1.反向代理
1.1反向代理 是指代理服务器来接收Internet上的客户端请求然后将请求转发给内部网络上的服务器并将从服务器上得到的结果返回给客户端。此时代理服务器对外就表现为一个反向代理服务器。 反向代理客户端不知道服务器的信息隐藏了服务器的信息
1.2正向代理是一个位于客户端和原始服务器之间的服务器为了从原始服务器获得内容。客户端向代理发送一个请求并指定目标原始服务器然后代理向原始服务器转发并获得的内容返回给客户端 正向代理服务器不知道客户端的信息隐藏了客户端的信息

1.案例1
1.1实现思路 1.2实现步骤 1.2.1Nginx配置
#配置文件中修改
vim /usr/local/nginx/conf/nginx.conf
server {listen 80;server_name 10.10.100.222;#charset koi8-r;#access_log logs/host.access.log main;location / {proxy_pass http://127.0.0.1:8080;root html;index index.html index.htm;}#检测语法是否正确
[rootlocalhost sbin]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful#重新加载nginx
[rootlocalhost ~]# /usr/local/nginx/sbin/nginx -s reload1.2.2搭建tomcat tomcat包和jdk包 链接https://pan.baidu.com/s/12n0LNdXiXIJh-GNQwp2WNw 提取码7ptr –来自百度网盘超级会员V1的分享 链接https://pan.baidu.com/s/1yuBmzZ76QShBfBnrrgDLfA 提取码hk96 –来自百度网盘超级会员V1的分享 安装jdk环境
#先创建java文件目录如果已存在就不用创建
mkdir -p /usr/local/java#解压到java文件目录
tar -vzxf jdk-8u161-linux-x64.tar.gz -C /usr/local/java/#配置环境变量
vi /etc/profile
export JAVA_HOME/usr/local/java/jdk1.8.0_11
export CLASSPATH$CLASSPATH:$JAVA_HOME/lib/
export PATH$PATH:$JAVA_HOME/bin#生效环境变量
source /etc/profile下载Tomcat、解压Tomcat、安装Tomcat、启动Tomcat
#解压tomcat
tar -zxvf apache-tomcat-9.0.78.tar.gz#安装tomcat
mv apache-tomcat-9.0.78 /usr/local/tomcat#启动tomcat
/usr/local/tomcat/bin/startup.sh1.3测试 可以看到tomcat的界面实际上是访问ngnix跳转到tomcat的8080端口
2.案例2
2.1实现思路 2.2实现步骤
#修改配置文件
server {listen 80;server_name 10.10.100.222;#charset koi8-r;#access_log logs/host.access.log main;location ~/aaa/ {proxy_pass http://127.0.0.1:8080;}location ~/bbb/ {proxy_pass http://127.0.0.1:8081;}
}#重新加载nginx
/usr/local/nginx/sbin/nginx -s reload2.2.1拷贝两个Tomcat将其中一个的端口信息修改为8081
#拷贝两个tomcattar -zxvf apache-tomcat-9.0.78.tar.gzmv apache-tomcat-9.0.78 /usr/local/tomcat1tar -zxvf apache-tomcat-9.0.78.tar.gzmv apache-tomcat-9.0.78 /usr/local/tomcat2#删除tomcat2下面的配置
rm -f /usr/local/tomcat2/conf/server.xml#添加新配置文件
vi /usr/local/tomcat2/conf/server.xml
