CentOS下编译安装OpenJDK6过程

分类:CentOS教程 阅读:66433 次

由于初次手动编译OpenJDK6, 踩的坑还不少, 各种依赖不足以及奇葩的事情, 特此整理记录, 给后人防坑.
编译环境信息:

[root@dev-52 ~]# uname -a Linux dev-52 2.6.32-220.el6.x86_64 #1 SMP Tue Dec 6 19:48:22 GMT 2011 x86_64 x86_64 x86_64 GNU/Linux [root@dev-52 openjdk6]# arch && cat /etc/centos-release x86_64 CentOS release 6.2 (Final) [root@dev-52 openjdk6]# nproc 8 [root@dev-52 ~]# free -m total used free shared buffers cached Mem: 7872 7695 176 0 158 6794 -/+ buffers/cache: 742 7129 Swap: 5823 0 5823

到此整个编译过程就结束了, 当然第一次编译肯定不会这么顺利的完成, 操作时需要细心, 当然编译OpenJDK7也是大同小异, 在debain平台下依赖包的名字可能会有差异, 这需要注意一下. OK, 对JVM感兴趣的同学赶紧亲自动手试一下吧.
