步骤如下：

1，停止jinkens

1	service jenkins stop

2, 修改jenkins配置文件

vim /etc/sysconfig/jenkins，修改JENKINS_HOME

## Description: Jenkins Automation Server
## Type: string
## Default: "/var/lib/jenkins"
## ServiceRestart: jenkins
#
# Directory where Jenkins store its configuration and working
# files (checkouts, build reports, artifacts, ...).
#
#JENKINS_HOME="/var/lib/jenkins"
JENKINS_HOME="/mydata/jenkins/jenkins"
 
## Type: string
## Default: ""
## ServiceRestart: jenkins
#
# Java executable to run Jenkins
# When left empty, we'll try to find the suitable Java.
#
JENKINS_JAVA_CMD=""
 
## Type: string
## Default: "jenkins"
## ServiceRestart: jenkins
#
# Unix user account that runs the Jenkins daemon
# Be careful when you change this, as you need to update
# permissions of $JENKINS_HOME and /var/log/jenkins.
#
JENKINS_USER="jenkins"

3，拷贝/var/lib/jenkins到新目录

1	cp -af /var/lib/jenkins/* /mydata/jenkins/dataspace

保持jenkins的用户权限

4，重启jenkins
