linux 安装jdk

卸载自带jdk

[weblogic@localhost root]$ rpm -qa | grep jdk

java-1.7.0-openjdk-headless-1.7.0.51-2.4.5.5.el7.x86_64

java-1.7.0-openjdk-1.7.0.51-2.4.5.5.el7.x86_64

[weblogic@localhost root]$ rpm -e java-1.7.0-openjdk-1.7.0.51-2.4.5.5.el7.x86_64

错误：依赖检测失败：

    java >= 1.5 被 (已安裝) jline-1.0-8.el7.noarch 需要

    java-1.7.0-openjdk 被 (已安裝) icedtea-web-1.4.2-1.el7.x86_64 需要

强制卸载

[weblogic@localhost root]$ rpm -e --nodeps java-1.7.0-openjdk-1.7.0.51-2.4.5.5.el7.x86_64

错误：can't create 事务 lock on /var/lib/rpm/.rpm.lock (权限不够)

[weblogic@localhost root]$ su root

密码：

[root@localhost ~]# rpm -e --nodeps java-1.7.0-openjdk-1.7.0.51-2.4.5.5.el7.x86_64

[root@localhost ~]# rpm -e --nodeps java-1.7.0-openjdk-headless-1.7.0.51-2.4.5.5.el7.x86_64

提前下载好jdk 然后放在/usr/jdk目录下

[root@localhost ~]# cd /usr/jdk

[root@localhost jdk]# ll

-rw-r--r--. 1 root root 68881069 8月 17 16:58 jdk-6u45-linux-x64-rpm.bin

注意rpm.bin不能使用rpm命令安装 而是通过./的方式安装的。

[root@localhost jdk]# rpm -i jdk-6u45-linux-x64-rpm.bin

错误：jdk-6u45-linux-x64-rpm.bin: 不是 rpm 软件包 (或者没有manifest)：

[root@localhost jdk]# chmod 755 jdk-6u45-linux-x64-rpm.bin

[root@localhost jdk]# ./jdk-6u45-linux-x64-rpm.bin
