如何最接近rpm的安装方式去编译安装最新的php-fpm

笔者非常不喜欢某些人编译安装的软件，维护起来非常缺乏rpm安装的那种规范感觉，于是笔者参阅官方的编译安装教程以及对比分析rpm安装的目录布置结构，完成以下安装。

2 安装PHP-FPM

2.1 环境配置

2.1.1 安装解压工具

yum install -y bzip2

2.1.2 配置编译环境

yum -y install gcc gcc-c++ make expat-devel

2.1.3 下载php二进制安装包

cd ~

wget http://cn2.php.net/distributions/php-7.1.12.tar.bz2

注：具体的下载页面请参阅

http://sg2.php.net/downloads.php

2.1.4 创建运行用户

groupadd  -g 48 apache

useradd -u 48 -g 48 -d /usr/share/httpd -s /sbin/nologin apache

2.1.5 预建目录

mkdir /var/log/php-fpm/

mkdir /run/php-fpm/

2.1.6 配置防火墙

firewall-cmd --permanent --add-port 9000/tcp

firewall-cmd --reload

firewall-cmd --list-all

2.2 编译安装

2.2.1 解压安装包

tar -xf php-7.1.12.tar.bz2

2.2.2 安装前构建

cd php-7.1.12       

./configure --bindir=/usr/sbin/ \

            --sbindir=/usr/sbin/ \

            --sysconfdir=/etc/ \

            --libdir=/usr/lib64/  \

            --mandir=/usr/share/man/ \

            --includedir=/usr/include/ \

            --with-fpm-user=apache \

            --with-fpm-group=apache \

            --enable-fpm \

            --with-mysqli

根据提示解决安装的依赖关系

yum install -y libxml2-devel

2.2.3 编译并安装

make

make install | tee install.log

2.3 配置FPM

2.3.1 配置php.ini

cp php.ini-development /etc/php.ini

2.3.2 防止空文件递给PHP-FPM后端

vim /etc/php.ini

修改以下参数：

cgi.fix_pathinfo = 0

注：可防任意脚本注入

2.3.3 创建配置

vim /etc/php-fpm.conf

加入如下配置：

;;;;;;;;;;;;;;;;;;;;;

; FPM Configuration ;

;;;;;;;;;;;;;;;;;;;;;

; All relative paths in this configuration file are relative to PHP's install

; prefix.

; Include one or more files. If glob(3) exists, it is used to include a bunch of

; files from a glob(3) pattern. This directive can be used everywhere in the

; file.

include=/etc/php-fpm.d/*.conf

;;;;;;;;;;;;;;;;;;

; Global Options ;

;;;;;;;;;;;;;;;;;;

[global]

; Pid file

; Default Value: none

pid = /run/php-fpm/php-fpm.pid

; Error log file

; Default Value: /var/log/php-fpm.log

error_log = /var/log/php-fpm/error.log

; 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 '0' means 'Off'.

; Default Value: 0

;emergency_restart_threshold = 0

; 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: 0

;emergency_restart_interval = 0

; 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: 0

;process_control_timeout = 0

; Send FPM to background. Set to 'no' to keep FPM in foreground for debugging.

; Default Value: yes

daemonize = no

;;;;;;;;;;;;;;;;;;;;

; Pool Definitions ;

;;;;;;;;;;;;;;;;;;;;

; See /etc/php-fpm.d/*.conf

创建以下配置文件：

mkdir /etc/php-fpm.d/

vim /etc/php-fpm.d/www.conf

加入如下配置：

; Start a new pool named 'www'.

[www]

; The address on which to accept FastCGI requests.

; Valid syntaxes are:

;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific address on

;                            a specific port;

;   'port'                 - to listen on a TCP socket to all addresses on a

;                            specific port;

;   '/path/to/unix/socket' - to listen on a unix socket.

; Note: This value is mandatory.

listen = 127.0.0.1:9000

; Set listen(2) backlog. A value of '-1' means unlimited.

; Default Value: -1

;listen.backlog = -1

; List of ipv4 addresses of FastCGI clients which are allowed to connect.

; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original

; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address

; must be separated by a comma. If this value is left blank, connections will be

; accepted from any ip address.

; Default Value: any

listen.allowed_clients = 127.0.0.1

; Set permissions for unix socket, if one is used. In Linux, read/write

; permissions must be set in order to allow connections from a web server. Many

; BSD-derived systems allow connections regardless of permissions. 

; Default Values: user and group are set as the running user

;                 mode is set to 0666

;listen.owner = nobody

;listen.group = nobody

;listen.mode = 0666

; Unix user/group of processes

; Note: The user is mandatory. If the group is not set, the default user's group

;       will be used.

; RPM: apache Choosed to be able to access some dir as httpd

user = apache

; RPM: Keep a group allowed to write in log dir.

group = apache

; Choose how the process manager will control the number of child processes.

; Possible Values:

;   static  - a fixed number (pm.max_children) of child processes;

;   dynamic - the number of child processes are set dynamically based on the

;             following directives:

;             pm.max_children      - the maximum number of children that can

;                                    be alive at the same time.

