我在尝试执行Jenkins工作时遇到错误。
git版本1.8.3.1 詹金斯2.46.2.1-滚动
我尝试将git升级到更高版本，但仍然通过跟随How to install latest version of git on CentOS 6.x/7.x链接挂起1.8.3.1。授予/ tmp权限也无法正常工作
我的RHEL7服务器来自AWS。

Jenkins git客户端插件使用临时目录中的文件将凭据传递给命令行git。如果使用noexec选项挂载了选定的临时目录，则不允许命令行git从临时目录执行脚本。 git fetch将失败，并显示堆栈跟踪信息，因为命令行git没有收到所需的凭据。
自2.4.4起（2017年4月24日发布）的Git客户端插件版本尝试在Jenkins作业环境中使用临时目录。如果Jenkins作业环境不可用，则使用系统临时目录。
解决此问题的替代方法包括：
java -Djava.io.tmpdir=/path/to/tmpdir jenkins.war -Djava.io.tmpdir=/path/to/tmpdir java -Djava.io.tmpdir=/path/to/tmpdir agent.jar -jnlpUrl http://jenkins.example.com:8080/computer/my-agent/slave-agent.jnlp -secret MY-SECRET noexec选项安装系统临时文件系统
