安装前提提交
系统版本为3.10.0以上才能安装
[root@localhost conf]# uname -a
Linux localhost.localdomain 3.10.0-693.11.1.el7.x86_64 #1 SMP Mon Dec 4 23:52:40 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost conf]#
安装mysql
docker pull mysql/mysql-server:latest
docker run -d --restart always -e MYSQL_ROOT_PASSWORD=123456 --name mysql -v $PWD/mysql/my.cnf:/etc/mysql/my.cnf -v $PWD/mysql/data:/var/lib/mysql -p 3306:3306 mysql/mysql-server:latest
docker exec -it ce33e66bd8a5 /bin/sh
mysql -uroot -p -h localhost
修改 mysql密码及授权登录
修改本地root用户密码，并开放root远程访问权限
set password for root@localhost = password('123456');
grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;
FLUSH PRIVILEGES;
本地化数据
Docker mysql 把数据存储在本地目录，很简单，只需要映射本地目录到容器即可
1、加上-v参数
$ docker run -d -e MYSQL_ROOT_PASSWORD=123456 --name mysql -v /data/mysql/data:/var/lib/mysql -p 3306:3306 mysql
还可以指定配置文件
docker run -d -e MYSQL_ROOT_PASSWORD=123456 --name mysql -v /data/mysql/my.cnf:/etc/mysql/my.cnf -v /data/mysql/data:/var/lib/mysql -p 3306:3306 mysql
这样，即可修改配置文件，还能把数据存在本地目录，一举两得，-v 参数可以多次使用，每次映射一个目录，通过这种方式，很容易进行配置。
安装gogs镜像
[root@localhost ~]# docker pull gogs/gogs

运行gogs镜像
docker run -d --name=mygogs -p 2222:22 -p 9090:3000 -v /srv/gogs:/data gogs/gogs
常见问题
监听日志，提示没有权限
mkdir: can't create directory '/data/git/': Permission denied
此时，可能是SELINUX阻止的原因

关闭SELINUX即可解决
(1)临时关闭：setenforce 0
(2)永久关闭： vim /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
#SELINUX=enforcing
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
再次监听日志运行成功

提示数据库设置不正确：dial tcp 192.168.0.18:3306: getsockopt: no route to host
设置好防火墙即可

如遇配置不一致
修改/srv/gogs/gogs/conf其中的配置即可
[root@localhost conf]# pwd
/srv/gogs/gogs/conf
[root@localhost conf]#
[root@localhost conf]# vim app.ini
[root@localhost conf]#

至此，gogs安装完毕！
