CentOS编译安装php7.2
升级或安装PHP依赖：
安装php依赖包，避免编译安装php7时报错
更新epel：
yum install epel-release -y
yum update安装php依赖组件（包含Nginx依赖）：
yum -y install wget vim pcre pcre-devel openssl openssl-devel libicu-devel 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 ncurses ncurses-devel curl curl-devel krb5-devel libidn libidn-devel openldap openldap-devel nss_ldap jemalloc-devel cmake boost-devel bison automake libevent libevent-devel gd gd-devel libtool* libmcrypt libmcrypt-devel mcrypt mhash libxslt libxslt-devel readline readline-devel gmp gmp-devel libcurl libcurl-devel openjpeg-devel创建www用户给php-fpm，下载php安装包解压：
useradd www -M -s /sbin/nologin
wget http://am1.php.net/distributions/php-7.2.1.tar.gz
tar xvf php-7.2.1.tar.gz -C /usr/local/src
cd !$设置变量：
cp -frp /usr/lib64/libldap* /usr/lib/检测、编译、安装以及遇到的问题：
./configure --prefix=/usr/local/php \
--with-config-file-path=/usr/local/php/etc \
--enable-fpm \
--with-fpm-user=www \
--with-fpm-group=www \

--with-gettext \
--disable-fileinfo \
--enable-opcache \
--with-pear \
--enable-maintainer-zts \
--with-ldap=shared \
--without-gdbm若无报错执行下一步安装，如果编译过程中出现错误，根据报错安装依赖包，通常不会出现这种问题。
以下内容在此版本无效：
--enable-gd-native-ttf
--with-libmbfl
--with-mcrypt
--enable-gd-jis-conv
注意：–enable-gd-jis-conv 此参数会导致Zabbix中文字符乱码，建议取消。
如果遇到错误：configure: error: Please reinstall the libzip distribution，则需要下载或升级libzip
升级libzip：
[root@localhost ~]# wget https://libzip.org/download/libzip-1.5.2.tar.gz
[root@localhost ~]# tar -zxf libzip-1.5.2.tar.gz
[root@localhost ~]# cd libzip-1.5.2
[root@localhost ~]# mkdir build
[root@localhost ~]# cd build
[root@localhost ~]# cmake ..
[root@localhost ~]# make
[root@localhost ~]# make test
[root@localhost ~]# make install安装libzip需要cmake大于3.0，如果提示cmake版本低，请升级cmake
下载以及安装cmake：
#下载cmake包
wget https://cmake.org/files/v3.6/cmake-3.6.2.tar.gz
#解压cmake包
tar xvf cmake-3.6.2.tar.gz && cd cmake-3.6.2/
#安装
./bootstrap
gmake
gmake install如果遇到：checking size of off_t... 0 configure: error: off_t undefined; check your library configuration
vim /etc/ld.so.conf
#添加如下几行
/usr/local/lib64
/usr/local/lib
/usr/lib
/usr/lib64
#保存退出
:wq
ldconfig -v #生效ldconfig或者执行：
echo '/usr/local/lib64
/usr/local/lib
/usr/lib
/usr/lib64'>>/etc/ld.so.conf&&ldconfig -v
开始安装：
make -j 4 && make install完成安装后配置php.ini文件：
cp php.ini-development /usr/local/php/etc/php.ini
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf修改 php.ini 相关参数：
vim /usr/local/php/etc/php.iniexpose_php = Off
short_open_tag = ON
max_execution_time = 200
max_input_time = 200
memory_limit = 100M

listen.allowed_clients = 127.0.0.1
pm = dynamic
listen.backlog = -1

pm.min_spare_servers = 50
pm.max_spare_servers = 180
request_terminate_timeout = 120
request_slowlog_timeout = 50
slowlog = var/log/slow.log创建php-cgi.sock存放目录:
mkdir /var/run/www/
chown -R www:www /var/run/www配置php-fpm.conf
vim /usr/local/php/etc/php-fpm.conf取下以下注释并填写完整路径：
pid = /usr/local/php/var/run/php-fpm.pid至此php7已经安装完成
centos6配置php-fpm开机自启动：
cp /usr/local/src/php-7.3.12/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm && chmod 755 /etc/init.d/php-fpm
#设置php开机启动:
chkconfig --add php-fpm
chkconfig php-fpm on
#启动php：
service php-fpm startcentos7以上版本配置php-fpm开机自启动：
vim /usr/lib/systemd/system/php-fpm.service添加如下变量内容：
[Unit]
Description=The PHP FastCGI Process Manager
After=syslog.target network.target
[Service]
Type=simple
PIDFile=/usr/local/php/var/run/php-fpm.pid
ExecStart=/usr/local/php/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php/etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID
[Install]
WantedBy=multi-user.target启动php-fpm服务并加入开机自启动：
systemctl enable php-fpm.service
systemctl restart php-fpm.service添加php的命令未全局变量：
修改/etc/profile文件使其永久性生效，并对所有系统用户生效，在文件末尾加上如下两行代码
PATH=$PATH:/usr/local/webserver/php/bin export PATH
执行命令source /etc/profile，执行完可通过echo $PATH 和 php -v 命令查看是否添加成功。
