Centos6.7 运行 eclipse出错解决办法

今天在centos下运行eclipse c++出现来点问题。主要原因是jdk点安装以及环境变量始终不对。

尝试在/etc/profile中手动配置，也没有成功。

做了如下步骤成功解决。

1.查看jdk安装版本，命令是: rpm -qa | grep jdk，运行结果如下

java-1.8.0-openjdk-1.8.0.144-0.b01.el6_9.x86_64
jdk-9-9-ga.x86_64
java-1.6.0-openjdk-1.6.0.35-1.13.7.1.el6_6.x86_64
java-1.7.0-openjdk-1.7.0.79-2.5.5.4.el6.x86_64
java-1.8.0-openjdk-devel-1.8.0.144-0.b01.el6_9.x86_64
java-1.8.0-openjdk-headless-1.8.0.144-0.b01.el6_9.x86_64

2.删除版本9和1.6，命令是
yum -y remove jdk-9-9-ga.x86_64
yum -y remove java-1.6.0-openjdk-1.6.0.35-1.13.7.1.el6_6.x86_64
问题得到解决。

安装1.8点步骤在删除版本之前就做了，命令如下，这步比较关键。免去手动设置环境变量点麻烦.
