nginx web
(the difference between this web service software and apache: Nginx is a lightweight service software, the biggest feature is to support very large concurrent access)
The advantage of Nginx lies in its stability, low system resource consumption, and high concurrent connections Processing capacity
-a physical server can handle 30,000 to 50,000 concurrent requests
Disc replacement (depending on the situation)
Uninstall the first CD (execute twice to make sure it has been uninstalled)
umount /dev/cdrom
Physical swap
Mount manually:
mount /dev/cdrom/media/
Confirm whether it has been mounted
cd / media /
ls
Modify yum source path
vim /etc/yum.repos.d/dvd.repo
Point it directly to media
Install Nginx
-Make sure that the development environment software package exists before compiling and installing
yum -y install pcre-devel zlib-devel (adding the y option will automatically install it for you)
-Create running users and groups
useradd -M -s /sbin/nologin nginx (create a program user, -M do not add a directory, -s specify a path) do not need a home directory, do not log
in. Problems encountered: useradd: cannot open /etc/passwd
Solution: https: //www.cnblogs.com/detector/p/7850099.html

Start nginx:
./nginx
Verify that the service is started, check port 80
ss -antpl | grep 80

Nginx implements php parsing
Nginx does not recognize PHP language by default
Install php parsing environment
Installation package:

--enable-fpm FastCGI process manager is used to manage php parsing instances to optimize parsing efficiency
Verify that the installation is successful
cd /usr/local/php5/bin/
