分布式集群环境下,如何实现session共享三(环境搭建)

  这是分布式集群环境下,如何实现session共享系列的第三篇。在上一篇:分布式集群环境下,如何实现session共享二(项目开发)中,准备好了一个通过原生态的servlet操作session的案例。本篇需要搭建相关的环境,包括:tomcat、nginx、redis。

  1.通过两个tomcat搭建集群:tomcat_1、tomcat_2

  2.通过nginx实现负载均衡

  3.通过redis存储session

1.安装tomcat

  1.1.tomcat_1

  上传tomcat_1到服务器192.168.80.22中。

#跳转到目录
cd /usr/local/develop

#创建目录
mkdir atomcat

cd atomcat

 

   server.xml配置文件(端口):

进程监听端口:
    <Server port="8005" shutdown="SHUTDOWN">
http服务端口:
       <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
集群通信端口:
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

 

  1.2.tomcat_2

  上传tomcat_2到服务器192.168.80.22中。

#跳转到目录
cd /usr/local/develop

#创建目录
mkdir atomcat

cd atomcat

 

   server.xml配置文件(端口):

进程监听端口:
    <Server port="8006" shutdown="SHUTDOWN">
http服务端口:
       <Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
集群通信端口:
    <Connector port="8010" protocol="AJP/1.3" redirectPort="8443" />

 

2.安装nginx

  2.1.安装编译工具和库文件

yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

 

  2.2.安装pcre

#进入目录
cd /usr/local/develop/anginx

#上传安装文件并解压
tar -zxvf pcre-8.38.tar.gz

#进入安装目录
cd pcre-8.38

#检查配置
./configure

#编译、安装
make && make install

#查看pcre版本
pcre-config --version

 

  2.3.安装nginx

#进入目录
cd /usr/local/develop/anginx

#上传安装文件,并解压
tar -zxvf nginx-1.8.1.tar.gz

#进入安装目录
cd nginx-1.8.1

#检查配置
./configure --prefix=/usr/local/develop/anginx/webserver/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/develop/anginx/pcre-8.38

#编译安装
make && make install

#查看nginx版本
 /usr/local/develop/anginx/webserver/nginx/sbin/nginx -v
--------------------------------------------------------
[root@hadoop02 webserver]# /usr/local/develop/anginx/webserver/nginx/sbin/nginx -v
nginx version: nginx/1.8.1

#配置nginx(检查)
/usr/local/develop/anginx/webserver/nginx/sbin/nginx -t

#nginx管理命令
/usr/local/develop/anginx/webserver/nginx/sbin/nginx              # 启动 Nginx
/usr/local/develop/anginx/webserver/nginx/sbin/nginx -s stop              # 停止 Nginx
/usr/local/develop/anginx/webserver/nginx/sbin/nginx -s reload            # 重新载入配置文件
/usr/local/develop/anginx/webserver/nginx/sbin/nginx -s reopen            # 重启 Nginx

 

  2.4.nginx基础配置

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

       

}

 

  2.4.nginx负载均衡配置

#添加tomcat列表,真实应用服务器都放在这
upstream tomcat_pool{
        #server tomcat地址:端口号 weight表示权值,权值越大,被分配的几率越大;
        server 192.168.80.22:8080 weight=4 max_fails=2 fail_timeout=30s;
        server 192.168.80.22:8081 weight=4 max_fails=2 fail_timeout=30s;
        
        #均衡策略
        #ip_hash;
}
---------------------------------------------------------------------------
 server {
        listen       80;
        server_name  tomcat_pool;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            #root   html;
            #index  index.html index.htm;
            proxy_pass http://tomcat_pool;    #转向tomcat处理
            proxy_set_header   Host             $host;
            proxy_set_header   X-Real-IP        $remote_addr;
            proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
        }

        #error_page  404              /404.html;
        
        .....................................................
   }

 

3.安装redis

  

#进入目录
cd /usr/local/develop/aredis

#上传并解压redis
tar -zxvf redis-3.2.11.tar.gz

#进入redis目录
cd redis-3.2.11

#编译
make

#进入src目录,并执行安装
cd src

make install PREFIX=/usr/local/develop/aredis/myredis

#启动redis服务端
[root@hadoop02 bin]# ./redis-server 

#客户端连接操作
[root@hadoop02 bin]# ./redis-cli
