默认情况下SUSE Linux中httpd和mysql是没有启动的，
如 直接用mysql命令的话 =〉
Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'
启动服务的方法如下：
1，桌面操作方式直接用YasT 在 系统-〉服务 里面启动即可
2，命令形式直接启动mysql服务，
命令 方式一：#service [serviceName] [option]
service 可以是apache2，mysql; optition 可以是 start，restart, stop
如：
linux-heng:/srv/www/htdocs # service mysql start
Starting service MySQL done
linux-heng:/srv/www/htdocs # service apache2 restart
Syntax OK
Shutting down httpd2 (waiting for all children to terminate) done
Starting httpd2 (prefork) done
linux-heng:/srv/www/htdocs # service apache2 stop
Shutting down httpd2 (waiting for all children to terminate) done
linux-heng:/srv/www/htdocs # service mysql stop
Shutting down service MySQL done
命令方式二：#rc[service] [optition]
也就是服务名前加 "rc "，如 rcapache2, rcmysql，optiton同命令方式一
如：
linux-heng:/srv/www/htdocs # rcmysql start
Starting service MySQL done
linux-heng:/srv/www/htdocs # rcapache2 start
Apache is already running (/var/run/httpd2.pid) done
linux-heng:/srv/www/htdocs # service apache2 restart
Syntax OK
Shutting down httpd2 (waiting for all children to terminate) done
Starting httpd2 (prefork) done
linux-heng:/srv/www/htdocs # service mysql stop
Shutting down service MySQL done
