1.安装tomcat请参考：[https://blog.csdn.net/qq\_32784303/article/details/80366962][https_blog.csdn.net_qq_32784303_article_details_80366962]

2.复制两个tomcat出来，将其中一个端口号更改（usr/local/tomcat/tomcat1/conf/service.xml）

3.启动两个tomcat

4.安装nginx：

4.1.安装make：

yum -y install gcc automake autoconf libtool make

安装g++:

yum install gcc gcc-c++

4.2：**选定安装文件目录**

cd /usr/local/src

4.3：**安装PCRE库**

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.39.tar.gz 
    tar -zxvf pcre-8.39.tar.gz
    cd pcre-8.39
    ./configure
    make
    make install

4.4：**安装zlib库**

cd /usr/local/src
     
    wget http://zlib.net/zlib-1.2.11.tar.gz
    tar -zxvf zlib-1.2.11.tar.gz
    cd zlib-1.2.11
    ./configure
    make
    make install

4.5：**安装openssl（某些vps默认没装ssl)**

cd /usr/local/src
    wget https://www.openssl.org/source/openssl-1.0.1t.tar.gz
    tar -zxvf openssl-1.0.1t.tar.gz

4.6：**安装nginx**

cd /usr/local/src
    wget http://nginx.org/download/nginx-1.1.10.tar.gz
    tar -zxvf nginx-1.1.10.tar.gz
    cd nginx-1.1.10
    ./configure
    make
    make install

这里安装如果报错

![70][]

请执行：

yum -y install openssl openssl-devel

4.7：更改nginx端口号为8089

vi /usr/local/nginx/conf/nginx.conf

![70 1][]

4.8：启动nginx

方式一：/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

方式二：/usr/local/nginx/sbin/nginx -t

查看启动的nginx端口：

netstat -ano|grep 8089

4.9：停止nginx

kill -QUIT 2072（2072为ps -ef|grep nginx查询出的nginx进程pid）

pkill -9 nginx（为强制停止）

5.配置nginx.conf实现反向代理

![70 2][]

6.启动nginx

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

7.浏览器访问会在两个tomcat之间来回切换
