nginx+tomcat で Redis セッション共有を使用する方法
redis
nginx
tomcat
環境の準備
1. nginx サーバー ip192.168.1.133 ポート 81 を準備します
インストール プロセス:
＃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 サーバーを準備します。最初に Java 環境を準備し、JDK インストール手順を省略します。
次に、3 つの Tomcat サーバー IP アドレスをインストールします: 192.168.1.143、tomcat1 ポート 8080、tomcat2 8081 ポート、tomcat3 ポート 8082 。
apache-tomcat-7.0.64/conf/server.xml 設定ファイル ポートが競合しないように、これら 3 つの場所を変更します。
<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" />
ログイン後にコピー
Tomcat ルート ディレクトリの Index.jsp を変更し、各 Tomcat の ID を追加し、ページにセッション ID を表示します
