来源: navyaijm2012 分享至:
一、所需软件 jdk-6u22-linux-x64.bin、apache-tomcat-6.0.26.tar.gz   二、安装 1、安装JDK ./jdk-6u22-linux-i586.bin mv jdk1.6.0_22/ /usr/local/   2、安装tomcat tar zxvf apache-tomcat-6.0.26.tar.gz mv apache-tomcat-6.0.26 /usr/local/ cd /usr/local/ mv apache-tomcat-6.0.26/ tomcat1   3、配置环境变量 vi /etc/profile JAVA_HOME=/usr/local/jdk1.6.0_22 CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar PATH=$JAVA_HOME/bin:$PATH export JAVA_HOME CLASSPATH PATH   source /etc/profile   4、测试 java -version java version "1.6.0_22" Java(TM) SE Runtime Environment (build 1.6.0_22-b04) Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)   5、用普通用户启动tomcat cd /usr/local/tomcat1/bin tar zxvf jsvc.tar.gz cd jsvc-src chmod +x configure ./configure --with-java=/usr/local/jdk1.6.0_22 make   6、创建用户 useradd tomcat   7、修改配置文件 vi server.xml(修改如下内容) <Engine name="Catalina" defaultHost="localhost" jvmRoute="a"> <Host name="your domain" appBase="webapps" unpackWARs="true" xmlValidation="false" xmlNamespaceAware="false">             <Context path="" docBase="/webroot/" workDir="" /> </Host>   8、创建启动脚本 vi /etc/init.d/tomcat1 #!/bin/sh # Startup Script for Tomcat6 # description: Tomcat Daemon # processname: jsvc # pidfile: /var/run/jsvc.pid   . /etc/rc.d/init.d/functions  export JAVA_HOME=/usr/local/jdk1.6.0_22 export CATALINA_HOME=//usr/local/tomcat1   DAEMON_HOME=$CATALINA_HOME/bin   TOMCAT_USER=tomcat   # for multi instances adapt those lines. TMP_DIR=/var/tmp PID_FILE=/var/run/jsvc.pid CATALINA_BASE=$CATALINA_HOME   CATALINA_OPTS= CLASSPATH=\ $JAVA_HOME/lib/tools.jar:\ $CATALINA_HOME/bin/commons-daemon.jar:\ $CATALINA_HOME/bin/bootstrap.jar   case "$1" in  start)     #     # Start Tomcat     #     $DAEMON_HOME/jsvc-src/jsvc \     -user $TOMCAT_USER \     -home $JAVA_HOME \     -Dcatalina.home=$CATALINA_HOME \     -Dcatalina.base=$CATALINA_BASE \     -Djava.io.tmpdir=$TMP_DIR \     -wait 10 \     -pidfile $PID_FILE \     -outfile $CATALINA_HOME/logs/catalina.out \    -errfile '&1' \     $CATALINA_OPTS \     -cp $CLASSPATH \     org.apache.catalina.startup.Bootstrap     #     # To get a verbose JVM     #-verbose \     # To get a debug of jsvc.     #-debug \     exit $?     ;;    stop)     #     # Stop Tomcat     #     $DAEMON_HOME/jsvc-src/jsvc \     -stop \     -pidfile $PID_FILE \     org.apache.catalina.startup.Bootstrap     exit $?     ;;    *)     echo "Usage tomcat.sh start/stop"     exit 1;; esac   chmod a+x /etc/init.d/tomcat1   9、启动|关闭 su - tomcat /etc/init.d/tomcat1 start|stop   三、安装第二个tomcat cp –r /usr/local/tomcat1 /usr/local/tomcat2 cp /etc/init.d/tomcat1 /etc/init.d/tomcat2   vi server.xml(修改如下内容) <Server port="8105" shutdown="SHUTDOWN"> <Connector port="8180" protocol="HTTP/1.1"                connectionTimeout="20000"                redirectPort="9443"                URIEncoding="UTF-8" /> <Connector port="8109" protocol="AJP/1.3" redirectPort="9443" /> <Engine name="Catalina" defaultHost="localhost" jvmRoute="b">   vi /etc/init.d/tomcat2(修改如下内容) export CATALINA_HOME=//usr/local/tomcat2   启动|关闭 su - tomcat /etc/init.d/tomcat2 start|stop   四、配置调度器nginx vi nginx.conf(增加以下内容)    upstream tomcatserver {       server 127.0.0.1:8080 srun_id=a weight=5 max_fails=2 fail_timeout=600s;       server 127.0.0.1:8180 srun_id=b weight=5 max_fails=2 fail_timeout=600s;       jvm_route $cookie_JSESSIONID|sessionid reverse;    }   server {    listen 80;    server_name your domain;      location / {       root /webroot;       index index.jsp index.do index.html index.htm;       rewrite "^/([0-9]+)\.html$" /a.jsp?id=$1 last;    }      location ~ ^/WEB-INF/* {       deny all;    }      location ~ .*\.(jsp|do)?$ {       proxy_pass http://tomcatserver;       include proxy.conf;    }      log_format mainlogs '$remote_addr - $remote_user [$time_local] "$request" '                      '$status $body_bytes_sent "$http_referer" '                      '"$http_user_agent" "$http_x_forwarded_for"';      access_log /var/log/nginx/oa.log mainlogs;      location ~ /\..+ {       deny all;    } }   重启nginx /usr/local/nginx/sbin/nginx -t /etc/init.d/nginx reloadhttp://www.linuxso.com/fuzai/22990.html
