1.安装之前,先创建mysql用户
[root@linuxprobe_nfs ~]# useradd mysql -s /sbin/nologin -M [root@linuxprobe_nfs ~]# id mysql uid=500(mysql) gid=500(mysql) groups=500(mysql)
2.软件包的下载及解压
[root@linuxprobe_nfs ~]# mkdir /home/chenfan/tools -p [root@linuxprobe_nfs ~]# cd /home/chenfan/tools 在http://dev.mysql.com/downloads/mysql/官网上下载mysql-5.5.32-linux2.6-x86_64.tar.gz [root@linuxprobe_nfs tools]# ls mysql-5.5.32-linux2.6-x86_64.tar.gz [root@linuxprobe_nfs tools]# tar zxvf mysql-5.5.32-linux2.6-x86_64.tar.gz [root@linuxprobe_nfs tools]# ls mysql-5.5.32-linux2.6-x86_64 mysql-5.5.32-linux2.6-x86_64.tar.gz [root@linuxprobe_nfs local]# mv mysql-5.5.32-linux2.6-x86_64 /usr/local/mysql-5.5.32 ###免编译安装 [root@linuxprobe_nfs local]# cd /usr/local [root@linuxprobe_nfs local]# ln -s mysql-5.5.32 mysql ###此处的软链接为了版本升级提供了便利
3.初始化数据库
[root@linuxprobe_nfs local]# mysql/scripts/mysql_install_db --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ --user=mysql ###此处如果初始化发生错误,删除data目录下的内容,rm -fr mysql/data/*,重新初始化。
4.生成MySQL配置文件
[root@linuxprobe_nfs local]# cd mysql [root@linuxprobe_nfs mysql]# cp support-files/my-small.cnf /etc/my.cnf
5.授权管理文件
[root@linuxprobe_nfs ~]# chown -R mysql:mysql /usr/local/mysql/ [root@linuxprobe_nfs ~]# ls -ld /usr/local/mysql/ drwxr-xr-x. 13 mysql mysql 4096 Jun 24 17:21 /usr/local/mysql/
6.设置科学的启动方式
[root@linuxprobe_nfs mysql]# cp support-files/mysql.server /etc/init.d/mysqld [root@linuxprobe_nfs mysql]# chmod +x /etc/init.d/mysqld [root@linuxprobe_nfs mysql]# /etc/init.d/mysqld start Starting MySQL... SUCCESS! [root@linuxprobe_nfs mysql]# chkconfig --add mysqld [root@linuxprobe_nfs mysql]# chkconfig mysqld on [root@linuxprobe_nfs mysql]# chkconfig --list mysqld mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off ### 设置开机自启动mysql
7.配置MySQL环境变量
[root@linuxprobe_nfs mysql]# echo 'PATH=/usr/local/mysql/bin:$PATH' >> /etc/profile [root@linuxprobe_nfs mysql]# source /etc/profile [root@linuxprobe_nfs mysql]# echo $PATH /usr/local/mysql/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin ###此处PATH路径的设置为了后续mysql命令的使用
8.mysql登陆与密码设置
[root@linuxprobe_nfs mysql]# mysql Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 5.5.32 MySQL Community Server (GPL) Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql> [root@linuxprobe_nfs mysql]# mysqladmin -uroot password 'chenfan' ###密码的设置 [root@linuxprobe_nfs mysql]# mysql -uroot -p Enter password: chenfan ###交互式登陆 ###至此完成MySQL的全部初始安装与配置(责任编辑:好模板) |
