4、创建配置文件

mkdir /home/{mysql_data, mysql_log}
vim /home/mysql_data/my.cnf
[mysqld]
port=
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       2.0  1.1   pts/  Sl+  :   : /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
--04T06::.468338Z  [Note] A temporary password is generated for root@localhost: #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.
ERROR  (): Access denied for user 'root'@'localhost' (using password: YES)
-bash: m-: command not found
[root@master2 home]# mysql -uroot -p"5#3vslHQt;m-"
