gitlab基本配置

注：是否配置https、相对路径/gitlab根据实际情况

1、gitlab.yml

cd /home/git/gitlab
vim config/gitlab.yml
编辑如下：
第32行
gitlab:
    ## Web server settings (note: host is the FQDN, do not include http://)
    host:domain
    port: 443 
    https: ture 

第47行
relative_url_root: /gitlab

2、unicorn.rb
cd /home/git/gitlab
执行如下命令查看CPU内核数
nproc
vim config/unicorn.rb
修改如下:
ENV['RAILS_RELATIVE_URL_ROOT'] = "/gitlab"
worker_processes 4

3、resque.yml
cd /home/git/gitlab
vim config/resque.yml
修改如下：
production:
# Redis (single instance)
url: redis://:pass@host:6379/db

4、database.yml
cd /home/git/gitlab
vim config/database.yml
修改如下：
production:
adapter: mysql2
encoding: utf8
collation: utf8_general_ci
reconnect: false
database: db
pool: 10
username: un
password: "pass"
host: host
port: 3306
socket: /var/lib/mysql/mysql.sock 

5、config.yml
vim /home/git/gitlab-shell/config.yml
修改如下：
user: git

gitlab_url: http://localhost:8080/gitlab/
http_settings:
self_signed_cert: false
repos_path: "/home/git/repositories/"
auth_file: "/home/git/.ssh/authorized_keys"
redis:
bin: "/bin/redis-cli"
namespace: resque:gitlab
host: host
port: 6379
pass: pass
database: db
log_level: INFO
audit_usernames: false

6、gitlab
vim /etc/default/gitlab
gitlab_workhorse_options="-listenUmask 0 -listenNetwork tcp -listenAddr 127.0.0.1:8181 -authBackend http://127.0.0.1:8080/gitlab -authSocket $socket_path/gitlab.socket -documentRoot $app_root/public"

7、relative_url.rb修改相对路径
cp /home/git/gitlab/config/initializers/relative_url.rb.sample /home/git/gitlab/config/initializers/relative_url.rb
vim /home/git/gitlab/config/initializers/relative_url.rb
Rails.application.configure do
  config.relative_url_root = "/gitlab"
end

8、修改nginx.conf
vim /etc/nginx/nginx.conf
server {
        #listen       80 default_server;
        #listen       [::]:80 default_server;
        #server_name  _;
        #root         /usr/share/nginx/html;
        # Load configuration files for the default server block.
        #include /etc/nginx/default.d/*.conf;
        #location / {
        #}
        #error_page 404 /404.html;
            #location = /40x.html {
        #}
        #error_page 500 502 503 504 /50x.html;
        #    location = /50x.html {
        #}
    }


9、修改gitlab.conf
vim /etc/nginx/conf.d/gitlab.conf
修改为一下内容：
## GitLab
##
## Modified from nginx http version
## Modified from http://blog.phusion.nl/2012/04/21/tutorial-setting-up-gitlab-on-debian-6/
## Modified from https://raymii.org/s/tutorials/Strong_SSL_Security_On_nginx.html
##
## Lines starting with two hashes (##) are comments with information.
## Lines starting with one hash (#) are configuration parameters that can be uncommented.
