CentOS 7 install Nginx, PHP7, PHP-FPM

Install nginx
CentOS 7 has no built-in nginx, so first go to the nginx official website http://nginx.org/en/linux_packages.html#stable, find CentOS 7 nginx-release package File link, and then install the following
Rpm-Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
After installation, the repository settings of yum are automatically generated (in/etc/yum. repos. d/nginx. repo ),
Then you can use the yum command to install nginx
Yum install nginx
Start nginx
Previously, chkconfig was used to manage services. CentOS 7 switched to systemctl management system services.
Start Now
Systemctl start nginx
View current operation status
Systemctl status nginx
View the current startup settings of the nginx service
Systemctl list-unit-files | grep nginx
If it is disabled, it can be changed to boot automatically
Systemctl enable nginx
If you have set a strong fire prevention, check the strong fire protection running status and check whether the port used by nginx is enabled.
Firewall-cmd -- state
Enable http services with strong fire prevention
Firewall-cmd -- permanent -- zone = public -- add-service = http
Firewall-cmd -- reload
List the setting of strong public in fire prevention
Firewall-cmd -- list-all -- zone = public
After the preceding settings, you can use a browser to access the nginx preset page.
Install PHP-FPM
Use yum to install php, php-fpm, and php-mysql
Yum install php-fpm php-mysql
View the current startup settings of the php-fpm service
Systemctl list-unit-files | grep php-fpm
Change to automatic start upon startup
Systemctl enable php-fpm
Start Now
Systemctl start php-fpm
View current operation status
Systemctl status php-fpm
How to modify the PHP-FPM listen
If you want to change the PHP-FPM listen method to unix socket, you can edit/etc/php-fpm.d/www. conf
Set
Listen = 127.0.0.1: 9000
Change
Listen =/var/execute/php-fpm/php-fpm.sock
Then restart php-fpm.
Systemctl restart php-fpm
Note: do not change to listen =/tmp/php-fcgi.sock (set the php-fcgi.sock under/tmp) because when the system generates a php-fcgi.sock, will be placed in the/tmp/systemd-private-*/tmp/php-fpm.sock random private directory, unless you change PrivateTmp = true in/usr/lib/systemd/system/to PrivateTmp = false, other problems still occur, so it is most convenient to change the location.

Delete previous versions

# Yum remove php *

Install the yum source corresponding to Php7 in rpm

CentOS/RHEL 7.x:

# Rpm-Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm # rpm-Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

Compile and install php7
Configure, make, and install)

Use configure -- help

You must specify the prefix for compiling and installation. This is the installation directory, which limits all files to this directory. You only need to delete the directory when uninstalling the directory. If this parameter is not specified, it will be installed in many places, it is inconvenient to delete the backend.

Configuration: -- cache-file = FILE cache test results in FILE -- help print this message -- no-create do not create output files -- quiet, -- silent do not print 'checking... 'messages -- version print the version of autoconf that created configure Directory and file names: -- prefix = PREFIX install architecture-independent files in PREFIX [/usr/local] -- exec-prefix = EPREFIX install architecture-dependent files in EPREFIX
Note:
An error occurs when the memory is smaller than 1 GB. A line of content is added after the compilation parameter -- disable-fileinfo

Other configuration parameters

-- Exec-prefix = EXEC-PREFIX
You can install system-related files in a different location, instead of PREFIX settings. This allows you to easily share system-related files between different hosts.
-- Bindir = DIRECTORY
Specifies the executable program declaration directory, which defaults to EXEC-PREFIX/bin.
-- Datadir = DIRECTORY
Set the Directory of the read-only files required by the installed program. The default value is PREFIX/share.
-- Sysconfdir = DIRECTORY
Used for directories of various configuration files. The default value is PREFIX/etc.
-- Libdir = DIRECTORY
Library file and directory of the dynamic Mount module. The default is EXEC-PREFIX/lib
-- Includedir = DIRECTORY
Directory of the C and C ++ header files. The default value is PREFIX/include.
-- Docdir = DIRECTORY
Document files (except man (manual page) will be installed in this directory. The default is PREFIX/doc
-- Mandir = DIRECTORY
The manual page that comes with the program will be installed in this directory. In their corresponding manx subdirectories, the default is PREFIX/man.
Note: to reduce pollution to shared installation locations (such as/usr/local/include), configure automatically attaches a "/postgresql" string to datadir, sysconfdir, includedir, and docdir, unless the expanded directory name already contains the string "s S" or "pgsql ". for example, if you select/usr/local as the prefix, the header file of C will be installed in/usr/local/include/postgresql, but if the prefix is/opt/postgres, then they will be put into/opt/S/include
-- With-nodes des = DIRECTORIES
DIRECTORIES is a series of colon-separated DIRECTORIES that will be added to the compiler's header file search list. if you have some optional packages (such as GNU Readline) installed in a non-standard Huai location, you must use this option and possibly have the corresponding -- with-libraries option.
-- With-libraries = DIRECTORIES
DIRECTORIES is a series of colon-separated DIRECTORIES used to find library files. if you have some packages installed in a non-standard location, you may need to use this option (and the corresponding -- with-provided des option)
-- Enable-XXX
Open XXX support
-- With-XXX
Create XXX module
