通过Nginx解决网络隔离实践记录详解

# 下载
[work@40-10-14 opt]$ wget http://nginx.org/download/nginx-1.18.0.tar.gz
# 解压文件
[work@40-10-14 opt]$ tar -xvf nginx-1.18.0.tar.gz

# 1. 默认安装：root权限进入解压后的目录，执行如下命令安装
[root@40-10-14 nginx-1.18.0]# ./configure && make && make install

# 2.指定目录：安装到指定的/opt/nginx目录
[work@40-10-14 opt]$ mkdir /opt/nginx
[work@40-10-14 nginx-1.18.0]$ ./configure --prefix=/opt/nginx && make && mae install

mkdir: cannot create directory `/usr/local/nginx': Permission denied
make[1]: *** [install] Error 1
make[1]: Leaving directory `/opt/nginx-1.18.0'
make: *** [install] Error 2
