Docker安装mysql

1、下载mysql
[root@VM_177_101_centos xieshuang]# docker pull mysql:5.7.18
5.7.18: Pulling from library/mysql
9f0706ba7422: Pull complete

Status: Downloaded newer image for mysql:5.7.18
docker.io/library/mysql:5.7.18
2、启动mysql并挂载数据卷
[root@VM_177_101_centos /]# docker run --restart=always --privileged=true -it -d -p 3306:3306 -v /data/docker/mysql/conf:/etc/mysql/conf.d -v /data/docker/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=dx123456 --name mysql mysql:5.7.18 

启动成功控制台会自动打印容器id,这里可以检查一下容器状态

	[root@VM_177_101_centos /]# docker ps 
	CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
	3e0b9431cdec        mysql:5.7.18        "docker-entrypoint.s…"   35 seconds ago      Up 34 seconds       0.0.0.0:3307->3306/tcp   mysql  

尝试连接一下

[root@VM_177_101_centos src]# mysql -h 127.0.0.1  -P 3307 -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 7
Server version: 5.7.18 MySQL Community Server (GPL)

此时已经连接成功了,也可以通过docker命令docker inspect congtainerId查看挂载内容

"Mounts": [
        {
            "Type": "bind",
            "Source": "/data/docker/mysql/conf",
            "Destination": "/etc/mysql/conf.d",
            "Mode": "",
            "RW": true,
            "Propagation": "rprivate"
        },
        {
            "Type": "bind",
            "Source": "/data/docker/mysql/data",
            "Destination": "/var/lib/mysql",
            "Mode": "",
            "RW": true,
            "Propagation": "rprivate"
        }
    ],

到这里安装过程基本结束,最后再设置一下数据库服务器默认编码格式。

		mysql> show variables like 'charac%';
	+--------------------------+----------------------------+
	| Variable_name            | Value                      |
	+--------------------------+----------------------------+
	| character_set_client     | latin1                     |
	| character_set_connection | latin1                     |
	| character_set_database   | latin1                     |
	| character_set_filesystem | binary                     |
	| character_set_results    | latin1                     |
	| character_set_server     | latin1                     |
	| character_set_system     | utf8                       |
	| character_sets_dir       | /usr/share/mysql/charsets/ |
	+--------------------------+----------------------------+
	8 rows in set (0.01 sec)

在挂载的宿主机目录(/data/docker/mysql/conf/)下新建my.cnf配置文件,内容如下:

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
collation_server = utf8_general_ci
character_set_server = utf8
[client]
default_character_set=utf8
#log-error      = /var/log/mysql/error.log
# By default we only accept connections from localhost
#bind-address   = 127.0.0.1
# Disabling symbolic-links is recommended to prevent assorted security risks
#symbolic-links=0

或者我们通过docker cp命令将容器内的配置文件拷贝出来,然后增加编码设置也可以

docker cp a843b1adb96e:/etc/mysql/mysql.conf.d/mysqld.cnf  /data/docker/mysql/conf/my.cnf

重启容器 docker restart containerId,再查看一下编码是否正常

mysql> show variables like 'charac%';
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | utf8                       |
| character_set_connection | utf8                       |
| character_set_database   | utf8                       |
| character_set_filesystem | binary                     |
| character_set_results    | utf8                       |
| character_set_server     | utf8                       |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)

mysql> exit

好了 剩下可以用navicate等工具连接体验了

那片笑声让我想起我的那些花儿
在我生命每个角落静静为我开着
我曾以为我会永远守在她身旁
今天我们已经离去在人海茫茫
她们都老了吧 她们在哪里呀
幸运的是我曾陪她们开放
