liunx安装jenkins

linux安装jenkins【避坑】

如果首次安装，不需卸载否在：

rpm -e jenkins      #卸载
rpm -ql jenkins     #检查是否卸载成功 
find / -iname jenkins | xargs -n 1000 rm -rf    #彻底删除残留文件

下载jenkins的版本:jenkins-2.319.1-1.1.noarch.rpm

jdk版本：jdk8

安装
rpm -ivh jenkins-2.319.1-1.1.noarch.rpm
修改端口
vim /etc/sysconfig/jenkins
重新加载配置文件
systemctl daemon-reload
# 启动
systemctl start jenkins
# 重启
systemctl restart jenkins
# 停止
systemctl stop jenkins

访问ip+端口
输密码
cat /var/lib/jenkins/secrets/initialAdminPassword
如果显示显示离线
将goole改成baidu
vim /var/lib/jenkins/updates/default.json
cd /var/lib/jenkins/updates/
下面的命令要执行，要不然重启还不好使
chattr +i default.json
配置镜像
vim /var/lib/jenkins/hudson.model.UpdateCenter.xml

 One of the configured repositories failed (Jenkins-stable),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Run the command with the repository temporarily disabled
            yum --disablerepo=jenkins ...

     4. Disable the repository permanently, so yum won't use it by default. Yum
        will then just ignore the repository until you permanently enable it
        again or use --enablerepo for temporary usage:

            yum-config-manager --disable jenkins
        or
            subscription-manager repos --disable=jenkins

     5. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=jenkins.skip_if_unavailable=true

failure: repodata/repomd.xml from jenkins: [Errno 256] No more mirrors to try.
