5. 启动服务

[root@istester www]# service php-fpm start
Starting php-fpm: [ OK ]</pre>

6. 查看服务启动状态

[root@istester www]# service php-fpm status
php-fpm (pid 5139) is running...</pre>

7. 确认是否安装成功

1）在根目录/var/www/html 下新建文件 istester.php

[root@istester html]# echo "<?php phpinfo(); ?>" > istester.php</pre>

2）重启apache服务（查看 -》apache安装部署文档）

service httpd restart

3）浏览器访问

http://ip/istester.php

如果能看到如下界面，恭喜你，安装成功。 image

补充，

yum 自带的包版本，比较低。很多时候，系统默认安装已经安装了php版本5.3，如何升级版本呢 ？
