　　gitlab6 nginx配置和启动脚本

　　最近把gitlab安装到了ubuntu12.04.3的虚拟机上了。参考：

　　https://github.com/gitlabhq/gitlabhq/blob/master/doc/install/installation.md
www.nickyeoman.com/blog/system-administration/180-install-gitlab-on-ubuntu

　　

　　我用了2个虚拟机，vm-gitlab6安装gitlab6和相关的东西：nginx, postfix, redis,ruby，另一个vm-mysqldb4git安装了mysql db。用这2台虚拟机构成了整个内网下的 gitlab服务。由于使用了NAT，还需要在主机上安装nginx，指向vm-gitlab6上的nginx服务。
　　虚拟机的用户car设置了sudo免密码，参考：

　　
　　http://blog.csdn.net/cheungmine/article/details/12341005

这样连同主机在内有3台机器：　　--------------------------------------------------

　　host: 192.168.90.122
　　nginx A
　　/etc/hosts 中加入：
　　

192.168.90.122  vm-gitlab
--------------------------------------------------
　　vm-gitlab6: 192.168.122.24
　　nginx B

　　gitlab6.1
　　git

　　ruby2.0x
　　postfix
　　redis
　　-------------------------------------------------

　　vm-mysqldb4git: 192.168.122.139
　　mysqldb for git
　　

　　nginx A需要指向nginx B，nginx A配置文件(/etc/nginx/sites-available/gitlab)如下：

# GITLAB
# Maintainer: @randx
# App Version: 5.0
upstream gitlab {
server unix:/home/git/gitlab/tmp/sockets/gitlab.socket;
}
server {
listen 80;     # e.g., listen 192.168.1.1:80; In most cases *:80 is a good idea
##server_name 192.168.90.122;     # e.g., server_name source.example.com;
server_name 192.168.90.122 vm-gitlab;     # e.g., server_name source.example.com;
server_tokens off;     # don't show the version number, a security best practice
root /home/git/gitlab/public;
# individual nginx logs for this gitlab vhost
access_log  /var/log/nginx/gitlab_access.log;
error_log   /var/log/nginx/gitlab_error.log;
location / {
# serve static files from defined root folder;.
# @gitlab is a named location for the upstream fallback, see below
try_files $uri $uri/index.html $uri.html @gitlab;
}
# if a file, which is not found in the root folder is requested,
# then the proxy pass the request to the upsteam (gitlab unicorn)
location @gitlab {
proxy_read_timeout 300; # https://github.com/gitlabhq/gitlabhq/issues/694
proxy_connect_timeout 300; # https://github.com/gitlabhq/gitlabhq/issues/694
proxy_redirect     off;
proxy_set_header   X-Forwarded-Proto $scheme;
proxy_set_header   Host              $http_host;
proxy_set_header   X-Real-IP         $remote_addr;
proxy_pass http://192.168.122.24;
}
}


nginx B 配置文件(/etc/nginx/sites-available/gitlab)如下：
# GITLAB
# Maintainer: @randx
# App Version: 5.0
upstream gitlab {
server unix:/home/git/gitlab/tmp/sockets/gitlab.socket;
}
server {
listen *:80 default_server;         # e.g., listen 192.168.1.1:80; In most cases *:80 is a good idea
#server_name vm-gitlab;     # e.g., server_name source.example.com;
server_tokens off;     # don't show the version number, a security best practice
root /home/git/gitlab/public;
# individual nginx logs for this gitlab vhost
access_log  /var/log/nginx/gitlab_access.log;
error_log   /var/log/nginx/gitlab_error.log;
location / {
# serve static files from defined root folder;.
# @gitlab is a named location for the upstream fallback, see below
try_files $uri $uri/index.html $uri.html @gitlab;
}
# if a file, which is not found in the root folder is requested,
# then the proxy pass the request to the upsteam (gitlab unicorn)
location @gitlab {
proxy_read_timeout 300;    # https://github.com/gitlabhq/gitlabhq/issues/694
proxy_connect_timeout 300; # https://github.com/gitlabhq/gitlabhq/issues/694
proxy_redirect     off;
proxy_set_header   X-Forwarded-Proto $scheme;
proxy_set_header   Host              $http_host;
proxy_set_header   X-Real-IP         $remote_addr;
proxy_pass http://gitlab;
}
}


由于gitlab都在虚拟机上，每次启动和关闭都很繁琐，特写了启动和关闭的脚本，使操作一键完成，可以重复启动和关闭，这样也方便更改配置。启动脚本如下：　　

#!/bin/bash
# start-gitlab.sh
# cheungmine@gmail.com
################################################################################
# vm-gitlab6

vm_gitlab6_ip='192.168.122.24'

# vm-mysqldb4git
vm_mysqldb4git_name='vm-mysqldb4git'
vm_mysqldb4git_ip='192.168.122.139'
vm_mysqldb4git_login='car'
vm_mysqldb4git_passwd='abc1234'
echo "================================================================="
echo "start gitlab, mysqldb4git virtual machines and services..."
# check if vm-gitlab6 is running
if (! ping -c 1 $vm_gitlab6_ip); then
echo -e $vm_gitlab6_name "(" $vm_gitlab6_ip ") is not running!\r\n"
sudo virsh start $vm_gitlab6_name
fi
# check if vm-mysqldb4git is running
if (! ping -c 1 $vm_mysqldb4git_ip); then
echo -e $vm_mysqldb4git_name "(" $vm_mysqldb4git_ip ") is not running!\r\n"
sudo virsh start $vm_mysqldb4git_name
fi

# waiting for vm-gitlab6 is ready
while (! ping -c 1 $vm_gitlab6_ip); do sleep 1; done
sudo virsh list --all
# start services in vm-gitlab6
sshpass -p $vm_gitlab6_passwd ssh $vm_gitlab6_login@$vm_gitlab6_ip "sudo /etc/init.d/gitlab restart"
sshpass -p $vm_gitlab6_passwd ssh $vm_gitlab6_login@$vm_gitlab6_ip "sudo /etc/init.d/nginx restart"
# start local nginx service
echo "start nginx at localhost:" `hostname`
sudo /etc/init.d/nginx restart
echo "gitlab, mysqldb4git virtual machines and services are now ready !"
echo "================================================================="


关闭脚本如下：

sshpass -p $vm_gitlab6_passwd ssh $vm_gitlab6_login@$vm_gitlab6_ip "sudo /etc/init.d/nginx stop"
sleep 10
sudo virsh shutdown $vm_gitlab6_name
