CentOS系统安装配置nginx+tomcat服务器环境

一、安装tomcat：
（1）、安装jdk：
[root@localhost java]# mkdir -p /usr/java
[root@localhost java]# tar zxvf jdk-7u3-linux-x64.tar.gz -C /usr/java/
[root@localhost java]# vi /etc/profile
JAVA_HOME="/usr/java/jdk1.7.0_03"
JRE_HOME="/usr/java/jdk1.7.0_03/jre"#没有这个配置后面的tomcat关闭时会报错。
CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export JAVA_HOME
export JRE_HOME
export CLASSPATH
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC
[root@localhost java]# source /etc/profile
[root@localhost java]# java -version
java version "1.7.0_03"
Java(TM) SE Runtime Environment (build 1.7.0_03-b04)
Java HotSpot(TM) 64-Bit Server VM (build 22.1-b02, mixed mode)
二、安装tomcat：
Tomcat 下载：
# tar zxvf apache-tomcat-7.0.26.tar.gz -C /usr/src/
# cd /usr/src/
# cp -rf apache-tomcat-7.0.26 /usr/local/tomcat
# cp -rf apache-tomcat-7.0.26 /usr/local/tomcat1
将第一个TOMCAT安装在/usr/local/tomcat
# cd /usr/local/tomcat
# vi /etc/profile
在CLASSPATH后面添加$TOMCAT_HOME/common/lib/servlet.jar
在PATH后面添加：$CATALINA_HOME/lib
export TOMCAT_HOME=/usr/local/tomcat
export CATALINA_HOME=/usr/local/tomcat
export CATALINA_BASE=/usr/local/tomcat
export PATH=$PATH:$CATALINA_HOME/lib
export CLASSPATH=$CLASSPATH:$CATALINA_HOME/common/lib/servlet.jar

将第二个TOMCAT安装在/usr/local/tomcat1
设置环境变量
#vi /etc/profile
在CLASSPATH后面添加$TOMCAT_2_HOME/common/lib/servlet.jar
在PATH后面添加：$CATALINA_2_HOME/lib
export TOMCAT_1_HOME=/usr/local/tomcat1
export CATALINA_1_HOME=/usr/local/tomcat1
export CATALINA_1_BASE=/usr/local/tomcat1
export PATH=$PATH:$CATALINA_1_HOME/lib
export CLASSPATH=$CLASSPATH:$CATALINA_1_HOME/common/lib/servlet.jar

保存退出
:wq
使环境变量生效
#source /etc/profile
修改TOMCAT配置文件vi /usr/local/tomcat1/conf/server.xml（如果两个tomcat不在同一台机器可以不用修改端口）
将以下内容
    ...
       
        .../>
修改为
    ...
       
        .../>
修改TOMCAT配置启动文件/usr/local/tomcat1/bin/startup.sh
在exec上添加以下内容
export JAVA_HOME=/usr/java/jdk1.7.0_03
export JRE_HOME=/usr/java/jdk1.7.0_03/jre

export CLASSPATH=$JAVA_HOME/lib
export PATH=$JAVA_HOME/bin:$PATH  
 %注意，网上好多写成export PATH=$JAVA_HOME/bin的，在启动时会报错误%
export CATALINA_HOME=$CATALINA_2_HOME
export CATALINA_BASE=$CATALINA_2_BASE
修改TOMCAT配置启动文件/usr/local/tomcat2/bin/shutdown.sh
在exec上添加以下内容
export JAVA_HOME=/usr/local/java/jdk1.7.0_03
export JRE_HOME=/usr/java/jdk1.7.0_03/jre

export CLASSPATH=$JAVA_HOME/lib
export PATH=$JAVA_HOME/bin:$PATH
export CATALINA_HOME=$CATALINA_2_HOME
export CATALINA_BASE=$CATALINA_2_BASE
启动TOMCAT
/usr/local/tomcat1/bin/startup.sh
关闭TOMCAT
/usr/local/tomcat1/bin/shutdown.sh
三、安装nginx:
（1）、安装pcre:
# tar zxvf pcre-8.30.tar.gz -C /usr/src/
# cd /usr/src/pcre-8.30/
# ./configure
# make && make install
（2）、安装插件upstream、
# tar zxvf nginx-1.0.13.tar.gz -C /usr/src/
# tar zxvf nginx-upstream-jvm-route-0.1.tar.gz -C /usr/src/
 注意这里是解压到同一个文件夹，这里的默认名字是nginx-1.0.13
# cd /usr/nginx-1.0.13/
# patch -p0 < /usr/nginx-1.0.13/nginx_upstream_jvm_route/jvm_route.patch
（3）、安装nginx:
# ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-pcre=/usr/src/pcre-8.30 --add-module=/usr/src/nginx_upstream_jvm_route --with-openssl=/usr/ （ --user= --group=）
# make && make install
（4）、编辑nginx.conf：
# vi /usr/local/nginx/conf/nginx.conf
user nobody;
worker_processes 8;
error_log logs/nginx_error.log crit;
pid        /usr/local/nginx/nginx.pid;
