-RSA-AES256-SHA384:AES256-SHA256:HIGH:!MD5:!aNULL:!eNULL:!NULL:!DH:!EDH:!AESGCM;
    client_max_body_size 512M;
    add_header X-Frame-Options SAMEORIGIN;
    charset utf-8;  
    root   /prefix/admin; 
        index  index.html index.htm index.php;
        location / {
        index  index.htm index.html index.php;  
            if (!-e $request_filename){
                rewrite ^(.*)$ /index.php last;
            }
    }
    
    location ~ \.php(.*)$ {
        #fastcgi_pass    127.0.0.1:9000;
        fastcgi_pass    phpbackend;
        #fastcgi_pass    unix:/tmp/php-cgi.sock;
        fastcgi_index  index.php;
        # fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        fastcgi_param  PATH_INFO  $fastcgi_path_info;
        # fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
        include        fastcgi_params;
    }
 }```
#### 第四步：重启nginx和php-fpm（php-fpm启动时指定相应的配置文件）
