Jenkins 安装

强烈建议不要用docker安装jenkins,jenkins本身用docker安装不麻烦,但是安装那些插件太麻烦了

1.安装java(JDK1.8以上的java版本)

查找java相关的列表

yum -y list java*

 安装:

yum install java-1.8.0-openjdk-devel.x86_64

配置环境变量:

vi /etc/profile

在文件最后加入:

JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.312.b07-2.el8_5.x86_64   ##java安装目录,通过yum安装的默认路径为:/usr/lib/jvm
JRE_HOME=$JAVA_HOME/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME JRE_HOME CLASS_PATH PATH

让修改生效:

source /etc/profile

测试:

java -version

 看到版本号就成功了

2.安装jenkins

1.安装:

 sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
 sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
 yum install jenkins

不要怀疑就是这么简单:官网 https://pkg.jenkins.io/redhat-stable/

启动:

/etc/init.d/jenkins start

查看状态:

systemctl status jenkins

 发现端口是8080,其实这是默认端口,我们可以修改的端口

2.修改端口(也可能不改)

①端口修改不生效

vim /etc/sysconfig/jenkins

##修改
JENKINS_PORT="8089"

②端口修改不生效

vim /usr/lib/firewalld/services/jenkins.xml

修改
port="8089"

真正生效的修改方法

vim /usr/lib/systemd/system/jenkins.service

修改
Environment="JENKINS_PORT=8089"
# 重新加载配置文件
systemctl daemon-reload

再次查看状态

systemctl status jenkins

ps:如果没有改就重启一下

/etc/init.d/jenkins restart

问题1:

 有时这就是单纯在 启动时超时了,重新启动就可以了

2.nginx反向代理jenkins

1.正常安装的nginx

server {
    listen       80;
    server_name jenkins.local.test; # 域名设置

    location / {
       proxy_pass http://127.0.0.1:8089;
       proxy_redirect off;
       proxy_set_header Host $host;
       proxy_set_header X-Real-IP $remote_addr;
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       proxy_set_header X-Forwarded-Proto $scheme;
    }
}

2.docker安装的nginx

server {
    listen       80;
    server_name jenkins.local.test; # 域名设置

    location / {
       proxy_pass http://172.22.0.1:8089;    ## 172.22.0.1  是docker的默认网关
       proxy_redirect off;
       proxy_set_header Host $host;
       proxy_set_header X-Real-IP $remote_addr;
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       proxy_set_header X-Forwarded-Proto $scheme;
    }
}

 ps:查看docker默认网关

docker network ls

docker network inspect 8091c59ed73c
