Jenkins

1) 安装OpenJDK11
[root@jenkins ~]# yum  install java-11-openjdk java-11-openjdk-devel -y

2) 配置OpenJDK11 Shell环境
[root@jenkins ~]# cat > /etc/profile.d/java11.sh <<EOF
export JAVA_HOME=$(dirname $(dirname $(readlink $(readlink $(which javac)))))
export PATH=\$PATH:\$JAVA_HOME/bin
EOF

[root@jenkins ~]# source /etc/profile.d/java11.sh

3) 确认java可正常使用
[root@jenkins ~]# java --version
openjdk 11.0.6 2020-01-14 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.6+10-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.6+10-LTS, mixed mode, sharing)

4) 如果有多个Java版本，可按以下操作切换
[root@jenkins ~]# alternatives --config java
There is 1 program that provides 'java'.

  Selection    Command
-----------------------------------------------
*+ 1           java-11-openjdk.x86_64 (/usr/lib/jvm/java-11-openjdk-11.0.6.10-1.el7_7.x86_64/bin/java)

Enter to keep the current selection[+], or type selection number: 1

1) 安装Jenkins Repo
[root@jenkins ~]# cd /etc/yum.repos.d
[root@jenkins yum.repos.d]# curl -O https://pkg.jenkins.io/redhat-stable/jenkins.repo

2) 下载Jenkins GPG Key
[root@jenkins yum.repos.d]# rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
[root@jenkins yum.repos.d]# cd
[root@jenkins ~]# 

3) 安装并启动Jenkins
[root@jenkins ~]# yum install jenkins -y

[root@jenkins ~]# systemctl start jenkins
[root@jenkins ~]# systemctl enable jenkins
jenkins.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig jenkins on

4) 加速Jenkins插件下载(需等到Jenkins服务真正启动)
# 耐心等待一会,JAVA比较慢.....大约5~15s左右

4.1) 修改Jenkins插件为国内源
[root@jenkins ~]# vim /var/lib/jenkins/hudson.model.UpdateCenter.xml
将https:......改为如下内容
https://mirror.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json

4.2) 在清华tuna镜像下载Jenkins插件
[root@jenkins ~]# yum --enablerepo=epel install nginx -y
[root@jenkins ~]# vim /etc/nginx/conf.d/mirrors.jenkins-ci.org.conf
server
    {
        listen 80;
        server_name mirrors.jenkins-ci.org;

        location / {
            proxy_redirect off;
            proxy_pass https://mirrors.tuna.tsinghua.edu.cn/jenkins/;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Accept-Encoding "";
            proxy_set_header Accept-Language "zh-CN";
        }
        index index.html index.htm index.php;

        location ~ /\.
        {
            deny all;
        }

        access_log  /var/log/nginx/jenkins.access.log;
        error_log   /var/log/nginx/jenkins.error.log;
    }

[root@jenkins ~]# vim /etc/hosts
将jenkins-ci的site重定向为本地
......
......

[root@jenkins ~]# systemctl enable --now nginx
 
[root@jenkins ~]# systemctl restart jenkins

5) 防火墙配置
[root@jenkins ~]# firewall-cmd --add-port=8080/tcp --permanent
