Linux学习笔记（三) 、docker学习（3）：docker安装mysql-server

最近在docker 上处理一些个人服务，便在空闲时间捣鼓了一下mysql8在docker上的安装、配置、远程连接等的问题。

# 事先开启防火墙端口，开好后重启一下docker。
firewall-cmd --zone=public --add-port=3306/tcp --permanent
firewall-cmd --reload
----------------mysql---配置
docker pull mysql/mysql-server:8.0.22
# docker run -d -p 3306:3306 --name mysql_2020 -e MYSQL_ROOT_PASSWORD=1234 mysql/mysql-server:8.0.22 
# 下面这个添加了运行内存控制，推荐大家不确定控制多少内存的情况下，先使用上面的一个被注掉的命令
docker run -e TZ="Asia/Shanghai" -d -p 3306:3306 --name mysql_2021v1 -m 600M --memory-swap 800M  -e MYSQL_ROOT_PASSWORD=1234 mysql/mysql-server:8.0.22 

docker exec -it [container_id] /bin/bash   ##进入容器
mysql -uroot -p1234
show global variables like 'port';

# 使用mysql8 数据库--远程连接
mysql > use mysql;
# 特定用户的host 修改
mysql > update user set host='%' where user='root';
# 指定用户的授权
mysql > grant all privileges on test.* to root@'%'; #首次会出现错误，多试几次
# 更改数据库登录密钥加签方式
alter user root identified with mysql_native_password by '1234';

注意：

1、在不确定拉下来的 mysql/mysql-server 的版本是，可以先进入容器查看一下版本。

2、这里对数据卷进行了处理。

# mysql 优化配置 经过学习，知道了该mysql服务的数据文件存在“/var/lib/mysql”，我便将其挂载在主机的“/root/work/mysqldata”文件中
docker run --name mysql_2021v2 -e TZ="Asia/Shanghai" -d -p 5306:3306 -v /root/work/mysqldata:/var/lib/mysql  -m 1000M --memory-swap 1200M  -e MYSQL_ROOT_PASSWORD=1234 mysql/mysql-server:8.0.22 

 20220712配置语句

docker run -e TZ="Asia/Shanghai" \
-v /home/mysql/conf:/etc/mysql/conf.d \
-v /home/mysql/data:/var/lib/mysql \
-d -p 3306:3306 \
--name mysql_8_2022  \
-e MYSQL_ROOT_PASSWORD=1234  mysql:latest

mysql8的 my.cnf 配置，位于容器的/etc/mysql/conf.d 里面，其他版本建议参考官方文档再做调整
