下载好Jenkins 2.235.5 LTS .war上传到我们的linux服务器，接下来就可以启动jenkins了
启动jenkins，默认端口是8080
java -jar Jenkins 2.235.5 LTS .war
jenkins在启动成功后会默认随机生成一个管理员密码保存在 /root/.jenkins/secrets/initialAdminPassword这个文件中，用户可以修改。
docker安装jenkins
docker run -u root -p 8080:8080 -p 50000:50000 -v /usr/local/work/jenkins:/var/jenkins_home --name j01 -idt jenkins
通过docker logs -f可以查看生成的管理员密码
访问jenkins控制台
输入管理员密码后进入到下面的页面。我们可以选择安装推荐的插件
centos7安装jenkins
下载jenkins安装包到当前目录下
wget http://pkg.jenkins-ci.org/redhat-stable/jenkins-2.190.3-1.1.noarch.rpm
直接安装jenkins
rpm -ivh jenkins-2.190.3-1.1.noarch.rpm
修改jenkins配置
vim /etc/sysconfig/jenkins
JENKINS_USER="root"
JENKINS_PORT="8888"
启动Jenkins
systemctl start jenkins
查看Jenkins启动状态
[root@localhost ~]# systemctl status jenkins

目前使用的jdk7，但是jenkins最低需要jdk8，先升级jdk
安装jdk8
tar -zxvf jdk-8u441-linux-x64.tar.gz mv jdk1.8.0_441 /usr/local/jdk8
vim /etc/profile
source /etc/profile /usr/local/jdk8/bin/java -version
vim /etc/init.d/jenkins
systemctl daemon-reload
systemctl restart jenkins
systemctl status jenkins
