Centos 6.6上安装Git Lab服务及问题总结

http://www.iyunv.com/thread-97282-1-1.html

cat /etc/issue

CentOS release 6.6 (Final)
Kernel \r on an \m
epel el6 64 位源
rpm –ivh  http://dl.fedoraproject.org/pub/ ... ease-6-8.noarch.rpm


1、初始化安装环境
yum -y groupinstall 'Development Tools'

yum -y install readline readline-devel ncurses-devel gdbm-devel glibc-develtcl-devel openssl-devel curl-devel expat-devel db4-devel byaccsqlite-devel libyaml libyaml-devel libffi libffi-devel libxml2libxml2-devel libxslt libxslt-devel libicu libicu-develsystem-config-firewall-tui crontabs logwatch logrotateperl-Time-HiRes cmakelibcom_err-devel.i686 libcom_err-devel.x86_64 zlib-devel perl-CPANgettext gettext-devel perl-ExtUtils-MakeMaker


2、安装GIT
确保git版本至少在1.7.10或以上，如果不是，卸载重装
yum -y remove git

mkdir /tools/git -p && cd /tools/git
curl --progress  https://www.kernel.org/pub/software/scm/git/git-2.1.3.tar.gz  | tar xz
cd git-2.1.3/
./configure
make
make prefix=/usr/local install
创建软连接
ln -s /usr/local/bin/git /usr/bin/git
git --version

3、安装ruby
注意：请不要用rvm安装ruby，否则，后续会出现一些难以解决的问题
Gitlab7.x需要ruby2.x
如果系统自带的ruby版本低于2.x，就需要升级ruby

yum remove ruby
或者
cd <your-ruby-source-path>
make uninstall

mkdir /tools/ruby && cd /tools/ruby
curl --progress  ftp://ftp.ruby-lang.org/pub/ruby/2.1/ruby-2.1.5.tar.gz  | tar xz
cd ruby-2.1.5
./configure --disable-install-rdoc
make
make prefix=/usr/local install

安装bundler
gem source -r  https://rubygems.org /
gem source -a  http://ruby.taobao.org /
gem install bundler --no-doc


4、添加git账户

useradd -c 'GitLab' git

执行命令：visudo
把/usr/local/bin加入到secure_path里面去
然后，配置git用户可以使用sudo
git ALL=(ALL) ALL


5、安装mysql 

yum install  mysql mysql-devel mysql-server -y
/etc/init.d/mysqld start


mysql_secure_installation
创建gitlab 数据库用户

CREATE USER 'gitlab'@'localhost' IDENTIFIED BY 'gitlab';
CREATE DATABASE IF NOT EXISTS `gitlabhq_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER ON `gitlabhq_production`.* TO 'gitlab'@'localhost';
\q

6、安装redis
mkdir /tools/redis && cd /tools/redis
wget  http://download.redis.io/releases/redis-3.0.3.tar.gz
tar xzf redis-3.0.3.tar.gz
cd redis-3.0.3
make

mkdir -p /usr/local/redis-3.0.3/etc 
mkdir /usr/local/redis-3.0.3/start_script 
/bin/cp -r src /usr/local/redis-3.0.3/ 


vim /usr/local/redis-3.0.3/etc/redis.conf

daemonize yes 
pidfile /data/redisdata/redis6379.pid 
port 6379

logfile /data/redisdata/redis6379.log

set-max-intset-entries 512 
activerehashing yes 
#requirepass admin
bind 0.0.0.0 

mkdir /data/redisdata/ 
ln -s /usr/local/redis-3.0.3/src/redis-* /bin/ 

cd /usr/local/redis-3.0.3/start_script/ 

chmod 744 /usr/local/redis-3.0.3/start_script/redis.sh 
echo "/usr/local/redis-3.0.3/start_script/redis.sh start" >> /etc/rc.local 



7、安装gitlab(使用git用户)
1）
注意，这里必须用git clone下载（在git用户家目录下执行），不要下载网上已经打包好的tar.gz文件，否则以后不能升级
git clone  https://gitlab.com/gitlab-org/gitlab-ce.git  gitlab
cd /home/git/gitlab  (注意目录位置，尽量使用默认的)
然后，切换到需要安装的版本上
这里安装的是v7.9.2
git checkout v7.9.2(注意这里是tag)
git checkout -b v7.9.2

2）复制配置文件
cp config/gitlab.yml.example config/gitlab.yml

修改host 为当前机器的ip地址
sed -i 's|localhost|10.1.7.201|g' config/gitlab.yml

cp config/unicorn.rb.example config/unicorn.rb

3) 授权目录
chmod -R u+rwX public/uploads
chown -R git log tmp/
chmod -R u+rwx log/ tmp/
mkdir /home/git/gitlab-satellites
chmod u+rwx,g=rx,o-rwx /home/git/gitlab-satellites
mkdir tmp/backups

配置数据库访问文件
cp config/database.yml.mysql config/database.yml
编辑config/database.yml，设置其中连接数据库的账号密码

  username: gitlab
  password: "gitlab"

chmod o-rwx config/database.yml

4）配置git的用户和邮件
git config --global user.name "GitLab"
git config --global user.email " [email protected] "
git config --global core.autocrlf input

