환경 준비
1. nginx 서버 ip192.168.1.133 포트 81 준비
설치 과정:
＃首先安装依赖： yum -y install gcc-c++ yum -y install pcre pcre-devel yum -y install zlib zlib-devel yum -y install openssl openssl—devel #注意 ： 安装nginx必须使用 root 用户安装 #创建一个nginx目录 mkdir /usr/local/src/nginx #进入到nginx目录 cd /usr/local/src/nginx #下载或上传安装包 wget http://nginx.org/download/nginx.tar.gz 或 rz上传 #解压安装包 tar -xvf nginx.tar.gz #进入到解压后的目录 cd nginx # 下面 才开始正式安装 #把nginx安装到指定用户的目录 mkdir -p /ucenter/soft/nginx #安装配置 prefix为安装目录 user为用户 group为 组 ./configure --prefix=/ucenter/soft/nginx --user=ucenter --group=ucenter #编译 make #安装 make install #在linux系统中由于非root用户不能占用80端口，所以需要使普通用户以root身份启动nginx。 cd /ucenter/soft/nginx/sbin #把soft文件下所有的文件所属者修改为ucener -r 表示递归 chown ucenter:ucenter ./soft/ -r #修改 ./nginx 的所属为root chown root nginx #让普通用户可以使用80端口，可以使用root权限启用nginx chmod u+s nginx #修改配置文件 在修改配置文件之前 ，要备份该文件 cd conf/ # 要注意nginx 的工作进程，一般根据cpu的核数去修改 vim nginx.conf #关闭防火墙，打开80端口 service iptables stop #启动nginx ./nginx #重启nginx ./nginx -s reload #关闭nginx ./nginx -s stop

Tomcat 서버 준비, 먼저 Java 환경 준비, jdk 설치 단계는 생략
그런 다음 각각 3개의 Tomcat 서버 IP 주소(192.168.1.143, tomcat1 8080 포트, tomcat2 8081 포트 및 tomcat3 8082 포트)를 설치합니다.
apache-tomcat-7.0.64/conf/server.xml 구성 파일 포트가 충돌하지 않도록 이 세 곳을 수정하세요
<server port="8005" shutdown="shutdown"> <connector port="8080" protocol="http/1.1" connectiontimeout="20000" redirectport="8443" /> <connector port="8009" protocol="ajp/1.3" redirectport="8443" />
로그인 후 복사
Tomcat 루트 디렉터리의 index.jsp를 수정하고 각 Tomcat 로고를 별도로 추가하세요. , 그리고 페이지에 세션 ID를 표시합니다
