centos7安装jenkins..

无聊,弄点事情干.
安装方式很多,找个最简单的方式安装.

修改yum源为国内的.(清华大学的.)

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

安装jdk

1.  自己下载二进制包解压安装
    http://openjdk.java.net/install/index.html openjdk主页,下载最新的或者你喜欢的.  `tar xvf openjdk-11.0.1_linux-x64_bin.tar.gz`  然后把 openjdk..in 加入到`PATH`中 `vim  /etc/profile` 等方式  
 2. `yum install java-1.8.0-openjdk -y` 安装,自己会加 PATH的 [√]

安装maven (本次不需要,war文件部署安装才需要)

wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.6.1/binaries/apache-maven-3.6.1-bin.tar.gz
tar xvf apache-maven-3.6.1-bin.tar.gz
mv apache-maven-3.6.1 /usr/local/maven3

vim /etc/profile

export MAVEN_HOME=/usr/local/maven3
export PATH="${MAVEN_HOME}/bin:$PATH"


source /etc/profile

安装jenkins

wget https://mirrors.tuna.tsinghua.edu.cn/jenkins/redhat-stable/jenkins-2.164.3-1.1.noarch.rpm
yum install jenkins-2.164.3-1.1.noarch.rpm
#systemctl enable jenkins --now             systemclt 220之后可以使用这个命令设置自启后启动服务
systemctl enable jenkins
systemctl restart jenkins
#如果jenkins服务起不来的话,systemctl status jenkins 看下原因
