集群session配置成功，使用浏览器访问反代服务器的80端口检验效果

至此，httpd反代tomcat集群，并且tomcat集群session复制都成功实现了

Nginx反代tomat集群配置

在这里我们为了节约资源就把nginx反代服务器配置到TomcatB服务器上

[root@TomcatB ~]# yum install -y nginx

[root@TomcatB ~]# cp/etc/nginx/nginx.conf{,.bak}

[root@TomcatB ~]# vim /etc/nginx/nginx.conf

Nginx默认配置文件需要修改以下几处

定义后端tomcat集群

upstreamtomcatservers {

server 192.168.0.20:8080;

server 192.168.0.21:8080;

}

注释IPV6监听

server {

listen 80 default_server;

#listen [::]:80default_server;

定义完全反代至后端tomcat集群

location / {

root /usr/share/tomcat/wepapps/ROOT;

index index.jsp;

proxy_pass http://tomcatservers;

}

定义让后端tomcat集群获取客户端真实IP

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

[root@TomcatB ~]# nginx -t

nginx: the configuration file/etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conftest is successful

[root@TomcatB ~]#

继httpd反代tomcat集群配置之后需要修改的地方

[root@TomcatA ~]# vim/etc/tomcat/server.xml

<ValveclassName="org.apache.catalina.valves.AccessLogValve"directory="logs"

prefix="localhost_access_log." suffix=".txt"

pattern="%{X-Forwarded-For}i %l %u %t "%r" %s %b"%{Referer}i"

"%{User-Agent}i""/>

<!--pattern="%h %l %u %t"%r" %s %b "%{Referer}i"

"%{User-Agent}i""/> -->

[root@TomcatA ~]# systemctl restart tomcat

[root@TomcatB ~]# vim/etc/tomcat/server.xml
