nginx备忘录

安装

rpm (离线)

直接进nginx下载包页面
选择你要的版本连接

wget https://nginx.org/packages/centos/7/x86_64/RPMS/nginx-1.20.2-1.el7.ngx.x86_64.rpm
rpm -ivh nginx-1.20.2-1.el7.ngx.x86_64.rpm
systemctl start nginx
systemctl status nginx
nginx -V

yum (rhel/centos)

yum -y install nginx

apt (debian/ubuntu)

apt update
apt install nginx

反向代理

先安装Tomcat测试tomcat下载页面
JDKjdk下载页面

wget https://dlcdn.apache.org/tomcat/tomcat-9/v9.0.74/bin/apache-tomcat-9.0.74.tar.gz
tar -zxvf apache-tomcat-9.0.74.tar.gz
mkdir /usr/tomcat
mv apache-tomcat-9.0.74 /usr/tomcat
cd /usr/tomcat/apache-tomcat-9.0.74/bin
./startup.sh
ss -ntl #查看tomcat端口，默认8080

修改配置文件
添加反向代理server块

#vim /etc/nginx/nginx.conf
server{
	listen		81;
	location / {
	proxy_pass		http://127.0.0.1:8080;
	}
}

输入你的nginx主页面地址加上:81 就能出现tomcat页面
