一、配置eaccelerator扩展模块生效
注意事项：如果使用Zend扩展缓存模块，[eaccelerator]段配置要放在Zend的 内容配置前，否则会报错

#==》创建eaccelerator缓存目录，此目录可以用tmpfs内存文件系统存储或SSD固态硬盘
[root@lnmp ~]# mkdir -p /tmp/eaccelerator   
[root@lnmp ~]# ls -ld /tmp/eaccelerator/
drwxr-xr-x 2 nginx nginx 4096 Jul 10 17:02 /tmp/eaccelerator/
[root@lnmp ~]# grep "nginx" /application/nginx/conf/nginx.conf
user  nginx;
[root@lnmp ~]# chown -R nginx.nginx /tmp/eaccelerator/         #==》必须赋予nginx虚拟用户权限，否则会出现权限问题
[root@lnmp ~]# ls -ld /tmp/eaccelerator/
drwxr-xr-x 2 nginx nginx 4096 Jul 10 17:02 /tmp/eaccelerator/
[root@lnmp ~]#cat >> /application/php/lib/php.ini << EOF

#==》仅检查eaccelerator插件情况配置，可以不重启PHP服务，但如果使其生效，还需重启PHP服务
