1.准备好安装包 上传更目录

本文基于mysql 5.7.22

2.

编辑my.cnf配置文件，放在当前mysql安装目录下，配置文件路径/home/2iuser/mysql/my.cnf 。

[client]   
port=3306  
socket=/home/[client]   
port=3306  
socket=/home/whr/mysql/mysql.sock  

[mysqld]
port=3306
basedir=/home/whr/mysql
datadir=/home/whr/mysql/data
pid-file=/home/whr/mysql/mysql.pid
socket=/home/whr/mysql/mysql.sock
log_error=/home/whr/mysql/error.log
server-id=100/mysql/mysql.sock  

3.进入mysql目录，开始安装mysql。

bin/mysqld --defaults-file=/home/whr/mysql/my.cnf --initialize --user=root --basedir=/home/whr/mysql --datadir=/home/whr/mysql/data 

4.启动

bin/mysqld_safe  --defaults-file=/home/whr/mysql/my.cnf  --user=root &

5.获取密码

cat error.log | grep root@localhost

6.登陆

bin/mysql -u root -p -S /home/whr/mysql/mysql.sock

7.修改密码

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123456');
flush privileges;

8.设置远程访问

grant all PRIVILEGES on *.* to root@'%'  identified by 'root的密码';
flush privileges;

ps:

1.启动如果报错

121206 11:14:09 [ERROR] Can't start server: Bind on TCP/IP port: Address already in use
121206 11:14:09 [ERROR] Do you already have another mysqld server running on port: 3306 ?

解决：

ps aux |grep mysq*

查看进程，然后全部kill掉，重试。

2.多注意情动方式，必须制定sock目录
