这篇文章主要为大家详细介绍了Ubuntu 18.04 安装mysql 5.7的相关资料，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

Ubuntu18.04安装mysql5.7，供大家参考，具体内容如下

1.1安装

首先执行下面三条命令：

				?

									# 安装mysql服务

									sudo apt-get install mysql-server

									# 安装客户端

									sudo apt install mysql-client

									# 安装依赖

									sudo apt install libmysqlclient-dev

									# 检查状态

									sudo netstat -tap | grep mysql

1.2设置root密码

mysql5.7安装完成后普通用户不能进mysql，原因：root的plugin被修改成了auth_socket，用密码登陆的plugin应该是mysql_native_password，直接用root权限登录就不用密码,修改root密码和登录验证方式：

				?

									$ sudo su

									# mysql

									mysql>

									mysql> select user, plugin from mysql.user;

									+------------------+-----------------------+

									| user | plugin |

									+------------------+-----------------------+

									| root | auth_socket |

									| mysql.session | mysql_native_password |

									| mysql.sys | mysql_native_password |

									| debian-sys-maint | mysql_native_password |

									+------------------+-----------------------+

									4 rows in set (0.00 sec)

									mysql> update mysql.user set authentication_string=PASSWORD('123456'), plugin='mysql_native_password' where user='root';

									mysql> flush privileges;

									mysql> exit

									Bye

									# exit

									$ sudo /etc/init.d/mysql restart

									$ mysql -uroot -p

									Enter password: 

									Welcome to the MySQL monitor. Commands end with ; or \g.

									Your MySQL connection id is 2

									mysql>

1.3配置mysql远程登录

				?

									# 修改配置文件，注释掉bind-address = 127.0.0.1

									$ sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf

									# 保存退出，然后进入mysql服务，执行授权命令：

									$ mysql -uroot -p

									mysql> grant all on *.* to root@'%' identified by '123456' with grant option;

									Query OK, 0 rows affected, 1 warning (0.00 sec)

									mysql> flush privileges;

									Query OK, 0 rows affected (0.00 sec)

									mysql> exit

									Bye

									$ sudo /etc/init.d/mysql restart
