4、创建配置文件

mkdir /home/{mysql_data, mysql_log}
vim /home/mysql_data/my.cnf
[mysqld]
port=3306
datadir=/home/mysql_data
log_error=/home/mysql_log/error.log
basedir=/home/mysql

5、创建MySQL库

添加用户：
groupadd mysql
useradd -g mysql mysql -s /sbin/nologin

6、启动数据库

初始化：
./bin/mysqld --defaults-file=/etc/my.cnf --basedir=/home/mysql --datadir=/home/mysql_data --user=mysql --initialize

启动：
 /home/mysql/bin/mysqld --defaults-file=/home/mysql_data/my.cnf --user=mysql

查看进程：
[root@master2 home]# ps aux | grep mysql
mysql     9356  2.0  1.1 1188484 180208 pts/0  Sl+  14:45   0:00 /home/mysql/bin/mysqld --defaults-file=/etc/my.cnf --user=mysql

 7、登录数据库

查看初始密码：
[root@master2 home]# grep "root@localhost" /home/mysql_log/error.log 
2018-09-04T06:41:21.468338Z 1 [Note] A temporary password is generated for root@localhost: 5#3vslHQt;m-

登录数据库并修改密码：
[root@master2 home]# mysql -uroot -p5#3vslHQt;m-
mysql: [Warning] Using a password on the command line interface can be insecure.
