Docker下部署安装Mysql

1.拉取镜像

# 拉取最新版本
docker pull mysql
# 拉取指定版本号
docker pull mysql:版本号

2.在宿主机创建文件夹，易于管理Mysql配置文件等（当前目录在根目录下/data下），创建mysql目录并创建conf、data目录

mkdir -p /data/mysql && cd $_ && mkdir {conf,data}

3.创建配置文件my.cnf

wait_timeout=120
interactive_timeout=300lower_case_table_names=1 # unix默认是0，windows默认是1，mac是2 0是区分大小写的，1是不区分的，也就是windows是默认不区分大小写的。

4.创建mysql容器

docker run --restart=always -d --name webmysql -p xxxx:3306 -v /web-data/data/mysql/mysql/conf/my.cnf:/etc/mysql/my.cnf -v /web-data/data/mysql/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=Aini.52070 mysql

参数说明：
–restart=always ：自动重启；
-d：守护进程；
–name webmysql：修改映射的名称；
-p xxxx:3306：端口映射，宿主机：docker下；
-v /web-data/data/mysql/mysql/conf/my.cnf:/etc/mysql/my.cnf ：宿主机地址：docker下配置
-v /web-data/data/mysql/mysql/data:/var/lib/mysql ：宿主机数据位置：docker下数据位置
-e MYSQL_ROOT_PASSWORD=xxxx ：设置密码
mysql ：docker引入的mysql名称

5.docker下可能需要用到的命令

# 进入docker下mysql容器
docker exec -it webmysql /bin/bash# 查看指定容器日志
docker logs -f --tail 查看的数量 容器id# 查看所有容器
docker ps -a# 删除创建的容器
docker rm 容器id# 重启容器
docker restart 容器名/容器id
