LNMP之Php的安装配置

此配置的编译参数是：

./configure --prefix=/opt/php7.2.3 --with-openssl --with-zlib --with-curl --enable-ftp --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --enable-mbstring --with-libxml-dir --enable-soap --enable-sockets --with-xmlrpc --with-iconv-dir=/opt/libiconv --with-xsl --with-mysqli --with-pdo-mysql --enable-zip --enable-fpm --with-fpm-user=USER --with-fpm-group=GRP

php的配置文件：

[root@cairui php]# cd etc/
[root@cairui etc]# ls
pear.conf  php-fpm.conf.default  php-fpm.d

注：对apache来说php是没有进程的，它只是一个模块，在服务配置文件中配置模块支持就可以了，但对于nginx来说，php是有进程的，而它是依靠fastcgi来运行，所以配置和apache的不同。

;;;;;;;;;;;;;;;;;;;;;
; FPM Configuration ;
;;;;;;;;;;;;;;;;;;;;;

; All relative paths in this configuration file are relative to PHP's install
; prefix (/opt/php7.1.15). This prefix can be dynamically changed by using the
; '-p' argument from the command line.

;;;;;;;;;;;;;;;;;;
; Global Options ;
;;;;;;;;;;;;;;;;;;

[global]
; Pid file
; Note: the default prefix is /opt/php7.1.15/var
; Default Value: none
;pid = run/php-fpm.pid

; Error log file
; If it's set to "syslog", log is sent to syslogd instead of being written
; into a local file.
; Note: the default prefix is /opt/php7.1.15/var
; Default Value: log/php-fpm.log
;error_log = log/php-fpm.log

; syslog_facility is used to specify what type of program is logging the
; message. This lets syslogd specify that messages from different facilities
; will be handled differently.
; See syslog() for possible values (ex daemon equiv LOG_DAEMON)
; Default Value: daemon
;syslog.facility = daemon

; syslog_ident is prepended to every message. If you have multiple FPM
; instances running on the same server, you can change the default value
; which must suit common needs.
; Default Value: php-fpm
;syslog.ident = php-fpm

; Log level
; Possible Values: alert, error, warning, notice, debug
; Default Value: notice
;log_level = notice

; If this number of child processes exit with SIGSEGV or SIGBUS within the time
; interval set by emergency_restart_interval then FPM will restart. A value
; of '' means 'Off'.
; Default Value:
;emergency_restart_threshold = 

; Interval of time used by emergency_restart_interval to determine when
; a graceful restart will be initiated.  This can be useful to work around
; accidental corruptions in an accelerator's shared memory.
; Available Units: s(econds), m(inutes), h(ours), or d(ays)
; Default Unit: seconds
; Default Value:
;emergency_restart_interval = 

; Time limit for child processes to wait for a reaction on signals from master.
; Available units: s(econds), m(inutes), h(ours), or d(ays)
; Default Unit: seconds
; Default Value:
;process_control_timeout = 

; The maximum number of processes FPM will fork. This has been designed to control
; the global number of processes when using dynamic PM within a lot of pools.
; Use it with caution.
; Note: A value of  indicates no limit
; Default Value:
; process.max = 

; Specify the nice() priority to apply to the master process (only if set)
; The value can vary from - (highest priority) to  (lowest priority)
; Note: - It will only work if the FPM master process is launched as root
;       - The pool process will inherit the master process priority
;         unless specified otherwise
; Default Value: no set

; Send FPM to background. Set to 'no' to keep FPM in foreground for debugging.
; Default Value: yes
;daemonize = yes

; Set open file descriptor rlimit for the master process.

