docker 安装mysql_Docker安装MySQL完整版流程

我们自己在linux上安装mysql的话，超级麻烦，安装完后还要进行各种各样的配置，之前在docker专题写了用docker安装mysql的快速版本以及修改编码的方式，这里总结一下安装流程和命令。

环境

Linux version 3.10.0-693.2.2.el7.x86_64

docker18.09.2

mysql5.7

安装流程命令

下面我直接快速的说明安装流程和命令，包括中文编码问题的解决。

1、拉取镜像docker pull mysql:5.7

2、创建配置和数据挂载点mkdir-p/data/mysql/data3309

mkdir-p/data/mysql/mysql.conf.d3309

这里启动的容器端口为3309,所以直接命名为3309

3、编写配置文件

新建名称为mysqld.cnf的配置文件,访入/data/mysql/mysql.conf.d3309/目录下，内容如下，目的是覆盖掉容器内的配置文件，好修改编码格式为utf_8,而不是参照网上的进入容器中修改。

[mysqld]

pid-file=/var/run/mysqld/mysqld.pid

socket=/var/run/mysqld/mysqld.sock

datadir=/var/lib/mysql

#innodb_buffer_pool_size = 50M

#ngram_token_size=1

#ft_min_word_len=3

#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

[client]

default-character-set=utf8

[mysql]

default-character-set=utf8

顺便说下，里面的这些配置，其实跟mysql的快速安装没有关系。主要是加上设置编码的内容，就是后面两句

[client]

default-character-set=utf8

[mysql]

default-character-set=utf8innodb_buffer_pool_size默认是128M

ngram_token_size默认分词是2，用于全文索引中文分词

ft_min_word_len默认值是4，只有四个字母的单词才会建立全文索引

4、创建mysql容器

这里创建的容器端口为3309，root密码为123456，数据和配置文件挂载点用上面创建的目录，设置编码格式为utf8mb4

docker create--name mysql3308-v/data/mysql/data3309:/var/lib/mysql-v/data/mysql/mysql.conf.d3309/mysqld.cnf:/etc/mysql/mysql.conf.d/mysqld.cnf-e MYSQL_ROOT_PASSWORD=123456-p3309:3306mysql:5.7--character-set-server=utf8mb4--collation-server=utf8mb4_unicode_ci

5、启动容器

docker start mysql3309

6、测试容器

首先进入到容器

dockerexec-it mysql3309 bash

然后用如下命令登录,当然也可以省去-h127.0.0.1

mysql-h127.0.0.1-uroot-p123456

若是进入到mysql命令行界面就表明安装成功

7、新建另一个mysql容器

只需要新建挂载点然后执行创建mysql容器命令即可。(注意端口号的修改)

8、一些操作命令docker stop mysql3309#停止容器

docker start mysql3309#启动容器
