1、
运维人员需要考虑安全性、稳定性。
安装：
解压进入到目录：
shell > tar zxf php-7.2.12.tar.gz
shell > cd php-7.2.12安装依赖软件：
yum -y install libxml2-devel libjpeg-devel libpng-devel freetype-devel curl-devel openssl-devel编译参数配置：
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-fpm --with-fpm-user=www --with-fpm-group=www --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --enable-ftp --with-gd --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --with-libzip --enable-soap --without-pear --with-gettext --disable-fileinfo --enable-maintainer-zts编译并安装到目录：
make && make install
查看PHP的安装目录：
cd /usr/local/php
跟mysql相关的模块：
[root@server01 bin]# ./php -m |grep mysql
mysqli
mysqlnd
pdo_mysql
man文档：
man ./php.1
配置：
使用php-fpm进行管理php服务，有两个配置文件：
①php.ini #默认php配置文件
②php-fpm.conf #php-fpm相关的配置 复制配置文件：
shell > cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
shell > cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
shell > cp /root/soft/php-7.2.12/php.ini-development /usr/local/php/etc/php.ini启动php-fpm服务：
添加启动服务：
shell > cp /root/soft/php-7.2.12/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
shell > chmod +x /etc/init.d/php-fpm
shell > chkconfig --add php-fpm

[root@server01 fpm]# service php-fpm start

[root@server01 fpm]#
[root@server01 fpm]# service php-fpm status

说明：Default-start和Default-stop：这个跟chkconfig 类似。
脚本还是要多练习的。
添加环境变量：
[root@server01 fpm]# echo "PATH=/usr/local/php/bin:$PATH" >> /etc/profile
[root@server01 fpm]# source /etc/profile
php安装脚本及其初始化配置 ：
#!/bin/bash
php_install(){
#php编译安装
#和nginx使用相同的用户,如果没有就创建
`id www` &> /dev/null
[ $? -ne 0 ] && useradd -s /sbin/nologin -M www
#解决依赖
yum -y install libxml2-devel libjpeg-devel libpng-devel freetype-devel curl-devel openssl-devel
#解压
tar xvf php-7.2.12.tar.gz
cd php-7.2.12
