podman安装mysql容器
前言
mysql如果正式安装，卸载起来比较麻烦。如果是自己测试用的话，可以用podman拉取一个镜像来使用。
这里使用的是mysql5.7版本，对应的docker镜像是mysql:5.7
(如果拉取较慢，可以选择使用阿里云镜像源：j3m2itm3.mirror.aliyuncs.com)
这篇随笔主要参考博客podman安装mysql
正文
- 拉取mysql镜像
podman pull mysql:5.7
拉取完毕后，可以通过如下指令查看镜像
podman images
# REPOSITORY TAG IMAGE ID CREATED SIZE
# docker.io/library/mysql 5.7 c20987f18b13 9 months ago 454 MB
- 建立本地映射文件
mkdir mysql5.7
cd mysql5.7
mkdir conf
mkdir data
mkdir log
- 新建my.cnf
cd conf
touch my.cnf
编辑my.cnf如下
(无耻抄一下上面的博客!

mysql8.4 新特性 MySQL 8.4新特性速览
# 从 MySQL 8.4.0 开始，mysql_native_password 认证插件默认不再启用。
# 若要启用，需要在MySQL启动的时候，添加--mysql-native-password=ON 参数；
# 或在配置文件中设置 mysql_native_password=ON。
- 在mysql5.7中新建启动脚本
mysql_ctl.sh
#!/bin/bash
container_name=mysql5.7
file_path=/home/brian/podman/mysql/mysql5.7
function start()
{
podman run -itd --rm \
-p 3306:3306 \
-e MYSQL_ROOT_PASSWORD=root \
-v $file_path/data:/var/lib/mysql:rw \
-v $file_path/log:/var/log/mysql:rw \
-v $file_path/conf/my.cnf:/etc/mysql/my.cnf:rw \
-v /etc/localtime:/etc/localtime:ro \
--name $container_name \
mysql:5.7
}
function debug()
{
podman run -it --rm \
-p 3306:3306 \
-e MYSQL_ROOT_PASSWORD=root \
-v $file_path/data:/var/lib/mysql:rw \
-v $file_path/log:/var/log/mysql:rw \
-v $file_path/conf/my.cnf:/etc/mysql/my.cnf:rw \
-v /etc/localtime:/etc/localtime:ro \
--name $container_name \
mysql:5.7
}
function stop()
{
podman stop $container_name
}
function podman_ps()
{
podman ps -a
}
function login()
{
podman exec -it $container_name bash
}
function mysql_in()
{
podman exec -it mysql8 mysql -uroot -p
}
function usage()
{
echo -e "Usage: $0 start|debug|stop|ps|login|mysql_in"
exit 0
}
if [[ $1 == "start" ]];then
start
elif [[ $1 == "debug" ]];then
debug
elif [[ $1 == "stop" ]];then
stop
elif [[ $1 == "ps" ]];then
podman_ps
elif [[ $1 == "login" ]];then
login
elif [[ $1 == "mysql_in" ]];then
mysql_in
else
usage
fi
- 脚本使用
chmod +x mysql_ctl.sh
# 后台启动
./mysql_ctl.sh start
# 非后台启动(用于debug)
# 停止的话需要新建终端，使用 podman stop mysql5.7, 或脚本的stop
./mysql_ctl.sh debug
# 停止
# (因为启动时添加了参数--rm,容器一停止立马自动删除)
./mysql_ctl.sh stop
# 查看所有启动的容器
./mysql_ctl.sh ps
# 登录进容器
./mysql_ctl.sh login
- 配置root远程登录
这个环境中，mysql的root用户的默认密码为root
# 启动容器后，登录进容器
./mysql_ctl.sh login
# 登录mysql
mysql -uroot -p
# 输入默认密码：root
# 如果是mysql:5.7配置root远程登录
alter user 'root'@'%' identified with mysql_native_password by '密码';
FLUSH PRIVILEGES;
# 如果是mysql8, 好像mysql8.4改为使用插件:caching_sha2_password
ALTER USER 'root'@'%' IDENTIFIED BY '密码';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
