1.创建solr用户和秘密
useradd -m solr
passwd solr
2.tar -cvf solr.tar zip
3.CentOS下安装SecureCRT的sz/rz工具包
lrzsz是在Linux/Unix平台上同Windows进行ZModem文件上传下载，非常有好用命令行工具，相比FTP工具方便很多。
- sz:将选定的文件发送(send)到本地机器;
- rz：运行该命令会弹出一个文件选择窗口, 从本地选择文件上传到服务器(receive)。
新安装的CentOS5.5系统，在secureCRT下使用rz sz 上传下载文件时出现如下提示：
\[root@webslave2 etc\]\# sz hosts
\-bash: sz: command not found
\[root@webslave2 etc\]\# 由上述现象可知，很可能没有安装相应的软件包；sz rz 命令所需要的软件包是lrzsz
下面检查软件包是否安装？
\[root@webslave2 etc\]\# yum list installed lrzsz
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
\* addons: mirror.neu.edu.cn
\* base: mirror.neu.edu.cn
\* extras: mirror.neu.edu.cn
\* updates: mirror.neu.edu.cn
Error: No matching Packages to list 由此可知没有安装此包
\[root@webslave2 etc\]\# 下面安装lrzsz软件包，可通过yum安装，比较方便！
先查看下载源中的软件包
\[root@webslave2 etc\]\# yum search lrzsz
Loaded plugins: fastestmirror

4.CentOS 卸载自带OpenJdk
\[root@demoserver ~\]\# rpm -qa | grep java
java-1.6.0-openjdk-1.6.0.0-1.41.1.10.4.el6.x86\_64
tzdata-java-2011l-4.el6.noarch
\[root@demoserver ~\]\# rpm -e --nodeps java-1.6.0-openjdk-1.6.0.0-1.41.1.10.4.el6.x86\_64
\[root@demoserver ~\]\# rpm -qa | grep java
tzdata-java-2011l-4.el6.noarch 安装好的CentOS会自带OpenJdk,用命令 java -version ，会有下面的信息：
java version "1.6.0"
OpenJDK Runtime Environment (build 1.6.0-b09)
OpenJDK 64-Bit Server VM (build 1.6.0-b09, mixed mode) 最好还是先卸载掉openjdk,在安装sun公司的jdk.
先查看rpm -qa | grep java
显示如下信息：
java-1.4.2-gcj-compat-1.4.2.0-40jpp.115
java-1.6.0-openjdk-1.6.0.0-1.7.b09.el5 卸载：
rpm-e --nodeps java-1.4.2-gcj-compat-1.4.2.0-40jpp.115
rpm-e --nodeps java-1.6.0-openjdk-1.6.0.0-1.7.b09.el5 还有一些其他的命令:
- rpm-qa | grep gcj
- rpm-qa | grep jdk
如果出现找不到openjdk source的话，那么还可以这样卸载
yum-y remove java java-1.4.2-gcj-compat-1.4.2.0-40jpp.115
yum-y remove java java-1.6.0-openjdk-1.6.0.0-1.7.b09.el5 5.CentOS 安装jdk1.6.0
第一、JDK1.6安装准备
从sun公司网站www.sun.com下载linux版本的jdk,我下载的版本是JDK 6 ,
地址：http://www.oracle.com/technetwork/java/javase/downloads/jdk6u35-downloads-1836443.html
http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase6-419409.html
打开终端，用cd命令进入jdk所在目录
给JDK文件授予执行权限：
chmod +x jdk-6u35-linux-x64-rpm.bin 执行安装命令：
./jdk-6u7-linux-i586.bin 如遇错误，可先切换至root用户下,su root，再执行安装命令
安装成功会在/usr/java目录下生成jdk1.6.0_35目录，就是jdk的安装目录
打开终端，输入java -version
如若有显示java的版本信息，则表示安装成功,
第二步、具体操作安装过程

问题原因：执行/etc/init.d/iptables status命令会得到一系列信息，说明防火墙开着
\[root@demoserver init.d\]\# /etc/init.d/iptables status
Table: filter
Chain INPUT (policy ACCEPT)
numtarget prot opt source destination

Usage: iptables \{start|stop|restart|condrestart|status|panic|save\}
\[root@demoserver init.d\]\# /etc/init.d/iptables stop
iptables: Flushing firewall rules: \[ OK \]
iptables: Setting chains to policy ACCEPT: filter \[ OK \]
iptables: Unloading modules: \[ OK \] 如果永久关闭，需要执行：
