# 初始化数据库，
cd /apps/mysql
./bin/mysqld --initialize --user=mysql --basedir=/apps/mysql/ --datadir=/data/mysql7006/data/

# 依据情况修改support-files/mysql.server
cp support-files/mysql.server /etc/init.d/mysql
systemctl start mysql.service

# 添加开机启动
chkconfig mysql.server on

# 修改后清空linux的history记录
history -c

# 登陆测试：
/apps/mysql/bin/mysql -u root --port=7006 --socket=/data/mysql7006/mysql.sock -p

# 防火墙
firewall-cmd --zone=public --add-port=7006/tcp --permanent
systemctl restart firewalld

# 赋权给登陆用户
use mysql;
grant all privileges on *.* to user@'ip' identified by "password";
flush privileges;
select host,user,password from user;

## 使用mysql_config_editor 制作登录文件
/apps/mysql/bin/mysql_config_editor set --login-path=root_pass --user=root --port=7006 --socket=/data/mysql7006/mysql.sock --password
## 输入密码：******
## 文件会加密存储于用户根目录下.mylogin.cnf
/apps/mysql/bin/mysql_config_editor print --all
## 下次登录时直接敲：
/apps/mysql/bin/mysql --login-path=root_pass

# 再省事一些：set alias
# 打开file .bashrc，添加
alias db7006='/apps/mysql/bin/mysql --login-path=root_pass'
# 然后退出执行：
source .bashrc
## 下次登录时直接敲：
db7006
