nginx+tomcat负载均衡

实验环境：

nginx-server：192.168.20.194

tomcatweb01:192.168.20.150

tomcatweb02:192.168.20.163

############################nginxweb平台部署完成###############################################

tomcat-web平台

[[email protected] ~]# tar zxvf jdk-7u65-linux-x64.gz -C /usr/src/

[[email protected] ~]# cd /usr/src/
[[email protected] src]# mv jdk1.7.0_65/ /usr/local/java
[[email protected] src]# which java
/usr/bin/java

[[email protected] src]# ln -s /usr/local/java/bin/* /usr/bin/

[[email protected] src]# vim /etc/profile.d/java.sh

[[email protected] src]# source /etc/profile.d/java.sh

[[email protected] src]# vim /etc/profile.d/java.sh

Java(TM) SE Runtime Environment (build 1.7.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)

java环境部署完成，接下来安装配置tomcat

[[email protected] ~]# tar zxvf apache-tomcat-7.0.54.tar.gz -C /usr/src

[[email protected] ~]# cd /usr/src/
[[email protected] src]# mv apache-tomcat-7.0.54/ /usr/local/tomcat
[[email protected] src]# /usr/local/tomcat/bin/startup.sh

[[email protected] src]# netstat -anput | grep 8080
tcp 0 0 :::8080 :::* LISTEN 27993/java

验证tomcat是否正常访问firefox http://192.168.20.150:8080

[[email protected] ~]# mkdir /web/xiaoyu -p
[[email protected] ~]# vim /web/xiaoyu/index.jsp

[[email protected] ~]# vim /usr/local/tomcat/conf/server.xml

[[email protected] ~]# elinks 192.168.20.150:8080 #由此我们tomcat01web页面可以正常运行

########################tomcatweb01服务部署完成############################################

tomcatweb02服务（第二台tomcat服务步骤是完全一样的，为了便于区别，仅仅是更改了网页内容）

准备java环境---

[[email protected] ~]# tar zxvf jdk-7u65-linux-x64.gz -C /usr/src/

[[email protected] ~]# cd /usr/src/

[[email protected] src]# mv jdk1.7.0_65/ /usr/local/java

[[email protected] src]# vim /etc/profile.d/java.sh

export JAVA_HOME=/usr/local/java
export PATH=$PATH:$JAVA_HOME/bin
