CentOS system installation and configuration nginx+tomcat server environment

1. Install tomcat:
(1), install 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”# Without this configuration, tomcat will report an error when it is closed.
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)
2. Install tomcat:
Tomcat download:
# 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
Install the first TOMCAT in /usr/local/tomcat
# cd /usr/local/tomcat
# vi /etc/profile
Add $TOMCAT_HOME/common/lib/servlet.jar after CLASSPATH
Add after PATH: $CATALINA_HOME/lib
export TOMCAT_HOME=/usr/local/tomcat
export CATALINA_HOME=/usr/local/tomcat
export CATALINA_BASE=/usr/local/tomcat
export PATH=$PATH:$CATALINA_HOME/lib
export
CLASSPATH=$CLASSPATH:$CATALINA_HOME/common/lib/servlet.jar

Install the second TOMCAT in /usr/local/tomcat1
Setting environment variables
#vi /etc/profile
Add $TOMCAT_2_HOME/common/lib/servlet.jar after CLASSPATH
Add after PATH: $CATALINA_2_HOME/lib
export TOMCAT_1_HOME=/usr/local/tomcat1
export CATALINA_1_HOME=/usr/local/tomcat1
export CATALINA_1_BASE=/usr/local/tomcat1
export PATH=$PATH:$CATALINA_1_HOME/lib
export
CLASSPATH=$CLASSPATH:$CATALINA_1_HOME/common/lib/servlet.jar

Save and exit
:wq
Enabling environment variables to take effect
#source /etc/profile
Modify the TOMCAT configuration file vi
/usr/local/tomcat1/conf/server.xml (if the two tomcats are not on the same machine, you don’t need to modify the port)
Put the following
…
<Connector port="8080" protocol="HTTP/1.1"
…

<Host name="localhost"
appBase="webapps"
…/>
Change to
…
<Connector port="9080" protocol="HTTP/1.1"
…

<Host name="localhost"
appBase="/usr/local/www/web" (You don't need to change it here, you can jump directly to the tomcat home page during the test)
…/>
Modify the TOMCAT configuration startup file /usr/local/tomcat1/bin/startup.sh
Add the following on exec
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:$PATH
%Attention, many of the online ones are written as export PATH=$JAVA_HOME/bin, and an error will be reported at startup%
export CATALINA_HOME=$CATALINA_2_HOME
export CATALINA_BASE=$CATALINA_2_BASE
Modify the TOMCAT configuration startup file /usr/local/tomcat2/bin/shutdown.sh
Add the following on exec
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
Start TOMCAT
/usr/local/tomcat1/bin/startup.sh
Close TOMCAT
/usr/local/tomcat1/bin/shutdown.sh
3. Install nginx:
(1), install pcre:
# tar zxvf pcre-8.30.tar.gz -C /usr/src/
# cd /usr/src/pcre-8.30/
# ./configure
# make && make install
(2), install the plug-in 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/
Note that this is decompressed to the same folder, the default name here is 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), install 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), edit nginx.conf:
# vi /usr/local/nginx/conf/nginx.conf
