配置

以下操作都是 root 身份

useradd -g mysql -s /sbin/nologin mysql

mkdir -p /data/services/mysql-5.7.25/etc
mkdir -p /data/services/mysql-5.7.25/tmp
mkdir -p /data/services/mysql-5.7.25/data

touch /data/services/mysql-5.7.25/etc/my.cnf
touch /data/services/mysql-5.7.25/etc/mysql.log

chown -R mysql:mysql /data/services/mysql-5.7.25/

修改 my.cnf

[mysqld]
basedir = /data/services/mysql-5.7.25
datadir = /data/services/mysql-5.7.25/data
bind-address = 10.0.0.2
port = 3306
user = mysql
#server_id = 92
socket = /data/services/mysql-5.7.25/tmp/mysql.sock

[mysqld_safe]
log-error = /data/services/mysql-5.7.25/tmp/mysql.log
pid-file = /data/services/mysql-5.7.25/tmp/mysql.pid

初始化

./bin/mysqld --initialize --user=mysql

启动

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

修改 vi /etc/init.d/mysqld

basedir=xxx
datadir=xxx

chkconfig mysqld on
service mysqld start

连接 & 修改密码

./bin/mysql -uroot -p

alter user 'root'@'localhost' identified by 'root123';

注意

5.7 开始初始化密码，有密码强度校验，validate_password_policy 有以下取值：

默认是1，即MEDIUM，所以刚开始设置的密码必须符合长度，且必须含有数字，小写或大写字母，特殊字符。

有时候，只是为了自己测试，不想密码设置得那么复杂，譬如说，我只想设置root的密码为123456。

必须修改两个全局参数：

set global validate_password_policy=0;
set global validate_password_length=1;
