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
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
===================== Matched: lrzsz ==========================
lrzsz.x86_64 : The lrz and lsz modem communications programs.
安装软件包（使用yum自动安装：）
[root@webslave2 etc]# yum -y install 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

Complete!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
-------------------------------------------参考资料开始-----------------------------------
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
-------------------------------------------参考资料结束-----------------------------------
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 , 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
[root@demoserver soft]# ll

[root@demoserver jdk1.6.0_45]# java -version

Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)第三步：设置环境变量

drwxr-xr-x. 2 root root 4096 Sep 23 2011 srcvi打开文件命令：vi /etc/profile
移至文件末尾插入一个空行：输入字母o
输入以下配置信息：（注：这里的分隔符是冒号不是分号）JAVA_HOME=/usr/local/jdk
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME
export PATH
export CLASSPATH第四步：配置环境变量生效
[root@demoserver etc]# echo $JAVA_HOME
[root@demoserver etc]# source /etc/profile
[root@demoserver etc]# echo $JAVA_HOME
/usr/local/java
6.CentOS 安装tomcat
第一步、下载apache-tomcat-6.0.35.tar.gz
第二步、解压apache-tomcat-6.0.35.tar.gz
[root@demoserver soft]# tar -xvf apache-tomcat-6.0.20.tar.gz
第三步、复制路径
[root@demoserver soft]# cp -R apache-tomcat-6.0.20 /usr/local/tomcat
第四步、创建对应的软链接
[root@demoserver local]# ln -s /usr/tomcat6.0/ tomcat
[root@demoserver local]# ll
total 40
drwxr-xr-x. 2 root root 4096 Sep 23 2011 bin
drwxr-xr-x. 2 root root 4096 Sep 23 2011 etc
drwxr-xr-x. 2 root root 4096 Sep 23 2011 games
drwxr-xr-x. 2 root root 4096 Sep 23 2011 include
lrwxrwxrwx. 1 root root 21 Jan 26 22:40 jdk -> /usr/java/jdk1.6.0_45
drwxr-xr-x. 2 root root 4096 Sep 23 2011 lib
drwxr-xr-x. 3 root root 4096 Nov 26 03:02 lib64
drwxr-xr-x. 2 root root 4096 Sep 23 2011 libexec
drwxr-xr-x. 2 root root 4096 Sep 23 2011 sbin
drwxr-xr-x. 6 root root 4096 Nov 26 03:02 share
drwxr-xr-x. 2 root root 4096 Sep 23 2011 src
lrwxrwxrwx. 1 root root 15 Jan 27 01:36 tomcat -> /usr/tomcat6.0/
第五步、vi打开文件命令：vi /etc/profile
移至文件末尾插入一个空行：输入字母o
输入以下配置信息：（注：这里的分隔符是冒号不是分号）
# Tomcat environment
CATALINA_BASE=/usr/local/tomcat
CATALINA_HOME=/usr/local/tomcat
export CATALINA_BASE CATALINA_HOME第六步、CentOS安装完成Tomcat后，访问本地：http://localhost:8080/正确。但局域网http://192.168.12.128:8080/内无法访问
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)
num target prot opt source destination
1 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED
2 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0
3 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0
4 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:21
5 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22
6 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:69
7 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibitedChain FORWARD (policy ACCEPT)
num target prot opt source destination
1 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibitedChain OUTPUT (policy ACCEPT)
num target prot opt source destination
解决方案：关闭防火墙
[root@demoserver init.d]# /etc/init.d/iptables
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：
chkconfig --level 35 iptables off
[root@demoserver init.d]# /etc/init.d/iptables status
iptables: Firewall is not running.ok，通过以上问题立刻解决。
