Linux服务器配置（一）
jdk,tomcat,nginx记录
最近公司买了三台服务器System x3650 M5用来跑公司的项目。现，记录一下真机部署与后期维护历程~
因为系统是服务器买来就装好的，所以避免不了有一些不符合应用场景的程序，服务等，首先使用yum grouplist命令来看看当前系统中已经包含哪些东西~

系统默认安装了java平台，看看是不是我们想要的。
[root@hart ~]# java -version
java version "1.7.0_45"
OpenJDK Runtime Environment (rhel-2.4.3.3.el6-x86_64 u45-b15)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)
原来安装的是OpenJDK,好吧。我们自己动手换成我们自己常用的oracle jdk.那么首先我们要将OpenJDK卸载。
[root@hart ~]# rpm -qa | grep jdk
java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64
java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64
[root@hart ~]# yum -y remove java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64 java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64
....
....
....
Complete!
[root@hart ~]#
ok 卸载完成。
http://www.oracle.com/technetwork/java/javase/downloads/index.html
自行下载jdk
[root@hart hart]# tar -zxvf jdk-7u80-linux-x64.gz //解压jdk到当前目录下
[root@hart hart]# mkdir /usr/java
[root@hart hart]# mv jdk1.7.0_80/ /usr/java/jdk1.7
[root@hart jdk1.7]# vi /etc/profile
//在文件最后面添加
export JAVA_HOME=/usr/java/jdk1.7/
export PATH=$PATH:$JAVA_HOME\bin
export CLASSPATH=.
//保存 退出 :wq
[root@hart jdk1.7]# source /etc/profile
[root@hart jdk1.7]# java
[root@hart jdk1.7]# javac
[root@hart jdk1.7]# java -version
java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)
Ok~JDK安装配置完成。下面安装tomcat
[root@hart tomcat]# ls
apache-tomcat-7.0.69.tar.gz
[root@hart tomcat]# tar -zxvf apache-tomcat-7.0.69.tar.gz
[root@hart tomcat]# ls
apache-tomcat-7.0.69 apache-tomcat-7.0.69.tar.gz
[root@hart tomcat]# mv apache-tomcat-7.0.69 tomcat7.0
[root@hart tomcat]# ls
apache-tomcat-7.0.69.tar.gz tomcat7.0
配置tomcat
[root@hart tomcat]# cd tomcat7.0/conf/
[root@hart conf]# ls
catalina.policy context.xml server.xml web.xml
catalina.properties logging.properties tomcat-users.xml
[root@hart conf]# vi server.xml
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" URIEncoding="UTF-8" />
//port自行修改，最后加上URIEncoding="UTF-8"可以避免地址栏路径中文乱码问题
//在<Host>标签中添加以下代码，可以使tomcat访问虚拟路径
<Context docBase="/usr/filePath" path="/file" />
//此外,在context.xml中配置也可以
[root@hart conf]# vi web.xml
<servlet>
<servlet-name>default</servlet-name>
<servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>0</param-value>
</init-param>
<init-param>
<param-name>listings</param-name>
<!-- 将false改为true-->
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
Ok,安装nginx
[root@hart nginx]# ls
nginx-1.8.1.tar.gz
[root@hart nginx]# tar -zxvf nginx-1.8.1.tar.gz
[root@hart nginx]# cd nginx-1.8.1
[root@hart nginx-1.8.1]# ./configure
[root@hart nginx-1.8.1]# ./configure

./configure: error: C compiler cc is not found
//没有gcc,安装
[root@hart nginx-1.8.1]# yum -y install gcc
Complete!
[root@hart nginx-1.8.1]# ./configure
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.
//安装pcre-devel
[root@hart nginx-1.8.1]# yum install pcre-devel

[root@hart nginx-1.8.1]# ./configure
./configure: error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module
option, or install the zlib library into the system, or build the zlib library

[root@hart nginx-1.8.1]# yum -install zlib-devel

nginx代理tomcat
//在/usr/local/nginx/conf/nginx.conf中:
//配置tomcat节点:在http节点内部,server节点外部

}
//server节点内部:
location / {

proxy_redirect off;

}
只是现在从别的机器还访问不了，怎么办呢？
[root@hart sbin]# vi /etc/rc.d/init.d/iptables
//加入以下这条规则
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
[root@hart sbin]# service iptables restart
ok.这样就可以访问啦~~
先这样简单的记录一下步骤。深入的运维管理，让我们一起慢慢学习。
