编译错误

如果编译发生错误，一般都是缺少相应的依赖或依赖的版本比较低，根据错误提示安装或升级相应的依赖

编辑配置文件

# 将安装包中的配置文件复制到 /usr/local/etc 目录中
cp ./php.ini-development ./php.ini-production /usr/local/php/etc
# 复制一份配置文件并命名为 php.ini
cp /usr/local/php/etc/php.ini-development /usr/local/php/etc/php.ini
# 复制 php-fpm 配置文件并重命名
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
# 复制 www.conf 配置文件并重命名
cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf

配置环境变量

vim /etc/profile
# 添加以下
export PATH=$PATH:/usr/local/php/bin

创建 php-fpm 启动脚本

如果找不到安装包中的 init.d.php-fpm 可以参考文章最后附上的代码，进行修改

 cd ~/php-7.2.24/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

配置开机自启

# centos 方式
chkconfig add php-fpm

# 通过方式
vim /etc/rc.local
# 最后一行添加启动命令
/etc/init.d/php-fpm start

php-fpm 启动脚本代码

#! /bin/sh
