centos配置数据源和java环境配置
---恢复内容开始---
一:前言
今天送走了一位同事,看着别人走勾起了我蠢蠢欲动的心啊,但是我知道,我不能那么的任性,我是men,这几天难得的清闲,所以我就弄一弄linux,昨天把网给配通了,今天配置下数据源来下载jdk,tomcat等软件,一步一步的来吧。Go!
二:数据源的配置
配置数据源的地方是在"/etc/yum.repos.d",所以我们用 cd /etc/yum.repos.d进入到这个目录下,用ls命令可以看到如下:
其中,CentOS-Base.repo就是需要配置的数据源,我们再操作linux的文件是一般是先备份的,所以可以看到我这里有个备份文件"CentOS-Base.repo.bak",
把里面的东西删除,加入如下的配置:
# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-$releasever - Base - 163.com baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #released updates [updates] name=CentOS-$releasever - Updates - 163.com baseurl=http://mirrors.163.com/centos/$releasever/updates/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras - 163.com baseurl=http://mirrors.163.com/centos/$releasever/extras/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras gpgcheck=1 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus - 163.com baseurl=http://mirrors.163.com/centos/$releasever/centosplus/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6 #contrib - packages by Centos Users [contrib] name=CentOS-$releasever - Contrib - 163.com baseurl=http://mirrors.163.com/centos/$releasever/contrib/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib gpgcheck=1 enabled=0 gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
配置完这些就可以下载jdk和tomcat了
用如下命令
wget http://download.oracle.com/otn-pub/java/jdk/7u75-b13/jdk-7u75-linux-x64.tar.gz?AuthParam=1422600482_6166cf9e13056ea25feb3b0057ba49c3-------下载jdk
在去apache的官网找到tomcat的下载路径下载 tomcat,
三:安装命令
我用的是SecureCRT来连接虚拟机的,所以我再这里面需要安装rz的命令,安装不下
(1)rz命令安装: yum
install
-y lrzsz用yum命令直接进行安装。我是在网上搜了下,看见有先下载在进行安装的,
wget http:
//www.ohse.de/uwe/releases/lrzsz.tar.gz
(2)tar zxvf jdk-7u75-linux-x64.tar.gz解压后 我的解压目录为/usr/local/soft下面,所以配置如下
配置好了执行这个命令:source /etc/profile,使得其立刻生效,此时在执行java或者java -version就可以看到
四:总结
今天终于走出了第一步,把java的环境和数据源给配置好了,感觉很不错,努力继续,同事中午走了,突然少了一个人,觉得好像很怎么怎么,天下没有不散的宴席啊,这条路上还真的是需要坚定啊。Go!
