Ubuntu离线安装 MySQL 5.7

一、所需环境

操作系统:Ubuntu 20.04

数据库:MySQL 5.7.34

网络情况:内网服务器,无法访问互联网资源

二、提前下载所需以来及安装包

1、所需依赖包

bash 复制代码
(1)libmecab2 
http://archive.ubuntu.com/ubuntu/pool/universe/m/mecab/libmecab2_0.996-1.2ubuntu1_amd64.deb
(2)libaio1 
http://archive.ubuntu.com/ubuntu/pool/main/liba/libaio/libaio1_0.3.110-2_amd64.deb
(3)libtinfo5 
http://archive.ubuntu.com/ubuntu/pool/universe/n/ncurses/libtinfo5_6.2-0ubuntu2_amd64.deb

2、下载MySQL安装包

演示所用版本:

bash 复制代码
https://cdn.mysql.com/archives/mysql-5.7/mysql-server_5.7.34-1ubuntu18.04_amd64.deb-bundle.tar

大家可以去官网下载自己需要的版本:
https://downloads.mysql.com/archives/community/

三、安装依赖,以及安装MySQL

1、将下载的依赖以及安装包上传到自己指定的文件夹(演示用/opt)

2、安装依赖包

bash 复制代码
sudo dpkg -i libmecab2_0.996-1.2ubuntu1_amd64.deb
sudo dpkg -i libaio1_0.3.110-2_amd64.deb
sudo dpkg -i libtinfo5_6.2-0ubuntu2_amd64.deb

3、安装MySQL

(1)解压安装包

bash 复制代码
sudo tar -xvf mysql-server_5.7.34-1ubuntu18.04_amd64.deb-bundle.tar

解压后目录如下:

(2)安装MySQL

bash 复制代码
sudo dpkg -i mysql-common_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg-preconfigure mysql-community-server_5.7.34-1ubuntu18.04_amd64.deb    //此步需要输入数据的root密码
sudo dpkg -i libmysqlclient20_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i libmysqlclient-dev_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i libmysqld-dev_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i mysql-community-client_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i mysql-client_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i mysql-common_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i mysql-community-server_5.7.34-1ubuntu18.04_amd64.deb
sudo dpkg -i mysql-server_5.7.34-1ubuntu18.04_amd64.deb

(3)验证MySQL的安装是否成功:

mysql -u root -p //输入密码

查看mysql状态:

bash 复制代码
sudo systemctl status mysql.service

四、MySQL配置

1、开启MySQL远程访问

(1)修改mysqld.cnf配置文件

bash 复制代码
sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf

打开文件后将下面一行注释

#bind-address = 127.0.0.1(修改后)

(2)执行以下命令开启远程访问限制(注意:下面命令开启的IP是 192.168.0.1,如要开启所有的,用%代替IP):

bash 复制代码
grant all privileges on *.* to 'root'@'192.168.0.1' identified by 'password' with grant option;

然后再输入下面两行命令

bash 复制代码
flush privileges; 

exit;

2、防火墙开打开端口

bash 复制代码
1、查看防火墙状态,inactive是关闭,active是开启。
sudo ufw status
 
2、开启防火墙。
sudo ufw enable
 
3、关闭防火墙。
sudo ufw disable
 
4、开启3306端口访问
sudo ufw allow 3306/tcp

注意:UFW防火墙开发 3306端口,UFW处于 Status: inactive 时(sudo ufw status verbose),可以不执行上面操作命令

五、配置文件参考

修改mysql配置文件

/etc/mysql/mysql.conf.d/mysqld.cnf

bash 复制代码
datadir         = /var/lib/mysql
log-error       = /var/log/mysql/error.log
