news 2025/8/30 3:58:31

---------------------Nginx+Tomcat负载均衡、动静分离-------------------------
Nginx 服务器：192.168.80.10:80
Tomcat服务器1：192.168.80.100:80
Tomcat服务器2：192.168.80.101:8080 192.168.80.101:8081

1.部署Nginx 负载均衡器
systemctl stop firewalld
setenforce 0

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

useradd -M -s /sbin/nologin nginx

cd /opt
tar zxvf nginx-1.12.0.tar.gz -C /opt/

cd nginx-1.12.0/
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-file-aio \                                   #启用文件修改支持
--with-http_stub_status_module \                   #启用状态统计
--with-http_gzip_static_module \                   #启用 gzip静态压缩
--with-http_flv_module \                           #启用 flv模块，提供对 flv 视频的伪流支持
--with-http_ssl_module                               #启用 SSL模块，提供SSL加密功能
--with-stream                                       #启用 stream模块，提供4层调度
----------------------------------------------------------------------------------------------------------
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-file-aio --with-http_stub_status_module --with-http_gzip_static_module --with-http_flv_module --with-stream

make && make install

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/

vim /lib/systemd/system/nginx.service
[Unit]
Description=nginx
After=network.target
[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStart=/usr/local/nginx/sbin/nginx
ExecrReload=/bin/kill -s HUP $MAINPID
ExecrStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target

chmod 754 /lib/systemd/system/nginx.service
systemctl start nginx.service
systemctl enable nginx.service

2.部署2台Tomcat 应用服务器
systemctl stop firewalld
setenforce 0

tar zxvf jdk-8u91-linux-x64.tar.gz -C /usr/local/

vim /etc/profile
export JAVA_HOME=/usr/local/jdk1.8.0_91
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin:$PATH

source /etc/profile

tar zxvf apache-tomcat-8.5.16.tar.gz

mv /opt/apache-tomcat-8.5.16/ /usr/local/tomcat

/usr/local/tomcat/bin/shutdown.sh
/usr/local/tomcat/bin/startup.sh

netstat -ntap | grep 8080

3.动静分离配置
（1）Tomcat1 server 配置
mkdir /usr/local/tomcat/webapps/test
vim /usr/local/tomcat/webapps/test/index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head>
<title>JSP test1 page</title> #指定为 test1 页面
</head>
<body>
<% out.println("动态页面 1,http://www.test1.com");%>
</body>
</html>
