Solr 安装配置一：Centos6 安装和配置jdk1.7

1、在/usr下创建java目录

[root@localhost ~]# cd /usr/
[root@localhost usr]# ls
bin  etc  games  include  lib  libexec  local  sbin  share  src  tmp
[root@localhost usr]# mkdir java 
[root@localhost usr]# ls
bin  etc  games  include  java  lib  libexec  local  sbin  share  src  tmp
[root@localhost usr]# ^C
[root@localhost usr]# 

2、解压 jdk-7u80-linux-i586.tar.gz

[root@localhost soft]# tar -zxvf jdk-7u80-linux-i586.tar.gz 

[root@localhost soft]# ls
jdk1.7.0_80  jdk-7u80-linux-i586.tar.gz

3、配置环境变量

[root@localhost jdk1.7.0_80]# 
[root@localhost jdk1.7.0_80]# vim /etc/profile

4、环境变量生效

[root@localhost jdk1.7.0_80]#  source /etc/profile
[root@localhost jdk1.7.0_80]# 

5、测试java是否安装成功

[root@localhost jdk1.7.0_80]# java -version
java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) Server VM (build 24.80-b11, mixed mode)
[root@localhost jdk1.7.0_80]#
