Debian9解压安装MySQL（版本5.7.31）

一、下载

MySQL下载官网：https://dev.mysql.com/downloads/mysql

根据目标主机的型号官网下载对应的mysql安装包，安装类型和名字如下：

mysql-server_5.7.31-1debian9_amd64.deb-bundle.tar

二、解压

tar -xvf mysql-server_5.7.31-1debian9_amd64.deb-bundle.tar

三、安装

根据需要安装必要的deb包，可以用dpkg --info 指定的包.deb查看依赖

1、先安装依赖

apt install libaio1 libnuma1 libmecab2 -y

2、然后依次按以下的顺序安装

（1）dpkg -i mysql-common_5.7.31-1debian9_amd64.deb
（2）dpkg -i mysql-community-client_5.7.31-1debian9_amd64.deb
（3）dpkg -i mysql-client_5.7.31-1debian9_amd64.deb
（4）dpkg -i mysql-community-server_5.7.31-1debian9_amd64.deb（注意：这一步，需要设置MySQL的root密码，步骤是第3步）
（5）dpkg -i mysql-server_5.7.31-1debian9_amd64.deb

3、设置密码

4、确认密码

四、配置

如果需要远程访问MySQL，修改配置，默认只能本地访问

cd /etc/mysql/mysql.conf.d/

vim mysqld.cnf

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
log-error       = /var/log/mysql/error.log
# By default we only accept connections from localhost
bind-address    = 127.0.0.1 # 修改为0.0.0.0即可
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

# 字符编码设置为utf8
character_set_server = utf8
init_connect = 'SET NAMES utf8'

1、重启

systemctl restart mysql

2、查看状态

systemctl status mysql

3、修改root权限，默认是localhost

mysql -u root -p

mysql> use mysql
mysql> update user set Host="%" where User="root";
mysql> flush privileges;
mysql> select Host,User from user;

4、查看设置的字符集

mysql> show variables like "%character%";show variables like "%collation%";
