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

驗證tomcat是否正常訪問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 #由此我們tomcat01web頁面可以正常運行

######################################################以上步驟，nginx，以及兩臺tomcat網站已經搭建完成########################################################

接下來我們需要讓nginx代理兩臺tomcat網站，並實現負載均衡

[[email protected] ~]# vim /usr/local/nginx/conf/nginx.conf

#############################################驗證：打開本地瀏覽器輸入nginx自己的IP地址，反復刷新，即可出現另外兩臺tomcat頁面，即實現負載####################
