docker-compose安裝gogs，實現GitHub代碼版本管理服務

gogs簡介

因爲GitHub私服須要錢，因此本身搭建了相似GitHub的代碼版本管理系統。

 

docker-compose方式來安裝gogs   

經過docker-compose方式來安裝gogs，好處是方便管理。如下是從剛裝好Centos Linux系統的環境，開始操做：

一、docker環境安裝、啓動該docker

#docker安裝
yum -y install docker-io
#docker啓動
service docker start

tip1：若是docker沒啓動，執行docker ps命令，出現如下問題

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

執行 service docker start 命令，啓動docker服務，便可，可執行docker ps檢查

tip2：若是服務器會斷電，建議設置docker隨Linux啓動後自動啓動服務，避免服務不可用

systemctl enable docker.service

 

二、docker-compose安裝

安裝 Docker Compose
#使用命令從Github下載docker-compose可執行程序併到/usr/local/bin目錄中，並賦予可執行權限
#下載		
curl -L "https://github.com/docker/compose/releases/download/1.8.1/docker-compose-$(uname -s)-$(uname -m)" > /usr/local/bin/docker-compose
#賦權
chmod +x /usr/local/bin/docker-compose
#執行了上面兩個命令，再測試Docker Compose是否工做
docker-compose -v
輸出的結果：docker-compose version 1.8.1, build 878cff1

 

三、建gogs目錄，配置編排文件

 

[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編輯文件的時候出現

E325:ATTENTION

這是因爲在編輯該文件的時候異常退出了，由於vim在編輯文件時會建立一個交換文件swap file以保證文件的安全性。

解決辦法：爲了去掉這個警告，咱們須要刪除這個swp文件：

rm -f .config.swp

 

tip2：若是有服務層級權限問題，須要調整SELinux狀態

[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

解決後，再reboot服務器，而後重啓就OK了

[root@localhost mysql]# reboot
Connection closing...Socket close.
[root@localhost mysql]# docker-compose up -d db

[root@localhost mysql]# docker-compose logs -f db

四、啓動gogs服務，此處須要注意gogs依賴的數據庫必須是utf8編碼

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

啓動成功！

 

五、配置gogs

上圖圈住的須要注意

 

六、來到這個界面，表示已經搭建好了

七、接下來是gogs基本使用

註冊用戶  ==》  新建倉庫 

 

倉庫設置

 

須要把團隊成員帳號加入「管理協做者」，不然，他們不能push代碼

 

若是不在協做者範圍內，會報以下錯：

 

如下協助開發項目提交記錄

至此，整個gogs搭建完成了

 

接下來繼續介紹idea使用git進行項目管理的過程

一、安裝git客戶端，一直默認安裝便可

 

二、安裝成功後，隨便找個目錄能看到

 

三、右鍵Git Bash Here，設置用戶名、密碼、密鑰

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


二  生成SSH密鑰過程
一、查看是否已經有了ssh密鑰：cd ~/.ssh
若是沒有密鑰則不會有此文件夾，有則備份刪除。
二、生存密鑰
 ssh-keygen -t rsa -C "xxx@xxx.com"

命令執行完後，在~/.ssh目錄下會看到id_rsa、id_rsa.pub文件。

四、在gogs頁面，用戶設置-SSH密鑰，而後配置密鑰，便可

五、git客戶端拉代碼

拷貝git地址，而後在git客戶端執行clone命令

六、在idea上push代碼，如遇如下問題，則按下面方法處理

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

解決辦法

在git bash中輸入命令

git config --global ssh.variant ssh

 

大功告成~
