使用docker部署nginx+tomcat架构(2)：访问mysql数据库

上一篇完成了通过docker部署nginx+tomcat的基础软件架构，但是距离一个真正可用的软件架构还差得很远。其中最重要的一点是缺少数据库这个角色的存在，那么本篇就来完善这一点。

废话少说，直接进入正题。

首先拉取mysql镜像：

docker pull mysql:5.7

创建本地mysql目录：

mkdir -p ~/mysql/data ~/mysql/conf ~/mysql/logs
chmod -R 777 ~/mysql/logs

在mysql/conf目录下创建配置文件my.cnf：

# For advice on how to change settings please see

# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html

[mysqld]

#

# Remove leading # and set to the amount of RAM for the most important data

# cache in MySQL. Start at % of total RAM for dedicated server, else %.

# 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

datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=

log-error=/var/log/mysql/error.log

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

# disabling the password validation

#validate_password=off

# set bind-address

#bind-address=0.0.0.0

启动mysql：

docker run -d -p : --name mysql -e MYSQL_ROOT_PASSWORD=admin -v ~/mysql/conf:/etc/mysql/conf.d -v ~/mysql/data:/var/lib/mysql -v ~/mysql/logs:/var/log/mysql mysql:5.7

登录mysql测试下（root密码已经已经设置成了admin）：

mysql -uroot -p -h 172.17.0.2

看上去没什么问题
