1.安装Tomcat

进入 /usr/local/ 目录 cd /usr/local

下载 wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-9/v9.0.22/bin/apache-tomcat-9.0.22.tar.gz

解压 tar -zxvf apache-tomcat-9.0.22.tar.gz

新建文件夹 mkdir tomcat-9.0.22

重命名 mv ./apache-tomcat-9.0.22 ./tomcat-9.0.22/tomcat1

解压 tar -zxvf apache-tomcat-9.0.22.tar.gz

重命名 mv ./apache-tomcat-9.0.22 ./tomcat-9.0.22/tomcat2

2.配置Tomcat

添加环境变量 vim /etc/profile　

export CATALINA_HOME=/usr/local/tomcat-9.0.21/tomcat1
export CATALINA_BASE=/usr/local/tomcat-9.0.21/tomcat1
export TOMCAT_HOME=/usr/local/tomcat-9.0.21/tomcat1

export CATALINA_2_HOME=/usr/local/tomcat-9.0.21/tomcat2
export CATALINA_2_BASE=/usr/local/tomcat-9.0.21/tomcat2
export TOMCAT_2_HOME=/usr/local/tomcat-9.0.21/tomcat2

打开tomcat2/bin下的catalina.sh文件vim /usr/local/tomcat-9.0.22/tomcat2/bin/catalina.sh，在# OS specific support.  $var _must_ be set to either true or false.下增加

export CATALINA_BASE=$CATALINA_2_BASE
export CATALINA_HOME=$CATALINA_2_HOME

打开tomcat2/conf下的server.xml文件vim /usr/local/tomcat-9.0.22/tomcat2/conf/server.xml，修改端口，避免启动服务器端口冲突

 　　

　　用一张png图片替换tomcat1/webapps/ROOT/下的tomcat.png图片，以区分两个服务器

　　分别启动两个tomcat，

cd /usr/local/tomcat-9.0.22/tomcat1/bin/  

./startup.sh

cd /usr/local/tomcat-9.0.22/tomcat2/bin/  

 ./startup.sh

请求测试对应的服务器

tomcat1：

tomcat2：

3.安装Nginx

yum install nginx

4.配置Nginx

vim /etc/nginx/nginx.conf

# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/
#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;
 # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    #include /etc/nginx/conf.d/*.conf;

    upstream tomcat9{
        server IP地址:8080 weight=2;
        server IP地址:9080 weight=2;
    }

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  请求地址;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {
                proxy_pass http://tomcat9;
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
}

启动Nginx

cd /bin

./systemctl strat nginx
