阿里Centos安裝mysql

 

最近使用阿里雲服務器安裝mysql遇到的一些問題，在此記錄下。

安裝mysql首先要在阿里雲服務器設置頁面裏面打開3306對應的端口號。

在裏面打開對應的端口號開發，也能夠自定義端口號，建立時能夠選擇。阿里雲安全防護級別比較高，若是要遠程訪問mysql服務器，就必須對指定的ip地址進行受權，每一條規則只能設定一個ip號，一樣的服務如mysql想要受權多個ip地址，就須要克隆設置多個ip地址就行。若是不進行端口號受權，遠程訪問是訪問不了的！

下面來介紹下利用docker安裝mysql。這裏就不介紹docker的安裝方法了，你們能夠去菜鳥網學習安裝。

進入到服務器，首先輸入docker search mysql查看下當前docker中有的mysql鏡像，用以選擇下載。

如上所示，能夠看到各類版本，在這裏咱們選擇mysql 5.7版原本進行安裝。

從docker拉取mysql鏡像，docker pull mysql:5.7，固然你也能夠選擇5.6版本，只要選擇對應版本號替換就行。

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

 

而後輸入docker images |grep mysql 查看mysql安裝狀況，顯示以下：

1 [root@iZwz9a191mdam4di3dozk3Z mysql]# docker images |grep mysql 2 mysql                5.7                 a46c2a2722b9        4 days ago          256MB

建立mysql，輸入docker create -it mysql:5.7安裝mysql，而後輸入docker run --name mysqlserver -e MYSQL_ROOT_PASSWORD=password -d -i -p 3306:3306 mysql:5.7，運行mysql並設置密碼。

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輸入，docker ps，顯示以下：

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

而後執行：docker exec -it e061047acf6e /bin/bash

1 [root@iZwz9a191mdam4di3dozk3Z mysql]# docker exec -it e061047acf6e /bin/bash

「e061047acf6e」是上面CONTAINER ID，對應的mysql:5.7的鏡像。
執行以後鏈接mysql，輸入：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

13 Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

輸入密碼以後就能看到鏈接進入了mysql客服端了，就表示一切ok了。外網遠程訪問時就能夠鏈接了。

利用軟件工具遠程鏈接服務器中的mysql，輸入服務器ip以及帳號密碼就好了。至於mysql用戶名受權什麼的，能夠查看相關mysql的文檔。
