docker-compose安装gogs，实现GitHub代码版本管理服务

gogs简介

因为GitHub私服须要钱，因此本身搭建了相似GitHub的代码版本管理系统。

 

docker-compose方式来安装gogs   

经过docker-compose方式来安装gogs，好处是方便管理。如下是从刚装好Centos Linux系统的环境，开始操做：

一、docker环境安装、启动该docker

#docker安装
yum -y install docker-io
#docker启动
service docker start

tip1：若是docker没启动，执行docker ps命令，出现如下问题

“Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?”

执行 service docker start 命令，启动docker服务，便可，可执行docker ps检查

tip2：若是服务器会断电，建议设置docker随Linux启动后自动启动服务，避免服务不可用

systemctl enable docker.service

 

二、docker-compose安装

安装 Docker Compose
#使用命令从Github下载docker-compose可执行程序并到/usr/local/bin目录中，并赋予可执行权限
#下载		
curl -L "https://github.com/docker/compose/releases/download/1.8.1/docker-compose-$(uname -s)-$(uname -m)" > /usr/local/bin/docker-compose
#赋权
chmod +x /usr/local/bin/docker-compose
#执行了上面两个命令，再测试Docker Compose是否工做
docker-compose -v
输出的结果：docker-compose version 1.8.1, build 878cff1

 

三、建gogs目录，配置编排文件

 

[root@localhost docker]# mkdir gogs
[root@localhost docker]# cd gogs/
[root@localhost gogs]# touch docker-compose.yml
[root@localhost gogs]# pwd
/data/docker/gogs

[root@localhost gogs]# cat docker-compose.yml 
gogs:
  image: docker.io/gogs/gogs:latest
  links:
    - mysql-gogs:mysql
  ports:
    - "10022:22"
    - "10080:3000"
  volumes:
    - /opt/docker/gogs/:/data/docker/gogs
  restart: always

mysql-gogs:
  image: docker.io/mysql:5.7.7
  ports:
    - "3306:3306"
  volumes:
    - ./mysql-gogs/mysql:/var/lib/mysql
    - ./mysql-gogs/conf.d:/etc/mysql/conf.d:rw
  environment:
    - MYSQL_DATABASE=gogs
    - MYSQL_USER=gogs
    - MYSQL_PASSWORD=gogs
    - MYSQL_ROOT_PASSWORD=*****
  command: mysqld --lower_case_table_names=1 --character-set-server=utf8mb4 --collation-server=utf8mb4_general_ci
  restart: always

tip1：若是vi编辑文件的时候出现

E325:ATTENTION

这是因为在编辑该文件的时候异常退出了，由于vim在编辑文件时会建立一个交换文件swap file以保证文件的安全性。

解决办法：为了去掉这个警告，咱们须要删除这个swp文件：

rm -f .config.swp

 

tip2：若是有服务层级权限问题，须要调整SELinux状态

[root@localhost mysql]# docker-compose up -d db
Recreating mysql_db_1
WARNING: Service "db" is using volume "/var/lib/mysql" from the previous container. Host mapping "/data/docker/mysql/online_backup/mysql" has no effect. Remove the existing containers (with `docker-compose rm db`) to use the host volume mapping.
[root@localhost mysql]# docker-compose logs -f db

[root@localhost mysql]# getenforce 
Enforcing
[root@localhost mysql]# cat /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
# SELINUXTYPE= can take one of three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted 


[root@localhost mysql]# setenforce 0
[root@localhost mysql]# getenforce 
Permissive

解决后，再reboot服务器，而后重启就OK了

[root@localhost mysql]# reboot
Connection closing...Socket close.

四、启动gogs服务，此处须要注意gogs依赖的数据库必须是utf8编码

[root@localhost gogs]# docker-compose up -d gogs
Creating gogs_mysql-gogs_1
Recreating gogs_gogs_1

启动成功！

 

五、配置gogs

上图圈住的须要注意

 

六、来到这个界面，表示已经搭建好了

七、接下来是gogs基本使用

注册用户  ==》  新建仓库 

 

仓库设置

 

须要把团队成员帐号加入“管理协做者”，不然，他们不能push代码

 

若是不在协做者范围内，会报以下错：

 

如下协助开发项目提交记录

至此，整个gogs搭建完成了

 

接下来继续介绍idea使用git进行项目管理的过程

一、安装git客户端，一直默认安装便可

 

二、安装成功后，随便找个目录能看到

 

三、右键Git Bash Here，设置用户名、密码、密钥

一 设置Git的user name和email
git config --global user.name "xxx"
git config --global user.email "xxx@xxx.com"


二  生成SSH密钥过程
一、查看是否已经有了ssh密钥：cd ~/.ssh
若是没有密钥则不会有此文件夹，有则备份删除。
二、生存密钥
 ssh-keygen -t rsa -C "xxx@xxx.com"

命令执行完后，在~/.ssh目录下会看到id_rsa、id_rsa.pub文件。

四、在gogs页面，用户设置-SSH密钥，而后配置密钥，便可

五、git客户端拉代码

拷贝git地址，而后在git客户端执行clone命令

六、在idea上push代码，如遇如下问题，则按下面方法处理

git报ssh variant 'simple' does not support setting port

解决办法

在git bash中输入命令

git config --global ssh.variant ssh

 

大功告成~
