2.2 检查mysql服务状态
1 systemctl status mysql.service
显示如下结果说明mysql服务是正常的:
3.配置远程访问
在Ubuntu下MySQL缺省是只允许本地访问的,使用workbench连接工具是连不上的;
如果你要其他机器也能够访问的话,需要进行配置;
3.1 首先用根用户进入
1 sudo mysql -uroot -p
登入root进行其他设置:
1 GRANT ALL PRIVILEGES ON *.* TO root@localhost IDENTIFIED BY " 123456 " ;
其中 root@localhos , localhost 就是本地访问,配置成 % 就是所有主机都可连接;
第二个 ‘123456‘ 为你给新增权限用户设置的密码, % 代表所有主机,也可以是具体的ip;
不过这随设置了 % 但我root通过工具还是登陆不进去,可能是为了安全性,所以新建数据库和用户;
3.2 新建数据库和用户
用root用户新建数据和用作远程访问的用户
1 ## 1 创建数据库weixx
2 CREATE DATABASE weixx;
3 ## 2 创建用户wxx(密码654321) 并允许wxx用户可以从任意机器上登入mysql的weixx数据库
4 GRANT ALL PRIVILEGES ON weixx.* TO wxx @" % " IDENTIFIED BY " 654321 " ;
4.使用workbench连接数据库
打开workbench进行连接配置:
配置完成后,在主界面选择weixx数据库进行连接:
