Modify the hostname, permanently:
hostnamectl set-hostname hostname
Nginx installation:
1. Installation preparation
First of all, because some modules of nginx depend on some lib libraries, these lib libraries must be installed before installing nginx. These dependent libraries mainly include g++, gcc, openssl-devel, pcre-devel and zlib-devel, so execute the following command to install
yum install gcc-c++
yum install pcre pcre-devel
yum install zlib zlib-devel
yum install openssl openssl--devel
2. Install Nginx
Before installing, it is best to check if nginx is already installed
find -name nginx
If the system has already installed nginx, then uninstall it first
yum remove nginx
First go to the /usr/local directory
cd /usr/local
Download the latest version of nginx from the official website
wget http://nginx.org/download/nginx-1.11.5.tar.gz
tar -zxvf nginx-1.11.5.tar.gz
cd nginx-1.11.5
Next install, use the --prefix parameter to specify the directory where nginx is installed, make, make install install
./configure -- with - http_ssl_module $ default installed in /usr/local/nginx configure ssl https
make
make install
If there is no error, after the successful completion, it is best to look at the installation directory of nginx
whereis nginx
After the installation is complete, enter the post-installation directory (/usr/local/nginx) to start or stop it
start nginx
cd /usr/local/nginx/sbin
./nginx
Check the port status
netstat -nupl (UDP type port)
netstat -ntpl (TCP type port)
