前言

docker安裝mysql環境非常方便，簡單的幾步操作就可以了

拉取mysql鏡像

先拉取mysql的鏡像，可以在docker的鏡像倉庫找到不同TAG標簽的版本https://hub.docker.com/_/mysql?tab=tags
我這里選擇mysql:5.7標簽

[root@yoyo ~]# docker pull mysql:5.7 5.7: Pulling from library/mysql fc7181108d40: Already exists 787a24c80112: Already exists a08cb039d3cd: Already exists 4f7d35eb5394: Already exists 5aa21f895d95: Already exists a742e211b7a2: Pull complete 0163805ad937: Pull complete 62d0ebcbfc71: Pull complete 559856d01c93: Pull complete c849d5f46e83: Pull complete f114c210789a: Pull complete Digest: sha256:c3594c6528b31c6222ba426d836600abd45f554d078ef661d3c882604c70ad0a Status: Downloaded newer image for mysql:5.7

docker images查看已經下載成功

配置mysql

創建mysql目錄，用于存放mysql相關配置及數據

• mkdir ： 如果存在上級目錄不存在的情況，會無法創建下級目錄, 會提出ERROR
• mkdir -p ：遞歸創建目錄，即使上級目錄不存在，會按目錄層級自動創建目錄
• ~ : ”/“是根目錄，”~“是家目錄。Linux存儲是以掛載的方式，相當于是樹狀的，源頭就是”/“，也就是根目錄。
  而每個用戶都有”家“目錄，也就是用戶的個人目錄，比如root用戶的”家“目錄就是/root,普通用戶a的家目錄就是/home/a

mkdir -p ~/yoyo/mysql/conf ~/yoyo/mysql/data ~/yoyo/mysql/logs

創建完成后，在當前用戶的home目錄(root用戶在root目錄)，會有三個文件夾

[root@yoyo ~]# mkdir -p ~/yoyo/mysql/conf ~/yoyo/mysql/data ~/yoyo/mysql/logs [root@yoyo mysql]# ll ~/yoyo/mysql total 12 drwxr-xr-x 2 root root 4096 Jun 30 10:31 conf drwxr-xr-x 2 root root 4096 Jun 30 10:31 data drwxr-xr-x 2 root root 4096 Jun 30 10:31 logs

運行mysql容器

docker run -p 3309:3306 --name yoyomysql -v ~/yoyo/mysql/conf:/etc/mysql/conf.d -v ~/yoyo/mysql/logs:/logs -v ~/yoyo/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.7

命令說明：

• --name 重命名yoyomysql
• -p 3309:3306：將容器的 3306 端口映射到主機的 3309 端口。
• -v -v ~/yoyo/mysql/conf:/etc/mysql/conf.d：將主機~/yoyo/mysql/conf 掛載到容器的 /etc/mysql/my.cnf。
• -v ~/yoyo/mysql/logs:/logs：將主機~/yoyo/mysql 目錄掛載到容器的 /logs。
• -v ~/yoyo/mysql/data:/var/lib/mysql ：將主機~/yoyo/mysql/data目錄掛載到容器的 /var/lib/mysql 。
• -e MYSQL_ROOT_PASSWORD=123456：初始化 root 用戶的密碼。
• -d 掛后臺運行

啟動完成后，查看運行狀態

[root@yoyo mysql]# docker run -p 3308:3306 --name yoyomysql -v ~/yoyo/mysql/conf:/etc/mysql/conf.d -v ~/yoyo/mysql/logs:/logs -v ~/yoyo/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.7 581137afbd3ba22dc02bf89d3ec1afb6e51d55eed0d99a3a4a979bdee8d5de4a [root@yoyo ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 581137afbd3b mysql:5.7 "docker-entrypoint.s…" 4 minutes ago Up 4 minutes 33060/tcp, 0.0.0.0:3309->3306/tcp yoyomysql

查看~/yoyo/mysql/data目錄會看到有數據

[root@yoyo ~]# ll ~/yoyo/mysql/data/ total 188476 -rw-r----- 1 polkitd ssh_keys 56 Jun 30 10:38 auto.cnf -rw------- 1 polkitd ssh_keys 1679 Jun 30 10:38 ca-key.pem -rw-r--r-- 1 polkitd ssh_keys 1107 Jun 30 10:38 ca.pem -rw-r--r-- 1 polkitd ssh_keys 1107 Jun 30 10:38 client-cert.pem -rw------- 1 polkitd ssh_keys 1675 Jun 30 10:38 client-key.pem -rw-r----- 1 polkitd ssh_keys 1340 Jun 30 10:38 ib_buffer_pool -rw-r----- 1 polkitd ssh_keys 79691776 Jun 30 10:38 ibdata1 -rw-r----- 1 polkitd ssh_keys 50331648 Jun 30 10:38 ib_logfile0 -rw-r----- 1 polkitd ssh_keys 50331648 Jun 30 10:38 ib_logfile1 -rw-r----- 1 polkitd ssh_keys 12582912 Jun 30 10:38 ibtmp1 drwxr-x--- 2 polkitd ssh_keys 4096 Jun 30 10:38 mysql drwxr-x--- 2 polkitd ssh_keys 4096 Jun 30 10:38 performance_schema -rw------- 1 polkitd ssh_keys 1679 Jun 30 10:38 private_key.pem -rw-r--r-- 1 polkitd ssh_keys 451 Jun 30 10:38 public_key.pem -rw-r--r-- 1 polkitd ssh_keys 1107 Jun 30 10:38 server-cert.pem -rw------- 1 polkitd ssh_keys 1675 Jun 30 10:38 server-key.pem drwxr-x--- 2 polkitd ssh_keys 12288 Jun 30 10:38 sys

進入容器bash

輸入docker exec -it mysql bash進入容器bash,接著輸入mysql -uroot -p輸入root用戶密碼123456進入mysql

[root@yoyo data]# docker exec -i -t yoyomysql bash root@581137afbd3b:/# mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

進入mysql之后所有指令結尾都需要 ;

• show databases; 查看所有的庫
• use 某個數據庫, 如 use mysql;
• select 查詢語句;

mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | sys | +--------------------+ 4 rows in set (0.00 sec)mysql> use mysql; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -ADatabase changed mysql> select host, user from user; +-----------+---------------+ | host | user | +-----------+---------------+ | % | root | | localhost | mysql.session | | localhost | mysql.sys | | localhost | root | +-----------+---------------+ 4 rows in set (0.00 sec)mysql> exit Bye root@581137afbd3b:/# exit exit

退出mysql和容器用exit
