Jenkins会OOM

Posted Nov 4, 2014

本来还打算在AWS的服务器上搭个jenkins来自动化编译的。

配置都配置好了，但是跑着跑着就会报502（nginx倒是很直白）

后来才发现，服务直接被关掉了（

sudo service jenkins status

）

估计是内存不够（主目录已经转移到了单独的硬盘上，空间肯定够的）导致了一系列问题后挂掉了吧。毕竟是AWS的最低配的EC2（VPS） T_T

网上一查，官网没找到有最低硬件配置要求，但还真有维护人员指出了这一点：

CPU : n/a (bye bye plain old school CPU at least ;) )

RAM : 1GB (I prefer 2)

HDD : depends on the needs. For my use, a 8 modules j2ee maven project + db scripts (6500 lines of code) represents less of 50 MB. I configured Jenkins to store 10 builds (500 MB)

报着也许我搞错了吧的心态（其实是死马当活马医了。。），double check了/var/log/jenkins/jenkins.log，结果：
