5. Configure mysql configuration file under etc

vim /etc/my.cnf    ---将文件中所有内容注释掉在添加如下内容

[root@youxi1 mysql]# vim /etc/my.cnf
[mysqld]
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port=3306
socket=/usr/local/mysql/mysql.sock
character-set-server=utf8
log-error=/var/log/mysqld.log
pid-file=/tmp/mysqld.pid
[mysql]
socket=/usr/local/mysql/mysql.sock
[client]
socket=/usr/local/mysql/mysql.sock

6. Configure environment variables for easy management

vim /etc/profile.d/mysql.sh
最后一行加上这个
export PATH=/usr/local/mysql/bin:$PATH
保存刷新
source /etc/profile.d/mysql.sh

7. Add startup script and change password

cp support-files/mysql.server /etc/init.d/mysqld

chmod +x /etc/init.d/mysqld

vim /etc/init.d/mysqld
basedir=/usr/local/mysql　　  #第46行  补全安装目录
datadir=/usr/local/mysql/data  #第47行  补全数据所在目录

/etc/init.d/mysqld start      #刷新

mysqladmin -u root -p'初始密码'  password '新密码'  #新密码必须包含大小写英文、数字、特殊符号。

#登陆mysql
mysq -uroot -p'新密码'
