[root@tomcat1 ~]# vi /usr/local/tomcat/conf/server.xml
150         <Context docBase="/web/webapp" path="" reloadable="false"></Context>    #在150行左右位置添加
[root@tomcat1 ~]# mkdir -p /web/webapp
[root@tomcat1 ~]# cat <<END >>/web/webapp/index.jsp
192.168.100.102
END
[root@tomcat1 ~]# /usr/local/tomcat/bin/shutdown.sh
[root@tomcat1 ~]#  /usr/local/tomcat/bin/startup.sh

• 配置Nginx服务的反向代理

[root@nginx ~]# vi /usr/local/nginx/conf/nginx.conf
     34     upstream tomserver {
     35         server 192.168.100.102:8080 weight=1;
     36         server 192.168.100.103:8080 weight=2;
     37     }
     52     location ~\.(jsp|do|js|css|png|jpg|jpeg)$ {
     53         proxy_pass      http://tomserver;
     54     }
[root@nginx ~]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

• 访问测试Nginx验证页面切换
  
  
  

• 安装部署MySQL程序

[root@mysql ~]# yum -y install mariadb-server mysql
[root@mysql ~]# systemctl start mariadb
[root@mysql ~]# systemctl enable mariadb
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.
[root@mysql ~]# netstat -utpln |grep 3306
tcp        0      0 0.0.0.0:3306            0.0.0.0:*               LISTEN      1423/mysqld 
[root@mysql ~]# mysqladmin -u root password 123123
[root@mysql ~]# mysql -uroot -p123123

• 将测试项目的文件部署到Tocmat节点(两个tomcat节点配置一致，在此列举tomcat1)

[root@tomcat1 webapp]# ls 
WebRoot
[root@tomcat1 webapp]# vi /web/webapp/WebRoot/WEB-INF/classes/database.properties
driver=com.mysql.jdbc.Driver
#在和mysql传递数据的过程中，使用unicode编码格式，并且字符集设置为utf-8
url=jdbc:mysql://192.168.100.104:3306/smbms?useUnicode=true&characterEncoding=utf-8
user=linux
password=123123
[root@tomcat1 webapp]#  vi /usr/local/tomcat/conf/server.xml
150         <Context docBase="/web/webapp/WebRoot/" path="" reloadable="false"></Context>
root@tomcat1 webapp]# /usr/local/tomcat/bin/shutdown.sh
[root@tomcat1 webapp]# /usr/local/tomcat/bin/startup.sh

• 测试访问tomcat单点，登录超时管理系统
  
  

• 修改Nginx配置，实现会话保持,避免登录错误

[root@nginx ~]# vi /usr/local/nginx/conf/nginx.conf
     34     upstream tomserver {
     35         ip_hash;
     36         server 192.168.100.102:8080 weight=1;
     37         server 192.168.100.103:8080 weight=2;
     38     }

• 修改Nginx的配置，实现访问url的优化

[root@nginx ~]# vi /usr/local/nginx/conf/nginx.conf
     56         location /shopping {
     57                 rewrite ^/(.*) http://192.168.100.101/login.jsp permanent;
     58         }
[root@nginx ~]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@nginx ~]# /usr/local/nginx/sbin/nginx -s reload
