1、在安装jenkins的时候一直失败。报错内容是

stat: cannot stat ‘/var/cache/jenkins’: No such file or directory
stat: cannot stat ‘/var/log/jenkins’: No such file or directory
stat: cannot stat ‘/var/lib/jenkins’: No such file or directory
error: %pre(jenkins-2.150.1-1.1.noarch) scriptlet failed, exit status 1
Error in PREIN scriptlet in rpm package jenkins-2.150.1-1.1.noarch
  Verifying  : jenkins-2.150.1-1.1.noarch                                                                                                                                                                      1/1

Failed:
  jenkins.noarch 0:2.150.1-1.1

　　

因为之前已经有了

/etc/sysconfig/jenkins

删掉，重新安装即可