;;;;;;;;;;;;;;;;;;;;
; Pool Definitions ;
;;;;;;;;;;;;;;;;;;;;

; Multiple pools of child processes may be started with different listening
; ports and different management options.  The name of the pool will be
; used in logs and stats. There is no limitation on the number of pools which
; FPM can handle. Your system will tell you anyway :)

; Include one or more files. If glob() exists, it is used to include a bunch of
; files from a glob() pattern. This directive can be used everywhere in the
; file.
; Relative path can also be used. They will be prefixed by:
;  - the global prefix if it's been set (-p argument)
;  - /opt/php7.1.15 otherwise

; This value sets the limit on the number of simultaneous requests that will be

; By default the status page output is formatted as text/plain. Passing either

;   http://www.foo.bar/status?json&full
;   http://www.foo.bar/status?html&full

;   last request cpu     - the %cpu the last request consumed
;                          it's always 0 if the process is not in Idle state
;                          because CPU calculation is done when the request

php官网的推荐安装：

Unix 系统下的 Nginx 1.4.x
本文档包括使用 PHP-FPM 为 Nginx 1.4.x HTTP 服务器安装和配置 PHP 的说明和提示。

本指南假定您已经从源代码成功构建 Nginx，并且其二进制文件和配置文件都位于 /usr/local/nginx。 如果您使用其他方式获取的 Nginx，请参考 » Nginx Wiki 并对照本文档完成安装。

本文档仅包含 Nginx 服务器的基本配置，它将通过 80 端口提供 PHP 应用的处理能力。 如果您需要超出本文档范围的安装配置指导，建议您查阅 Nginx 和 PHP-FPM 的文档。

需要注意的是，本文档一律使用 'x' 来表示版本号，请根据实际情况将 'x' 替换为对应的版本号。

建议您访问 Nginx Wiki » 安装 页面以获取并在您的系统上安装 Nginx。

获取并解压 PHP 源代码:

tar zxf php-x.x.x
配置并构建 PHP。在此步骤您可以使用很多选项自定义 PHP，例如启用某些扩展等。 运行 ./configure --help 命令来获得完整的可用选项清单。 在本示例中，我们仅进行包含 PHP-FPM 和 MySQL 支持的简单配置。

cd ../php-x.x.x
./configure --enable-fpm --with-mysql
make
sudo make install
创建配置文件，并将其复制到正确的位置。

cp php.ini-development /usr/local/php/php.ini
cp /usr/local/etc/php-fpm.conf.default /usr/local/etc/php-fpm.conf
cp sapi/fpm/php-fpm /usr/local/bin
需要着重提醒的是，如果文件不存在，则阻止 Nginx 将请求发送到后端的 PHP-FPM 模块， 以避免遭受恶意脚本注入的攻击。

将 php.ini 文件中的配置项 cgi.fix_pathinfo 设置为 0 。

打开 php.ini:

vim /usr/local/php/php.ini
定位到 cgi.fix_pathinfo= 并将其修改为如下所示：

cgi.fix_pathinfo=0
在启动服务之前，需要修改 php-fpm.conf 配置文件，确保 php-fpm 模块使用 www-data 用户和 www-data 用户组的身份运行。

vim /usr/local/etc/php-fpm.conf
找到以下内容并修改：

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
user = www-data
group = www-data
然后启动 php-fpm 服务：

/usr/local/bin/php-fpm
本文档未涵盖对 php-fpm 进行进一步配置的信息，如果您需要更多信息，请查阅相关文档。

配置 Nginx 使其支持 PHP 应用：

vim /usr/local/nginx/conf/nginx.conf
修改默认的 location 块，使其支持 .php 文件：

location / {
    root   html;
    index  index.php index.html index.htm;
}
下一步配置来保证对于 .php 文件的请求将被传送到后端的 PHP-FPM 模块， 取消默认的 PHP 配置块的注释，并修改为下面的内容：

location ~* \.php$ {
    fastcgi_index   index.php;
    fastcgi_pass    127.0.0.1:9000;
    include         fastcgi_params;
    fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
    fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
}
重启 Nginx。

sudo /usr/local/nginx/sbin/nginx -s stop
sudo /usr/local/nginx/sbin/nginx
创建测试文件。

rm /usr/local/nginx/html/index.html
echo "<?php phpinfo(); ?>" >> /usr/local/nginx/html/index.php
打开浏览器，访问 http://localhost，将会显示 phpinfo() 。

通过以上步骤的配置，Nginx 服务器现在可以以 SAPI 模块的方式支持 PHP 应用了。 当然，对于 Nginx 和 PHP 的配置，还有很多可用的选项， 请在对应的源代码目录执行 ./configure --help 来查阅更多配置选项。
