Ubuntu1804/Ubun2004安装jenkins

上传jdk软件包

root@ubuntu-1:~# ls
jdk-8u191-linux-x64.tar.gz

解压jdk，并配置环境变量

解压jdk
root@ubuntu-1:~# tar xf jdk-8u191-linux-x64.tar.gz -C /usr/local/

创建软连接，方便系统调用
root@ubuntu-1:~# ln -s /usr/local/jdk1.8.0_191/ /usr/local/jdk


配置jdk环境变量
cat >  /etc/profile.d/jdk.sh <<EOF
export JAVA_HOME=/usr/local/jdk
export JRE_HOME=\$JAVA_HOME/jre
export CLASSPATH=\$JAVA_HOME/lib/:\$JRE_HOME/lib/
export PATH=\$PATH:\$JAVA_HOME/bin
EOF

让环境变量生效
root@ubuntu-1:~# source /etc/profile.d/jdk.sh

创建软连接，如果不创建，安装的时候可能会报错
root@ubuntu-1:~# ln -s /usr/local/jdk/bin/java /bin/java

查看环境变量是否生效
root@ubuntu-1:~# java -version
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)
