1.查看Linux系统信息

[root@abc ~]# uname -a

2.查看Apache版本信息

如果是通过yum，或者是rpm安装的，可以使用rpm -qa |gerp httpd 来查看；

[root@abc ~]# rpm -qa |grep httpd
httpd-tools-2.2.15-56.el6.centos.3.x86_64
httpd-2.2.15-56.el6.centos.3.x86_64
[root@abc ~]# httpd -v
Server version: Apache/2.2.15 (Unix)

3.查看php的版本信息

如果是通过yum，或者是rpm包安装的，可以使用rpm -qa |grep php来查看；

也可以通过php -v来查看php版本信息

[root@abc ~]# php -v
PHP 5.6.30 (cli) (built: Jan 19 2017 08:09:42)

一般情况下，大多是通过安装lamp后，使用phpinfo的测试页来查看安装的php的信息；

4. 查看mysql的版本信息

如果是通过yum安装的，或者是rpm包安装的，可以使用rpm -qa |grep mysql 来查看

[root@abc ~]# rpm -qa |grep mysql
php-mysqlnd-5.6.30-1.el6.remi.x86_64
mysql-community-common-5.7.17-1.el6.x86_64

mysql57-community-release-el6-9.noarch
mysql-community-server-5.7.17-1.el6.x86_64
[root@iZbp13nush4c657vxdn89lZ mysql]#

也可以使用mysql -v 或者是--help|grep Distrib来查看

[root@abc ~]# mysql -V
mysql  Ver 14.14 Distrib 5.7.17, for Linux (x86_64) using  EditLine wrapper
[root@abc ~]# mysql --help |grep Distrib
