Centos 7 docker 安装gogs详解

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
Using default tag: latest
Trying to pull repository docker.io/gogs/gogs ...

[root@localhost ~]# 

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

[root@localhost data]# docker logs --tail 0 -f 712c350adb28cc17b73f0a87548ab97e02f45d0b9bb56c6f6b495de258f01222

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

[root@localhost data]# docker logs --tail 0 -f 712c350adb28cc17b73f0a87548ab97e02f45d0b9bb56c6f6b495de258f01222

可选安装（可自行添加git用户，并分配权限）

yum install zlib-devel perl-CPAN perl-devel curl-devel gettext expat-devel gettext-devel openssl-devel perl-Time-HiRes git -y

注意新建好数据库，且设置好编码和排序集

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

[root@localhost ~]# vim /etc/firewalld/zones/public.xml


  Public
  For use in public areas. You do not trust the other computers on networks to not harm your computer. Only selected incoming connections are accepted.
  
  
  
  
  
  
  
  
  
  
  
  


[root@localhost ~]# firewall-cmd --reload
success
[root@localhost ~]# 

输入安装地址

添加非对称密钥公钥

Administrator@USER-20170324BD MINGW64 ~/Desktop
$ cat ~/.ssh/id_rsa.pub | clip

Administrator@USER-20170324BD MINGW64 ~/Desktop

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！
