检查系统是否已经有mysql用户，如果没有则创建

[root@server mysql-5.7.17]
# cat /etc/passwd | grep mysql
[root@server mysql-5.7.17]
# cat /etc/group | grep mysql

创建mysql用户（但是不能使用mysql账号登陆系统）

[root@server mysql-5.7.17]
# groupadd mysql
[root@server mysql-5.7.17]
# useradd -g mysql -s /sbin/nologin mysql

修改权限

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

# vim /etc/init.d/mysqld
#####添加安装目录及数据目录
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data

[root@server mysql-5.7.17]
# chkconfig --add mysqld
[root@server mysql-5.7.17]
# chkconfig --level 35 mysqld on
|
进入/etc/profile设置环境变量
|

|
[root@server mysql-5.7.17]
# vim /etc/profile
export PATH=/usr/local/mysql/bin:$PATH
#在末尾添加
[root@server mysql-5.7.17]
# source /etc/profile
|
进入安装路径，执行初始化配置脚本，创建系统自带的数据库和表
#mysql5.7之前版本初始化配置表命令：
|
1
|
#script/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql/
|
#mysql5.7已经放弃使用了，而且也没有script目录，可以使用下面这个
|
1
|
#[root@server mysql-5.7.17]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql/
|
生成的初始密码位于：
方法一：
|
1
2
|
[root@server mysql-5.7.17]
# grep 'temporary password' /var/log/mysqld.log
2016-07-08T02:25:46.311098Z 1 [Note] A temporary password is generated
for
root@localhost: MtPqF0/oN5zo
|
即初始密码为 MtPqF0/oN5zo （密码是随机产生的，每台机器产生的都不一样哦）
方法二：
|
1
2
|
[root@server mysql-5.7.17]
# cat /root/.mysql_secret
# The random password set for the root userat Fri Jan 10 20:00:34 2014 (local time): aJqZsA2m
|
这里的aJqZsA2m就是生成的root随机密码啦
接下来，启动数据库,重设root密码
|
1
|
[root@server mysql-5.7.17]
# /etc/init.d/mysqld start
|
|
1
2
3
|
[root@server mysql-5.7.17]
# mysql -uroot -p
Enter password:
# 输入刚刚的随机密码链接数据库
mysql> ALTER USER
'root'
@
'localhost'
IDENTIFIED BY
'新密码'
;
