准备：
- linux版本：CentOS7.4 64位
- 以下操作全部在root账号下进行
- 已经在腾讯云上进行备案的域名一枚，如何解析，请参看腾讯云 .cn域名解析配置讲解 域名绑定 泽0715 新浪博客
一、环境
jdk-1.8
nginx-1.12.1
tomcat-7.0.79
jdk与nginx版本
1、防火墙开通80和443端口，参看CentOS7.x之防火墙
2、腾讯云安全组开放80和443端口
腾讯云服务器安全组开放80个443端口
二、JDK1.8安装
三、Tomcat安装
#如果没有此目录，则创建
cd /usr/local/tomcat
#下载tomcat-7.0.79
wget http://archive.apache.org/dist/tomcat/tomcat-7/v7.0.79/bin/apache-tomcat-7.0.79.tar.gz
#解压并重命名分别为tomcat-7.0.79_01、tomcat-7.0.79_02（server.conf中的端口下文有详细配置）
tar -xzvf apache-tomcat-7.0.79.tar.gz
四、Web项目
1、tomcat-7.0.79_01中的WebProject项目index.jsp内容
WebProject01中的jsp内容
tomcat-7.0.79_01中的server.conf配置如下

3、server.conf配置不同之处有四
#1_01
<Server port="8005" shutdown="SHUTDOWN">
#1_02
<Server port="8006" shutdown="SHUTDOWN">
#2_01
<Connector port="8080" protocol="HTTP/1.1" URIEncoding="UTF-8"
connectionTimeout="20000"
redirectPort="8443" />
#2_02
<Connector port="8081" protocol="HTTP/1.1" URIEncoding="UTF-8"
connectionTimeout="20000"
redirectPort="8444" />
#3_01
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
#3_02
<Connector port="8010" protocol="AJP/1.3" redirectPort="8444" />
#4_01
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<Context path="" docBase="/usr/local/tomcat/tomcat7/tomcat-7.0.79_01/webapps/WebProject" reloadable="true" crossContext="true" />
#4_02
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<Context path="" docBase="/usr/local/tomcat/tomcat7/tomcat-7.0.79_02/webapps/WebProject" reloadable="true" crossContext="true" />
说明：
- 将WebProject项目在Eclipse或者MyEclipse中打成war包上传至tomcat启动目录中，tomcat启动一次后，会自动解压war包，将tomcat关闭后，即可删除war包
- 将两个tomcat分别启动
五、Nginx安装
1、下载、解压
cd /usr/local/src
wget http://nginx.org/download/nginx-1.12.1.tar.gz #稳定版
tar nginx-1.12.1.tar.gz
cd nginx-1.12.1
2、安装准备
yum install gcc gcc-c++ -y #安装gcc和c++包
yum -y install pcre pcre-devel zlib-devel openssl-devel
3、安装Nginx
cd /usr/local/src/nginx-1.12.1
#安装到指定目录
./configure --prefix=/usr/local/nginx/ --with-http_stub_status_module --with-http_ssl_module
#编译
make && make install
- --prefix=/usr/local/nginx/ #nginx安装的根目录
- --with-http_stub_status_module #监控nginx运行状态
- --with-http_ssl_module #添加ssl模块
有关nginx参数详解，请参考nginx安装及编译参数详解
4、 nginx.conf参数配置（图文）
nginx.conf配置参数_01
nginx.conf配置参数_02
xxx.cn全部以你申请的域名替换
#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;

}

access_log logs/jmszwzr.access.log main;
error_log logs/jmszwzr.error.log;
#rewrite ^(.*) https://$server_name$1 permanent;
#弃用rewrite，使用return效率更高
return 301 https://$server_name$request_uri;
location / {
proxy_pass http://tomcat7_cluster;
}
}
# HTTPS server
server {
listen 443 ssl;
#server_name www.xxx.cn;
server_name localhost;
#ssl on;
access_log logs/ssl.access.log main;
error_log logs/ssl.error.log;
#为虚拟主机指定pem格式的证书文件
ssl_certificate 1_www.xxx.cn_bundle.crt;
#为虚拟主机指定私钥文件
ssl_certificate_key 2_www.xxx.cn.key;
#ssl_session_cache shared:SSL:1m;
#客户端能够重复使用存储在缓存中的会话参数时间
ssl_session_timeout 10m;
#指定使用的ssl协议
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
#指定许可的密码描述
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
#SSLv3和TLSv1协议的服务器密码需求优先级高于客户端密码
ssl_prefer_server_ciphers on;
location / {
proxy_pass http://tomcat7_cluster;
}
}
}
配置好nginx.conf文件之后，可以进行验证配置是否正确
配置nginx.conf是否正确
#在nginx根目录下
./sbin/nginx #启动nginx
./sbin/nginx -s reload #软重启
六、浏览器访问
访问两个项目的几率可在nginx中配置
第一次访问
第二次访问
结尾：以上只是简单的将nginx作为反向代理服务器，配以https加密访问，实际情况中，还有很多需要添加的模块和优化的地方。如tomcat集群下的session共享、nginx优化等问题。
小白初入，如有错误，欢迎各位简友指正，在此感谢！
