Docker DevOps（一）

安裝Git和MySql構建持續整合的版本控制和資料庫環境

1.安裝docker

安裝docker，docker源自行配置

[root@mywang ~]# yum  -y install docker-ce

開啟 iptables轉發功能

[root@mywang ~]# cat /etc/sysctl.conf 
# sysctl settings are defined through files in
# /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.
#
# Vendors settings live in /usr/lib/sysctl.d/.
# To override a whole file, create a new file with the same in
# /etc/sysctl.d/ and put new settings there. To override
# only specific settings, add a file with a lexically later
# name in /etc/sysctl.d/ and put new settings there.
#
# For more information, see sysctl.conf(5) and sysctl.d(5).
​
net.ipv4.ip_forward = 1
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
[root@mywang ~]# modprobe br_netfilter
[root@mywang ~]# sysctl -p
net.ipv4.ip_forward = 1
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
 

啟動並設定開機自啟

[root@mywang ~]# systemctl start docker
[root@mywang ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

2.拉取映象

拉取映象

[root@mywang ~]# docker pull gogs/gogs && docker pull mysql

啟動容器

[root@mywang ~]# docker run -itd -p 81:3000 --name=gogs gogs/gogs:latest
c16a482e29617b5f91b75693952f53443da81f70eb159383695aee43bd6514a7
[root@mywang ~]# docker run -itd -p 13306:3306 -e MYSQL_ROOT_PASSWORD=123 --name=gogs-mysql mysql
0735ae246113ebd61cdf9be7a90e73d241b8ff9d1ce4aa81f7c46a466556e626

3.建立資料庫

進入容器，建立資料庫gogs

[root@mywang ~]# docker exec -it gogs-mysql /bin/bash
root@0735ae246113:/# mysql -u root -p
Enter password:

​
mysql> create database gogs;

​
mysql> show databases;

​
mysql> exit
Bye
​

在網頁登入gogs服務 ，配置資料庫資訊，點選安裝

##建議將域名和應用url改成自己終端的ip，不然網頁會跳轉到宿主機的http://localhost:81/user/login

進行使用者註冊並登入

建立新的倉庫

安裝git，複製Git庫到本地/opt目錄，構建私有倉庫。

[root@mywang opt]# yum -y install git

[root@mywang opt]# git clone http://10.66.48.37:81/root/repository01.git
Cloning into 'repository01'...
warning: You appear to have cloned an empty repository.
[root@mywang opt]#
