Because php installation requires compilation, the server should ensure the installation of gcc and g++ environments
1. First release the installation package:
tar -xvzf php-7.0.5.tar.gz cd php-7.0.5
2. Next, configure the parameters. If there is no libxml2 and libxml2-devel before configuration, an error will be reported, so you should update libxml2 and install libxml2-devel, using online installation:
yum -y install libxml2 yum -y install libxml2-devel
Because different operating system environments have different degrees of completeness of the system installation development environment package, it is recommended to make necessary choices when installing the operating system. You can also execute all the commands in a unified manner to install the components that are not installed. It may be upgraded if the version is completely consistent, and no operation will be performed if the version is exactly the same. Except for the above two commands, the summary is as follows:
yum -y install openssl yum -y install openssl-devel yum -y install curl yum -y install curl-devel yum -y install libjpeg yum -y install libjpeg-devel yum -y install libpng yum -y install libpng-devel yum -y install freetype yum -y install freetype-devel yum -y install pcre yum -y install pcre-devel yum -y install libxslt yum -y install libxslt-devel yum -y install bzip2 yum -y install bzip2-devel
The above packages are basically enough. If you find any problems, add them. After the installation is complete, execute the configuration:
./configure --prefix=/usr/local/php --with-curl --with-freetype-dir --with-gd --with-gettext --with-iconv-dir --with-kerberos --with-libdir=lib64 --with-libxml-dir --with-mysqli --with-openssl --with-pcre-regex --with-pdo-mysql --with-pdo-sqlite --with-pear --with-png-dir --with-jpeg-dir --with-xmlrpc --with-xsl --with-zlib --with-bz2 --with-mhash --enable-fpm --enable-bcmath --enable-libxml --enable-inline-optimization --enable-gd-native-ttf --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-sysvshm --enable-xml --enable-zip
In fact, there are more configuration items here than the above. You can use the ./configure --help command to view all options. Note that in php7, the --with-mysql native support no longer exists, and the operations have become mysqli or pdo; The above options are completely sufficient in normal php development. Later, if necessary, you can choose to manually open the corresponding module
3. Then execute the compilation:
make
The compilation time may be a bit long. After the compilation is completed, execute the installation:
make install
4. The default installation location of php has been specified as /usr/local/php, and then configure the corresponding files:
cp php.ini-development /usr/local/php/lib/php.ini cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf cp cow/fpm/php-fpm /usr/local/bin
5. Then set php.ini, use: vim /usr/local/php/lib/php.ini Open the php configuration file and find the cgi.fix_pathinfo configuration item, which is commented by default and has a value of 1, according to the official documentation , here in order to prevent Nginx from sending requests to the PHP-FPM module of the backend when the file does not exist, so as to avoid malicious script injection attacks, so this item should be uncommented and set to 0
Save and exit after setting
6. Another thing to note is that the location of the php.ini configuration file can be set in the configuration parameters before compilation. The compilation parameters can be written as: --with-config-file-path=/usr/local/php In this case, php will go back and specify Read the php.ini configuration file in the directory of php.ini. If you do not add this parameter, the default location is the lib directory under the php installation directory. You can also view it in the phpinfo() output interface. If php.ini is placed in another location, php reads If not, then all configuration modifications will not take effect, please pay attention to this
At this point you should first create a web user:
groupadd www-data useradd -g www-data www-data
Then some tutorials on the Internet say to modify php-fpm.conf to add the users and groups created above. At this time, use vim /usr/local/php/etc/php-fpm.conf to open the file and can't find the location suggested by the official:
If you add it in any location at this time, then when you start php-fpm next, it will report an error that the directory cannot be found, so don't add users and groups to php-fpm.conf, and turn to php-fpm at this time. The last line of conf will find the following content (if the --prefix option is added when compiling, the following position will be automatically completed, the default is empty below, pay attention):
All the conf configuration files in the php-fpm.d directory are introduced here, but NONE needs to be modified to our actual directory: /usr/local
By default, there is a file called www.conf.defalut under etc/php-fpm.d/ for configuring users. Execute the following command to copy a new file and open it:
cp /usr/local/etc/php-fpm.d/www.conf.default /usr/local/etc/php-fpm.d/www.conf vim /usr/local/etc/php-fpm.d/www.conf
The default user and group settings are nobody, change them to www-data
After the modification is complete, save and exit, and then execute the following command to start the php-fpm service:
/usr/local/bin/php-fpm
After startup, the php-fpm service uses port 9000 by default. Use netstat -tln | grep 9000 to view the port usage:
Port 9000 is in normal use, indicating that the php-fpm service is successfully started
7. Then execute vim /usr/local/nginx/nginx.conf to edit the nginx configuration file. The specific path is edited according to the actual location of the nginx.conf configuration file. The following mainly modifies the content in the server {} configuration block of nginx and modifies the location block , append index.php to make the nginx server support index.php as the home page by default:
Then the configuration.php request is sent to the php-fpm module on the backend. By default, the php configuration block is commented. At this time, remove the comment and modify it to the following:
8. Many of them are default. root is the root directory where the php program is configured. The main modification is that /scripts in fastcgi_param is $document_root
After modifying the above, go back to the first line of nginx.conf, the default is #user nobody; here you need to remove the comment and change it to user www-data; or user www-data www-data; indicates that the authority of the nginx server is www-data
After modifying these save and exit, then restart nginx:
/usr/local/nginx/nginx -s stop /usr/local/nginx/nginx
9. Next, edit a test php program, create a test.php file in the html directory under nginx, and print the php configuration:
<?php
phpinfo();
?>
