登陸gitlab
第一次登陸gitlab，須要爲root用戶修改密碼，root用戶也是gitlab的超級管理員。
http://192.168.58.11
設置密碼是gitlab html

密碼不夠長，從新設置下，設置密碼是12345678，生產中注意密碼複雜點node

管理gitlab
使用root用戶和剛纔建立的密碼登陸後，你就能夠探索gitlab的奧祕了，能夠點擊圖中紅框的按鈕進入管理區域。linux

登陸成功界面git

gitlab平常管理的話，其實不多，就是天天進行備份
每小時備份也能夠，假如更新頻繁的話github

去掉註冊的功能，不讓人註冊，正常應該不讓人隨便註冊

拉到下面web

找到下面位置，去掉勾，保存sql

千萬不要找錯地方了。是Sign-up 而不是Sign-in

再次推出登陸，就沒註冊那一項了

建立個項目以前須要先建立一個組

先建立一個組

填寫以下shell

訪問級別，設置爲內部

建立成功json

在組裏面建立項目

這裏就能夠從下拉列表選擇了
項目描述
Import project from 這裏能夠看到它還能夠從其它平臺導入
能夠從github遷移過來vim

能夠經過key鏈接它

隨便輸入一串

提交

添加成功

把代碼拉下來

經過ssh拉下來

如今上傳和克隆都不行，你須要配置驗證

把公鑰放上去

看到沒ssh-key的提示了

複製git@192.168.58.11:web/web-demo.git

遇到下面問題
[www@linux-node1 code]$ git
-bash: git: command not found
安裝git便可

因爲實驗環境變化，上面的ssh-key是5天前的，環境變化致使key失效，從新配置key

刪除以前的從新添加

拉取代碼（在這以前，先刪除code目錄下的web-demo）

(the 'simple' mode was introduced in Git 1.7.11. Use the similar mode
'current' instead of 'simple' if you sometimes use older versions of Git)

8c8b1977f52f30c55d670f53b3be735a189c6f75
[www@linux-node1 web-demo]$

這個git id很長，咱們通常取前五、六、8位。不多見前5位重複的。字符串截取

[www@linux-node1 web-demo]$ git show | grep commit |cut -d ' ' -f2
8c8b1977f52f30c55d670f53b3be735a189c6f75

[www@linux-node1 web-demo]$ echo ${API_VERL:0:6}
8c8b19
[www@linux-node1 web-demo]$

修改以前代碼，這裏直接執行git pull。不執行echo了

code_get(){
    writelog "code_get";
    cd $CODE_DIR  && git pull
    cp -r ${CODE_DIR} ${TMP_DIR}/
    API_VER="456"
}

版本也自動獲取

code_get(){
    writelog "code_get";
    cd $CODE_DIR  && git pull
    cp -r ${CODE_DIR} ${TMP_DIR}/
    API_VERL=$(git show | grep commit |cut -d ' ' -f2)
    API_VER=$(echo ${API_VERL:0:6})
}

保存，退出。從新部署下。看到以下，版本變了規整了

服務器都有這個包，沒解壓，網頁訪問沒變化。

檢查下腳本

node1解壓了。可是node2沒解壓

找到緣由了。由於啓動了git。它佔用80端口。
而咱們先部署的node1，而node1是先測試，經過才能繼續後面的解壓部署操做
node1確定測試沒經過。由於80端口給git了。
node2理所固然沒解壓了
腳本沒問題

url_test裏面加個提示。測試不經過顯示在控制檯

url_test(){
    URL=$1
    curl -s --head $URL | grep "200 OK"
    if [ $? -ne 0 ];then
      shell_unlock;
      writelog "test error" && exit;
    fi
}

改爲這個便可

url_test(){
    URL=$1
    curl -s --head $URL | grep "200 OK"
    if [ $? -ne 0 ];then
      shell_unlock;
      echo "test error" && exit;
    fi
}

再次部署，就提示error了

git在用80端口

這裏測試的話，能夠在main函數裏把node1先去掉

	echo "Deploy is running"  && exit;

找它的配置文件

這裏能夠把external_url以後域名改爲IP（早期我就修改了）

[root@linux-node1 etc]# rpm -ql gitlab-ce | less
[root@linux-node1 etc]# cd /etc/gitlab/
[root@linux-node1 gitlab]# grep external_url gitlab.rb 
##! For more details on configuring external_url see:
external_url 'http://192.168.58.11'
# registry_external_url 'https://registry.gitlab.example.com'
# pages_external_url "http://pages.example.com/"
# mattermost_external_url 'http://mattermost.example.com'
[root@linux-node1 gitlab]#

改完以後，須要從新配置

[root@linux-node1 gitlab]# gitlab-ctl reconfigure

從新登陸

若是從新登陸，發現還沒被改掉，應該是改以前的項目沒變，新建的項目用的都是IP了

疑難解答。若是 http://192.168.58.12/提示下面這種

很大可能8080端口被別的佔用了
