lnmt 简介
lnmt： 表示的是 linux + nginx + mysql + tomcat 的简称
Apache 为HTML页面服务，而Tomcat实际上运行JSP页面和Servlet，Tomcat实际上运行JSP页面和Servlet，Tomcat处理静态HTML的能力不如Apache服务器

在 tomcat-server 服务器上，安装tomcat
java环境安装
安装jdk 环境
[root@tomcat-server ~]# yum -y install java-1.8.0-openjdk java-1.8.0-openjdk-devel 查看安装的版本
[root@tomcat-server ~]# java -version
openjdk version "1.8.0_181"
OpenJDK Runtime Environment (build 1.8.0_181-b13)
OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)tomcat 部署
下载tomcat
[root@tomcat-server ~]# cd /usr/src/
[root@tomcat-server src]# yum install -y wget vim
[root@tomcat-server src]# wget https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.8/bin/apache-tomcat-9.0.8.tar.gz解压部署tomcat
[root@tomcat-server src]# tar xf apache-tomcat-9.0.8.tar.gz -C /usr/local/
[root@tomcat-server src]# cd /usr/local/
[root@tomcat-server local]# ln -s apache-tomcat-9.0.8/ tomcat写一个’chens’的java 页面
[root@tomcat-server local]# cd /usr/local/tomcat/webapps/ROOT/
[root@tomcat-server ROOT]# mv index.jsp /opt/ //默认tomcat 访问的就是ROOT目录下的index.jsp
[root@tomcat-server ROOT]# vim index.jsp
<html>
<head>
<title> test page</title>
</head>
<body>
<%
out.println("chens");
%>
</body>
</html>启动tomcat
[root@tomcat-server ROOT]# /usr/local/tomcat/bin/catalina.sh start

配置第二个tomcat 服务
[root@tomcat-server ~]# cd /usr/local/
[root@tomcat-server local]# mkdir chens
[root@tomcat-server local]# cd /usr/src/
[root@tomcat-server src]# tar xf apache-tomcat-9.0.8.tar.gz -C /usr/local/chens/
[root@tomcat-server src]# cd /usr/local/
[root@tomcat-server local]# ln -s chens/apache-tomcat-9.0.8/ tomcat2由于服务相同，会产生端口被占用的情况，所以需要修改tomcat2 的端口
[root@tomcat-server ~]# vim /usr/local/tomcat2/conf/server.xml
<Server port="8015" shutdown="SHUTDOWN"> //这个地方改为8015端口
<Listener className="org.apache.catalina.startup.VersionLoggerListener" />
<Connector port="8050" protocol="HTTP/1.1" //这个地方改为8050端口
connectionTimeout="20000"
redirectPort="8443" />
<Connector port="8019" protocol="AJP/1.3" redirectPort="8443" /> //这个地方改为8019端口重启tomcat 服务
[root@tomcat-server ROOT]# /usr/local/tomcat/bin/catalina.sh stop
[root@tomcat-server ROOT]# /usr/local/tomcat/bin/catalina.sh start在nginx-server服务器上对nginx 进行配置
在 nginx 上配置反向代理 和 负载均衡实现动静分离
[root@nginx-server ~]# vim /usr/local/nginx/conf/nginx.conf
#gzip on;
upstream web { 实现负载
server 192.168.169.20:8080;
server 192.168.169.20:8050;
}
server {
listen 80;
server_name localhost;
access_log logs/host.access.log main;
location ~ .*$ { 其他的文件交给tomcat去处理
index index;
proxy_pass http://web;
}
location \ { 静态的文件交给nginx本身去处理
root html;
index index.jsp index.html index.htm;
}
重新加载nginx配置
[root@nginx-server ~]# nginx -s reload在浏览器上测试，出现以下效果则成功
输入nginx 服务器的IP地址
再次访问或者刷新
