GitLab升级到5.1注意事项

1. GitLab-Shell仍然需要正确配置才能访问GitLab，否则你在远端用git协议pull的时候会看到错误信息：

git pull
/usr/local/lib/ruby/1.9.1/net/http.rb:762:in `initialize': Connection refused - connect(2) (Errno::ECONNREFUSED)
	from /usr/local/lib/ruby/1.9.1/net/http.rb:762:in `open'
	from /usr/local/lib/ruby/1.9.1/net/http.rb:762:in `block in connect'
	from /usr/local/lib/ruby/1.9.1/timeout.rb:54:in `timeout'
	from /usr/local/lib/ruby/1.9.1/timeout.rb:99:in `timeout'
	from /usr/local/lib/ruby/1.9.1/net/http.rb:762:in `connect'
	from /usr/local/lib/ruby/1.9.1/net/http.rb:755:in `do_start'
	from /usr/local/lib/ruby/1.9.1/net/http.rb:744:in `start'
	from /home/git/gitlab-shell/lib/gitlab_net.rb:56:in `get'
	from /home/git/gitlab-shell/lib/gitlab_net.rb:17:in `allowed?'
	from /home/git/gitlab-shell/lib/gitlab_shell.rb:51:in `validate_access'
	from /home/git/gitlab-shell/lib/gitlab_shell.rb:21:in `exec'
	from /home/git/gitlab-shell/bin/gitlab-shell:16:in `<main>'

或者这种错误：

git pull
/usr/local/lib/ruby/1.9.1/net/http.rb:799:in `connect': SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (OpenSSL::SSL::SSLError)
	from /usr/local/lib/ruby/1.9.1/net/http.rb:799:in `block in connect'
	from /usr/local/lib/ruby/1.9.1/timeout.rb:54:in `timeout'
	from /usr/local/lib/ruby/1.9.1/timeout.rb:99:in `timeout'
	from /usr/local/lib/ruby/1.9.1/net/http.rb:799:in `connect'
	from /usr/local/lib/ruby/1.9.1/net/http.rb:755:in `do_start'
	from /usr/local/lib/ruby/1.9.1/net/http.rb:744:in `start'
	from /home/git/gitlab-shell/lib/gitlab_net.rb:56:in `get'
	from /home/git/gitlab-shell/lib/gitlab_net.rb:17:in `allowed?'
	from /home/git/gitlab-shell/lib/gitlab_shell.rb:51:in `validate_access'
	from /home/git/gitlab-shell/lib/gitlab_shell.rb:21:in `exec'
	from /home/git/gitlab-shell/bin/gitlab-shell:16:in `<main>'

通过查看/home/git/gitlab-shell/lib/gitlab_net.rb文件的代码可以看到这段：

    http.use_ssl = (url.scheme == 'https')

    if config.http_settings['self_signed_cert'] && http.use_ssl?
      http.verify_mode = OpenSSL::SSL::VERIFY_NONE
    end

两个条件：

1.self_signed_cert设置为true

2.url要用https

回到config.yml文件中，这样配置：

# Url to gitlab instance. Used for api calls. Should be ends with slash.                                                                                                                                             
gitlab_url: "https://localhost/"

http_settings:
#  user: someone                                                                                                                                                                                                     
#  password: somepass                                                                                                                                                                                                
  self_signed_cert: true

第一个问题搞定。

2. 重启时老看到这个错误：

* Listening on unix:///home/git/gitlab/tmp/sockets/gitlab.socket
/home/git/gitlab/vendor/bundle/ruby/1.9.1/gems/puma-2.0.0.b7/lib/puma/binder.rb:234:in `initialize': Address already in use - /home/git/gitlab/tmp/sockets/gitlab.socket (Errno::EADDRINUSE)

	from /home/git/gitlab/vendor/bundle/ruby/1.9.1/bin/puma:23:in `<main>'

处理方法：

1.先用ps-def | grep gitlab 命令找到还运行的进程id，然后kill -9 干掉

2.删除下面的文件

/home/git/gitlab/tmp/sockets/gitlab.socket

现在启动，应该可以了。
