阿里Centos安装mysql
最近使用阿里云服务器安装mysql遇到的一些问题，在此记录下。
安装mysql首先要在阿里云服务器设置页面里面打开3306对应的端口号。
在里面打开对应的端口号开发，也可以自定义端口号，创建时可以选择。阿里云安全防御级别比较高，如果要远程访问mysql服务器，就必须对指定的ip地址进行授权，每一条规则只能设定一个ip号，同样的服务如mysql想要授权多个ip地址，就需要克隆设置多个ip地址就行。如果不进行端口号授权，远程访问是访问不了的！
下面来介绍下利用docker安装mysql。这里就不介绍docker的安装方法了，大家可以去菜鸟网学习安装。
进入到服务器，首先输入docker search mysql查看下当前docker中有的mysql镜像，用以选择下载。

如上所示，可以看到各种版本，在这里我们选择mysql 5.7版本来进行安装。
从docker拉取mysql镜像，docker pull mysql:5.7，当然你也可以选择5.6版本，只要选择对应版本号替换就行。
1[root@iZwz9a191mdam4di3dozk3Z /]# docker pull mysql:5.7
1 5.7: Pulling from library/mysql 2 f17d81b4b692: Pull complete 3 c691115e6ae9: Pull complete 4 41544cb19235: Pull complete 5 254d04f5f66d: Pull complete 6 4fe240edfdc9: Pull complete 7 b79c3b745cc6: Pull complete 8 c6ebcbee59b1: Pull complete 9 e9bb65297d95: Pull complete 10 2a7c8492496e: Pull complete 11 6af69434adbe: Pull complete 12 54bc8b20381b: Pull complete 13 Digest: sha256:b56c3109f09a90c045ebe991e085fcaab5008cd6dbb8ab5ad1d6101fc0f87fcf 14 Status: Downloaded newer image for mysql:5.7
然后输入docker images |grep mysql 查看mysql安装情况，显示如下：
1 [root@iZwz9a191mdam4di3dozk3Z mysql]# docker images |grep mysql 2 mysql 5.7 a46c2a2722b9 4 days ago 256MB
创建mysql，输入docker create -it mysql:5.7安装mysql，然后输入docker run --name mysqlserver -e MYSQL_ROOT_PASSWORD=password -d -i -p 3306:3306 mysql:5.7，运行mysql并设置密码。
1 [root@iZwz9a191mdam4di3dozk3Z mysql]# docker create -it mysql:5.7 2 61c7a4d6363defac673461bb842685302dbe894f96c6dee03f2539de4af2a5d6 3 [root@iZwz9a191mdam4di3dozk3Z mysql]# docker run --name mysqlserver -e MYSQL_ROOT_PASSWORD=sgcc -d -i -p 3306:3306 mysql:5.7 4 e061047acf6e99ca72c22743ee727f708c129cdc8c5628c25e59253db4069ba6
查看mysql输入，docker ps，显示如下：
1 [root@iZwz9a191mdam4di3dozk3Z mysql]# docker ps 2 CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3 e061047acf6e mysql:5.7 "docker-entrypoint.s…" 13 seconds ago Up 12 seconds 0.0.0.0:3306->3306/tcp mysqlserver 4 024c06fcc1e8 morunchang/fastdfs "sh storage.sh" 3 days ago Up 3 days storage 5 3f2da1b259b5 morunchang/fastdfs "sh tracker.sh" 3 days ago Up 3 days
然后执行：docker exec -it e061047acf6e /bin/bash
1 [root@iZwz9a191mdam4di3dozk3Z mysql]# docker exec -it e061047acf6e /bin/bash
“e061047acf6e”是上面CONTAINER ID，对应的mysql:5.7的镜像。
执行之后连接mysql，输入：mysql -h 127.0.0.1 -u root -p
1 root@e061047acf6e:/# mysql -h 127.0.0.1 -u root -p 2 Enter password: 3 Welcome to the MySQL monitor. Commands end with ; or \g. 4 Your MySQL connection id is 3 5 Server version: 5.6.42 MySQL Community Server (GPL) 6 7 Copyright (c) 2000, 2018, Oracle and/or its affiliates.

输入密码之后就能看到连接进入了mysql客服端了，就表示一切ok了。外网远程访问时就可以连接了。
利用软件工具远程连接服务器中的mysql，输入服务器ip以及账号密码就行了。至于mysql用户名授权什么的，可以查看相关mysql的文档。