5）修改Gemfile
vim Gemfile
修改source为  http://ruby.taobao.org

sed -i s# https://rubygems.org # http://ruby.taobao.org #g Gemfile

安装node.js

8、bundle install
bundle install --no-deployment --without development test postgres aws
中途如果不出意外的话，就安装完成（install中途可能要提示输入密码）

如果提示下面的错误：
--------------------------------------------------------------------------------------------
An error occurred while installing charlock_holmes (0.6.9.4), and Bundler cannot continue.
Make sure that `gem install charlock_holmes -v '0.6.9.4'` succeeds before bundling.

gem install charlock_holmes -v '0.6.9.4'

ERROR:  Could not find a valid gem 'charlock_holmes' (= 0.6.9.4), here is why:
          Unable to download data from  https://rubygems.org / - Errno::ECONNRESET: Connection reset by peer - SSL_connect ( https://api.rubygems.org/quick/Marshal.4.8 /charlock_holmes-0.6.9.4.gemspec.rz)
ERROR:  Possible alternatives: charlock_holmes

yum install libicu-devel

--------------------------------------------------------------------------------------------
An error occurred while installing rugged (0.21.4), and Bundler cannot continue.
Make sure that `gem install rugged -v '0.21.4'` succeeds before bundling.

sudo yum -y install cmake
sudo gem install rugged -v '0.21.4'

类似这样的，需要手动安装的gem ,手动安装，然后继续执行上面的bundle install



9、安装GitLab-shell

su - git && cd /home/git
git clone  https://github.com/gitlabhq/gitlab-shell.git
cd gitlab-shell/

通过 git tag 查看最新版本并切换之
git tag
git checkout -b v2.6.3

修改配置文件

cp config.yml.example config.yml
vi config.yml
gitlab_url: " http://git.test.com /"
注意：如果gitlab是使用https访问，则需将http替换成https，配置文件中的self_signed_cert要修改成true，否则gitlab shell在通过api和gitlab进行通信的时候就会出现错误，导致项目push出错。因为后面配置web服务器的时候是使用ssl，所以这里要按照ssl的方式配置。

Tips: 另外如果使用的域名是测试域名，不要忘记在系统的/etc/hosts做域名映射。

安装
./bin/install


10、初始化数据库
bundle exec rake gitlab:setup RAILS_ENV=production
成功的话，会输出
Administrator account created:

login.........root
password......5iveL!fe

记住这里的用户名和密码

--------------------------------------------------------------------------------------------
如果提示下面的错误：
rake aborted!
ExecJS::RuntimeUnavailable: Could not find a JavaScript runtime. See  https://github.com/sstephenson/execjs  for a list of available runtimes.
/home/git/gitlab/config/application.rb:6:in `<top (required)>'
/home/git/gitlab/Rakefile:5:in `require'
/home/git/gitlab/Rakefile:5:in `<top (required)>'
(See full trace by running task with --trace)

sudo yum install nodejs -y


11、检查GitLab及其环境的配置是否正确
git@KVM-7-201 ~/gitlab $ bundle exec rake gitlab:env:info RAILS_ENV=production

System information

GitLab Shell

12、下载启动脚本
sudo wget  https://raw.github.com/gitlabhq/gitlab-recipes/master/init/sysvinit/centos/gitlab-unicorn  -P /etc/init.d/
sudo mv /etc/init.d/gitlab-unicorn /etc/init.d/gitlab
sudo chmod +x /etc/init.d/gitlab
sudo chkconfig --add gitlab
sudo chkconfig gitlab on
sudo /etc/init.d/gitlab start


13、复制配置文件[使用nginx做为WEB服务]
cat  /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl= http://nginx.org/packages/centos /$releasever/$basearch/
gpgcheck=0
enabled=1


sudo yum -y install nginx


sudo cp lib/support/nginx/gitlab /etc/nginx/conf.d/
cd /etc/nginx/conf.d/
sudo chown -R git:git .
cp gitlab gitlab.conf
vi gitlab.conf
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 gitlab.test.com;     # 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;
  client_max_body_size 5m;
  access_log  logs/gitlab_access.log;
  error_log   logs/gitlab_error.log;
  location / {
    try_files $uri $uri/index.html $uri.html @gitlab;
  }
  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_set_header   X-Forwarded-For   $proxy_add_x_forwarded_for;
    proxy_pass  http://gitlab;
  }
}

sudo service nginx restart

14、拉取GitLab静态文件
cd /home/git/gitlab
bundle exec rake assets:precompile RAILS_ENV=production
sudo service gitlab restart


15、访问测试

初始管理员帐号和密码为：
root
5iveL!fe
1）访问gitlab.test.com 如果配置正常会显示如下页面：

 

第一次访问需要修改默认密码
 

登录成功会显示

 

2) 访问如果出现502
 

查看nginx日志，报权限错误
tail /var/log/nginx/gitlab_error.log 

2015/08/07 19:50:31 [crit] 4190#0: *24 connect() to unix:/home/git/gitlab/tmp/sockets/gitlab.socket failed (13: Permission denied) while connecting to upstream, client: 10.190.0.6, server: gitlab.test.com, request: "GET /favicon.ico HTTP/1.1", upstream: " http://unix:/home/git/gitlab/tmp/sockets/gitlab.socket:/502.html ", host: "gitlab.test.com"


解决方案:
chmod 775 /home/git
