一、安裝gitlab
1、需要安裝包如下：（版本自行網上下載）
openssh-server-6.6.1p1-11.el7.x86_64.rpm
gitlab-ce-10.1.4-ce.0.el7.x86_64.rpm
policycoreutils-python-2.2.5-15.el7.x86_64.rpm
將三個安裝包放到root根目錄下
[root@localhost ~]# ls
anaconda-ks.cfg openssh-server-6.6.1p1-11.el7.x86_64.rpm
gitlab-ce-10.1.4-ce.0.el7.x86_64.rpm policycoreutils-python-2.2.5-15.el7.x86_64.rpm
2、按順序安裝下面的依賴，在安裝的過程中，也會自動升級很多其他依賴的，所以是在聯網情況下安裝的。
[root@localhost ~]# yum install -y curl
[root@localhost ~]# yum install -y policycoreutils-python
[root@localhost ~]# yum install -y openssh-server
[root@localhost ~]# yum install gitlab-ce-10.1.4-ce.0.el7.x86_64.rpm
3、安裝成功會出現gitlab圖標
#################上面還有很多安裝信息，下面是部分截取，出現圖標即爲安裝成功
正在安裝 : gitlab-ce-10.1.4-ce.0.el7.x86_64 1/1
It looks like GitLab has not been configured yet; skipping the upgrade script.

Thank you for installing GitLab!
GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:
sudo gitlab-ctl reconfigure
For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md
驗證中 : gitlab-ce-10.1.4-ce.0.el7.x86_64 1/1
已安裝:
gitlab-ce.x86_64 0:10.1.4-ce.0.el7
完畢！
4、配置gitlab，編輯 vi /etc/gitlab/gitlab.rb文件，將external_url 'http://gitlab.example.com'改爲：external_url 'http://192.168.190.147:11000'（ip地址+端口號）保存退出。
5、重新配置並重啓gitlab，測試環境下可以將防火牆關閉，或者開放指定端口（開放的端口號和剛剛填寫的端口號需要一致）
[root@localhost ~]# gitlab-ctl reconfigure ##重新配置gitlab
[root@localhost ~]# service firewalld stop ##關閉防火牆
[root@localhost ~]# gitlab-ctl status ##查看gitlab的運行狀態

10、打開瀏覽器，訪問剛剛配置的地址http://192.168.190.147:11000登錄gitlab，第一次登錄會讓你設置密碼的，密碼最少爲8爲，設置完成後即可登錄，用戶名爲root。
二、安裝git
1、首先需要安裝git的依賴包，並刪除已有git
[root@localhost ~]# yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker
[root@localhost ~]# yum remove git
2、切換到git的包文件存放目錄下，這裏我是放在了root目錄下，進入目錄：然後解壓安裝包
[root@localhost ~]# tar -zxvf git-2.8.3.tar.gz
3、安裝包解壓完成後，進入解壓後的Git文件下，配置安裝路徑，然後編譯並且安裝
[root@localhost ~]# cd git-2.8.3
[root@localhost ~]# ./configure prefix=/usr/local/git/ ##配置安裝路徑
[root@localhost ~]# make && make install ##編譯並且安裝
4、將git的指令添加到bash中，運行vi /etc/profile進入編輯，在最後一行添加：
export PATH=$PATH:/usr/local/git/bin
最後運行source /etc/profile命令讓上述配置文件立即生效
最後運行git --version命令查看git的版本號
