cp php.ini-production /usr/local/php56/etc/php.ini
cp /usr/local/php56/etc/php-fpm.conf.default /usr/local/php56/etc/php-fpm.conf
cp sapi/fpm/init.d.php-fpm /etc/init.d/php56-fpm
[root@localhost php-5.6.40]# chmod +x /etc/init.d/php56-fpm
[root@localhost php-5.6.40]# /etc/init.d/php56-fpm start

4. 配置环境变量

[root@localhost php-5.6.40]# vim /etc/profile
PATH=$PATH:/usr/local/php56/bin
export PATH

5. 添加运行用户组

useradd www -M -d / -s /usr/sbin/nologin

6. 配置开机启动

[root@localhost wwwroot]# chkconfig --add php56-fpm
[root@localhost wwwroot]# chkconfig php56-fpm on
[root@localhost wwwroot]# systemctl enable php56-fpm
php56-fpm.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig php56-fpm on
[root@localhost wwwroot]#

7.PHP进程数的设置

[root@localhost php-5.6.40]# vim /usr/local/php56/etc/php-fpm.conf
pm.max_children = 100
pm.start_servers = 30
pm.min_spare_servers = 20
pm.max_spare_servers = 100
pm.max_requests = 500

8.PHP禁用危险函数

在 /usr/local/php56/etc/php.ini 下添加
disable_functions = phpinfo,passthru,chroot,shell_exec,proc_get_status,ini_alter,ini_restore,dl,pfsockopen,symlink,popen,stream_socket_server
