Linux下安装、启动MySQL_MySQL
bitsCN.com
三四年没有安装过mysql+apache+PHP的环境了,我以前是做银行性能测试外包服务的,在甲方开发中心遇到这样环境的项目也比较少,大多是WebLogic/WebSphere+Oracle/DB2架构的大型系统。涉足电商行业方面的项目,不得不再去温故那些几乎遗忘的IIS、apache、MSsql、mysql等环境。
平台:VMware上虚拟的centos4.7
宿主机:windows
安装mysql前准备:
1、检查该环境中是否已安装mysql,检查方法:netstat –ano命令查看mysql默认端口3306是否存在;或者再命令行中执行mysql
2、下载mysql安装包
在http://www.mysql.com/downloads/mysql/#downloads下载mysql安装包:
MySQL-server-5.5.28-1.linux2.6.i386.rpm
MySQL-client-5.5.28-1.linux2.6.i386.rpm
使用rpm –ivh命令来安装mysql,这里不说啦。
先来了解一下mysql数据库默认的一些主要目录:
1、数据库目录 /var/lib/mysql/
2、配置文件 /usr/share/mysql(mysql.server命令及配置文件)
3、相关命令 /usr/bin (mysqladmin mysqldump等命令)
4、启动脚本 /etc/rc.d/init.d/(启动脚本文件mysql的目录)
安装后通过netstat –ano命令查看mysql默认端口3306是否存在,如果不存在,按下面的方法启动mysql服务。
启动mysql服务:
[root@localhostmysql]# pwd/usr/share/mysql[root@localhostmysql]# ./mysql.server startStartingMySQL...[ 确定 ][root@localhostmysql]# netstat -anoActiveInternet connections (servers and established)ProtoRecv-Q Send-Q Local Address Foreign Address State Timertcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN off (0.00/0/0)[root@localhostmysql]# mysqlWelcometo the MySQL monitor.

启动与停止
1、启动
MySQL安装完成后启动文件mysql在/etc/init.d目录下,在需要启动时运行下面命令即可。
[root@localhost mysql]# /etc/init.d/mysql start
2、停止
[root@localhost mysql] # /usr/bin/mysqladmin -u root -p shutdown
3、自动启动
1)察看mysql是否在自动启动列表中
[root@localhost mysql] # /sbin/chkconfig –list
2)把MySQL添加到你系统的启动服务组里面去
[root@localhost mysql] # /sbin/chkconfig – add mysql
3)把MySQL从启动服务组里面删除。
[root@localhost mysql] # /sbin/chkconfig – del mysql
