之前一篇随笔《Docker Centos安装Openssh》 写的是如何在基础的centos镜像中搭建ssh服务，在此基础上再搭建其他服务。本文继续介绍在centos_ssh基础上搭建mysql服务。
1、启动centos_sshd镜像
# docker run --net=host -d registry:5000/centos-sshd-222:v1.0 /run.sh
这里用的是host模式连接的网络，启动之后即可通过ssh登录到容器内部，装上mysql之后可以直接重启容器来验证是否成功。
2、安装mysql
# yum install wget -y # wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm # rpm -ivh mysql-community-release-el7-5.noarch.rpm # yum install mysql-community-server
3、配置
# mysql_install_db --user=mysql --ldata=/var/lib/mysql
4、开启mysql
# mysqld_safe
5、配置root用户密码、赋予root远程连接权限
再开一个终端，进入mysql，执行如下命令：
# mysql -u root mysql> UPDATE mysql.user SET Password = PASSWORD(‘123456‘) WHERE User = ‘root‘; mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘123456‘ WITH GRANT OPTION; mysql> flush privileges;
6、更改mysql配置，使服务忽略大小写、以utf8传输等
# vi /etc/my.cnf # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html [client] default-character-set=utf8 [mysqld] # # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M # # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin # # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M lower_case_table_names=1 datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql max_allowed_packet=20M # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 character-set-server=utf8 init_connect=‘SET NAMES utf8‘ sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES [mysql] default-character-set=utf8 # Disabling symbolic-links is recommended to prevent assorted security risks #symbolic-links=0 # Recommended in standard MySQL setup #sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid
7、更改启动脚本
[root@localhost /]# vi /run.sh #!/bin/bash mkdir /var/run/mysqld chgrp mysql /var/run/mysqld/ chmod g+w /var/run/mysqld/ /usr/sbin/sshd mysqld_safe
8、重启容器
[root@localhost home]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 9766bd087945 registry:5000/centos-sshd-222:v1.0 "/run.sh" 38 minutes ago Up 36 seconds hopeful_hawking [root@localhost home]# docker restart 9766bd087945 9766bd087945
9、验证mysql，在其余安装了mysql的服务器上执行：
[root@localhost home]# mysql -u root -p123456 -h192.168.31.203 Welcome to the MySQL monitor. Commands end with ; or \g.

Type ‘\c‘ to clear the current input statement. mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | +--------------------+ 3 rows in set (0.00 sec) mysql>
10、提交至docker镜像，该步骤在《Docker Centos安装Openssh》中提到过，敬请移步至该文章。
