[root@wch02 local]# useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql 

5. 改变目录属有者

[root@wch02 local]# cd /usr/local/mysql
[root@wch02 mysql]# pwd
/usr/local/mysql
[root@wch02 mysql]# chown -R mysql .
[root@wch02 mysql]# chgrp -R mysql .
[root@wch02 mysql]# ll

[root@wch02 mysql]#

6. 配置参数，注意临时密码

[root@wch02 mysql]# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql

7. 修改系统配置文件

[root@wch02 support-files]# cp my-default.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y
[root@wch02 support-files]# cp mysql.server /etc/init.d/mysql
[root@wch02 support-files]# vim /etc/init.d/mysql #修改以下内容，必须该，否则有可能造成数据库服务启动报错
basedir=/usr/local/mysql
datadir=/data/mysql

8. 登陆，测试

[root@wch02 support-files]# cd /usr/local/mysql
[root@wch02 mysql]# mkdir data
[root@wch02 mysql]# cd bin
[root@wch02 bin]# ./mysqld_safe --user=mysql &
[root@wch02 bin]# service mysql restart
[root@wch02 bin]# ./mysql -u root -p 
Enter password:     '此时登陆所用的密码是由第6步产生的临时密码'

9. 将mysql命令加入到环境变量中

PATH=$PATH:/usr/local/mysql/bin
export PATH
将以上两行字符串添加到/etc/profile末尾。
[root@wch02 bin]# vim /etc/profile

[root@wch02 bin]# source /etc/profile
[root@wch02 bin]# mysql -u root -p
Enter password:
