3、启动mysql
- # 查看mysql服务的状态
- [root@localhost mysqlrpm]# service mysqld status
- mysqld is stopped
- # mysql尚未启动,使用service mysqld start启动(这里是第一次启动,会初始化一些参数)
- [root@localhost mysqlrpm]# service mysqld start
- Initializing MySQL database: [ OK ]
- Installing validate password plugin: [ OK ]
- Starting mysqld: [ OK ]
- # 停止mysql服务

- Starting mysqld: [ OK ]
- # 重启mysql服务
- [root@localhost mysqlrpm]# service mysqld restart
- Stopping mysqld: [ OK ]
- Starting mysqld: [ OK ]
四、修改root密码
- # 关闭mysql服务
- [root@localhost ~]# service mysqld stop
- Stopping mysqld: [ OK ]
- # 安全模式下启动mysql,并且跳过权限表的验证
- [root@ ~]# mysqld_safe --skip-grant-tables &
- []
- [root@ ~]# --06T23::.604144Z mysqld_safe Logging to '/var/log/mysqld.log'.
- --06T23::.674987Z mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
- # 准备登陆
- mysql -u root -p
- # 这里随便输入密码,都可以进入mysql
- Enter password:

五、远程访问mysql
1、centos开启防火墙端口3306
- # 开放3306端口
- [root@ ~]# /sbin/iptables -I INPUT -p tcp --dport -j ACCEPT
- # 保存
- [root@ ~]# /etc/rc.d/init.d/iptables save
- iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ]
- # 查看防火墙的状态
- [root@ ~]# /etc/init.d/iptables status
- Table: filter
- Chain INPUT (policy ACCEPT)
- num target prot opt source destination
- ACCEPT tcp -- 0.0.0.0/ 0.0.0.0/ tcp dpt:
- ACCEPT tcp -- 0.0.0.0/ 0.0.0.0/ tcp dpt:
- ACCEPT tcp -- 0.0.0.0/ 0.0.0.0/ tcp dpt:
- ACCEPT all -- 0.0.0.0/ 0.0.0.0/ state RELATED,ESTABLISHED
- ACCEPT icmp -- 0.0.0.0/ 0.0.0.0/
- ACCEPT all -- 0.0.0.0/ 0.0.0.0/
- ACCEPT tcp -- 0.0.0.0/ 0.0.0.0/ state NEW tcp dpt:
- REJECT all -- 0.0.0.0/ 0.0.0.0/ reject-with icmp-host-prohibited
- Chain FORWARD (policy ACCEPT)
- num target prot opt source destination
- REJECT all -- 0.0.0.0/ 0.0.0.0/ reject-with icmp-host-prohibited
- Chain OUTPUT (policy ACCEPT)
- num target prot opt source destination
- # 删除刚刚添加的端口
- # 这里我原先已经开放了3306端口,再次添加又增加了一个3306,所以显示2个3306,这里我将num为2的那个3306删除
- [root@ ~]# iptables -D INPUT
- # 查看防火墙的状态(奇怪的是我原本也开放的有80端口,莫名其妙没了...)
- [root@ ~]# iptables -L -n --line-number
- Chain INPUT (policy ACCEPT)
- num target prot opt source destination
- ACCEPT tcp -- 0.0.0.0/ 0.0.0.0/ tcp dpt:
- ACCEPT tcp -- 0.0.0.0/ 0.0.0.0/ tcp dpt:
- ACCEPT all -- 0.0.0.0/ 0.0.0.0/ state RELATED,ESTABLISHED
- ACCEPT icmp -- 0.0.0.0/ 0.0.0.0/
- ACCEPT all -- 0.0.0.0/ 0.0.0.0/
- ACCEPT tcp -- 0.0.0.0/ 0.0.0.0/ state NEW tcp dpt:
- REJECT all -- 0.0.0.0/ 0.0.0.0/ reject-with icmp-host-prohibited
- Chain FORWARD (policy ACCEPT)
- num target prot opt source destination
- REJECT all -- 0.0.0.0/ 0.0.0.0/ reject-with icmp-host-prohibited
- Chain OUTPUT (policy ACCEPT)
- num target prot opt source destination
2、修改mysql表,允许远程访问
- # 登陆
- [root@ ~]# mysql -uroot -p
- Enter password:
- Welcome to the MySQL monitor. Commands end with ; or \g.
- Your MySQL connection id is
- Server version: 5.7.
- Copyright (c) , , Oracle and/or its affiliates. All rights reserved.
- Oracle is a registered trademark of Oracle Corporation and/or its
- affiliates. Other names may be trademarks of their respective
- owners.
- Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
- mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '' WITH GRANT OPTION;
- ERROR (HY000): You must reset your password using ALTER USER statement before executing this statement.
- # 在设置远程登录原先是提示错误。百度一番,需要设置root密码,好吧,我原先是1234,现在还设置为1234
- mysql> SET PASSWORD = PASSWORD('');
- ERROR (HY000): Your password does not satisfy the current policy requirements
- # 发现是密码太脆弱,究其根本是由于mysql有密码验证的策略,那么这里设置一下
- # 设置密码强度检查等级为0,/LOW、/MEDIUM、/STRONG。
- mysql> set global validate_password_policy=;
- Query OK, rows affected (0.00 sec)
- # 设置密码长度:-->
- mysql> select @@validate_password_length;
- +----------------------------+
- | @@validate_password_length |
- +----------------------------+
- | |
- +----------------------------+
- row in set (0.00 sec)
- mysql> set global validate_password_length=;
- Query OK, rows affected (0.00 sec)
- mysql> select @@validate_password_length;
- +----------------------------+
- | @@validate_password_length |
- +----------------------------+
- | |
- +----------------------------+
- row in set (0.00 sec)
- # 设置密码为1234
- mysql> SET PASSWORD = PASSWORD('');
- Query OK, rows affected, warning (0.00 sec)
- # 设置允许远程访问
- mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '' WITH GRANT OPTION;
- Query OK, rows affected, warning (0.00 sec)
- # 刷新权限
- mysql> flush privileges;
- Query OK, rows affected (0.00 sec)
- # 退出
- mysql> exit;
- Bye
3、windows下远程连接vm12下centos6.9的mysql
- Microsoft Windows [版本 6.1.]
- 版权所有 (c) Microsoft Corporation。保留所有权利。
- C:\Users\Administrator>mysql -h 192.168.22.130 -u root -p
- Enter password: ****
- Welcome to the MySQL monitor. Commands end with ; or \g.
- Your MySQL connection id is
- Server version: 5.7. MySQL Community Server (GPL)
