😌DevOps(Git+Jenkins)

`rpm包下载地址
# https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/	
`我这里选择的是12.0版本的，这是下载地址
#https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-12.0.0-ce.0.el7.x86_64.rpm

`安装依赖
[root@gitlab ~]# yum install -y curl policycoreutils openssh-server openssh-clients postfix policycoreutils-python
`安装命令   要保证centos主机有网，并且有配置yum源
[root@gitlab ~]# ls /usr/bin/wget || yum -y install wget && wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-12.0.0-ce.0.el7.x86_64.rpm --no-check-certificate

`rpm包安装命令比较简单
[root@gitlab ~]# rpm -ivh gitlab-ce-12.0.0-ce.0.el7.x86_64.rpm
`出现下面这个狐狸图像表示安装成功

`修改配置文件`
[root@gitlab ~]# sed -i "/^external_url/cexternal_url 'http://192.168.1.1'" /etc/gitlab/gitlab.rb
`重置gitlab，过程比较慢`
[root@gitlab gitlab]# gitlab-ctl reconfigure
`重置完之后会默认启动几个服务，这些都是gitlab必须的服务，包里面自带，如果重置没有成功的话，查看一下自己端口有没有被占用，尽量还是在新环境下部署gitlab`

[root@gitlab ~]# vim /etc/gitlab/gitlab.rb								# 在第 57 行后添加以下内容
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = 'smtp.qq.com'							# SMTP 服务器
gitlab_rails['smtp_port'] = 465											# SMTP 服务器端口号
gitlab_rails['smtp_user_name'] = '[email protected]'					# 邮件账号
gitlab_rails['smtp_password'] = '保密'				 						# 邮件授权码
gitlab_rails['smtp_authentication'] = 'login'
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true
gitlab_rails['gitlab_email_from'] = '[email protected]'

`重置gitlab`
[root@gitlab ~]# gitlab-ctl reconfigure

[root@gitlab ~]# gitlab-rails console
irb(main):001:0> Notify.test_email('接收人的邮箱@qq.com','Test','Hello ZhangYan').deliver_now

`生成秘钥`
[root@gitlab ~]# ssh-keygen
`查看秘钥并复制秘钥内容`
[root@gitlab ~]# cat /root/.ssh/id_rsa.pub

[root@gitlab ~]# git clone [email protected]:zhangyan/web-zhangyan
[root@gitlab ~]# ls
anaconda-ks.cfg  web-zhangyan
[root@gitlab ~]# 

`如果输入命令显示git命令找不到，直接yum -y install git就可以安装`

`因为jenkins是需要在java上运行的，所以要安装java
[root@jenkins ~]# ls
anaconda-ks.cfg  jdk-8u171-linux-x64.tar.gz
`解压缩`
[root@jenkins ~]# tar -xf jdk-8u171-linux-x64.tar.gz -C /usr/local/

[root@jenkins ~]# ls /usr/local/
bin  etc  games  include  jdk1.8.0_171  lib  lib64  libexec  sbin  share  src
`编写环境变量`
[root@jenkins ~]# cat /etc/profile.d/java.sh 
JAVA_HOME=/usr/local/jdk1.8.0_171/
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar
export PATH JAVA_HOME CLASSPATH
`生效环境变量`
[root@jenkins ~]# source /etc/profile.d/java.sh 
`查看版本，无问题`
[root@jenkins ~]# java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

`我这里下载的jenkins也是从清华源网站下载的`
[root@jenkins ~]# ls /usr/bin/wget || yum -y install wget && wget https://mirrors.tuna.tsinghua.edu.cn/jenkins/redhat/jenkins-2.331-1.1.noarch.rpm --no-check-certificate
`安装包下载好了`
[root@jenkins ~]# ls
anaconda-ks.cfg  jdk-8u171-linux-x64.tar.gz  jenkins-2.332.3-1.1.noarch.rpm

`安装依赖`
[root@jenkins ~]# yum install java-1.8.0-openjdk* -y
[root@jenkins ~]# yum -y install jenkins-2.332.3-1.1.noarch.rpm
`安装完成`
`修改配置文件`
[root@Jenkins ~]# sed -i '/^JENKINS_USER/cJENKINS_USER="root"' /etc/sysconfig/jenkins

Credentials						# 签名证书管理插件
Gitlab							# 安装后从 GitLab 获取代码
Git	和 Git Client               # 用于 Jenkins 在 GitLab 中拉取源码
GitLab Hook						# GitLab 触发 Jenkins 构建项目
Gitlab Authentication			# GitLab 和 Jenkins 认证插件
SSH Plugin						# 进程执行 Shell 脚本
Publish Over SSH				# 用于通过 SSH 部署应用

`生成秘钥`
[root@jenkins jenkins]# ssh-keygen
`查看`
[root@jenkins jenkins]# cat /root/.ssh/id_rsa.pub

`查看私钥`
[root@jenkins jenkins]# cat /root/.ssh/id_rsa

`安装httpd服务`
[root@jenkins ~]# yum -y install httpd

`写个脚本`
[root@jenkins ~]# cat web.sh 
#!/bin/bash
scp /var/lib/jenkins/workspace/web/* [email protected]:/var/www/html/

`配置免密，使scp的时候免密拷贝`
[root@jenkins ~]# ssh-copy-id 192.168.2.30

#最后运行脚本测试是否能够免密拷贝

`安装插件
Gitlab Hook Plugin
Build Authorization Token Root
Build Token Trigger

`配置身份令牌
[root@jenkins ~]# openssl rand -hex 12
44ede7a7f0d497cf6521b2ff
# -hex 输出结果为 16 进制数据，数字 12 是指定生成的随机字符为 12 字节，即 24 个 16 进制个数。