;             pm.start_servers     - the number of children created on startup.

;             pm.min_spare_servers - the minimum number of children in 'idle'

;                                    state (waiting to process). If the number

;                                    of 'idle' processes is less than this

;                                    number then some children will be created.

;             pm.max_spare_servers - the maximum number of children in 'idle'

;                                    state (waiting to process). If the number

;                                    of 'idle' processes is greater than this

;                                    number then some children will be killed.

; Note: This value is mandatory.

pm = dynamic

; The number of child processes to be created when pm is set to 'static' and the

; maximum number of child processes to be created when pm is set to 'dynamic'.

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

; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.

; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP

; CGI.

; Note: Used when pm is set to either 'static' or 'dynamic'

; Note: This value is mandatory.

pm.max_children = 50

; The number of child processes created on startup.

; Note: Used only when pm is set to 'dynamic'

; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2

pm.start_servers = 5

; The desired minimum number of idle server processes.

; Note: Used only when pm is set to 'dynamic'

; Note: Mandatory when pm is set to 'dynamic'

pm.min_spare_servers = 5

; The desired maximum number of idle server processes.

; Note: Used only when pm is set to 'dynamic'

; Note: Mandatory when pm is set to 'dynamic'

pm.max_spare_servers = 35

; The number of requests each child process should execute before respawning.

; This can be useful to work around memory leaks in 3rd party libraries. For

; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.

; Default Value: 0

;pm.max_requests = 500

; The URI to view the FPM status page. If this value is not set, no URI will be

; recognized as a status page. By default, the status page shows the following

; information:

;   accepted conn    - the number of request accepted by the pool;

;   pool             - the name of the pool;

;   process manager  - static or dynamic;

;   idle processes   - the number of idle processes;

;   active processes - the number of active processes;

;   total processes  - the number of idle + active processes.

; The values of 'idle processes', 'active processes' and 'total processes' are

; updated each second. The value of 'accepted conn' is updated in real time.

; Example output:

;   accepted conn:   12073

;   pool:             www

;   process manager:  static

;   idle processes:   35

;   active processes: 65

;   total processes:  100

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

; 'html' or 'json' as a query string will return the corresponding output

; syntax. Example:

;   http://www.foo.bar/status

;   http://www.foo.bar/status?json

;   http://www.foo.bar/status?html

; Note: The value must start with a leading slash (/). The value can be

;       anything, but it may not be a good idea to use the .php extension or it

;       may conflict with a real PHP file.

; Default Value: not set 

;pm.status_path = /status

; The ping URI to call the monitoring page of FPM. If this value is not set, no

; URI will be recognized as a ping page. This could be used to test from outside

; that FPM is alive and responding, or to

; - create a graph of FPM availability (rrd or such);

; - remove a server from a group if it is not responding (load balancing);

; - trigger alerts for the operating team (24/7).

; Note: The value must start with a leading slash (/). The value can be

;       anything, but it may not be a good idea to use the .php extension or it

;       may conflict with a real PHP file.

; Default Value: not set

;ping.path = /ping

; This directive may be used to customize the response of a ping request. The

; response is formatted as text/plain with a 200 response code.

; Default Value: pong

;ping.response = pong

; The timeout for serving a single request after which the worker process will

; be killed. This option should be used when the 'max_execution_time' ini option

; does not stop script execution for some reason. A value of '0' means 'off'.

; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)

; Default Value: 0

;request_terminate_timeout = 0

; The timeout for serving a single request after which a PHP backtrace will be

; dumped to the 'slowlog' file. A value of '0s' means 'off'.

; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)

; Default Value: 0

;request_slowlog_timeout = 0

; The log file for slow requests

; Default Value: not set

; Note: slowlog is mandatory if request_slowlog_timeout is set

slowlog = /var/log/php-fpm/www-slow.log

; Set open file descriptor rlimit.

; Default Value: system defined value

;rlimit_files = 1024

; Set max core size rlimit.

; Possible Values: 'unlimited' or an integer greater or equal to 0

; Default Value: system defined value

;rlimit_core = 0

; Chroot to this directory at the start. This value must be defined as an

; absolute path. When this value is not set, chroot is not used.

; Note: chrooting is a great security feature and should be used whenever 

;       possible. However, all PHP paths will be relative to the chroot

;       (error_log, sessions.save_path, ...).

; Default Value: not set

;chroot = 

; Chdir to this directory at the start. This value must be an absolute path.

; Default Value: current directory or / when chroot

;chdir = /var/www

; Redirect worker stdout and stderr into main error log. If not set, stdout and

; stderr will be redirected to /dev/null according to FastCGI specs.

; Default Value: no

;catch_workers_output = yes

; Limits the extensions of the main script FPM will allow to parse. This can

; prevent configuration mistakes on the web server side. You should only limit

; FPM to .php extensions to prevent malicious users to use other extensions to

; exectute php code.

; Note: set an empty value to allow all extensions.

; Default Value: .php

;security.limit_extensions = .php .php3 .php4 .php5

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from

; the current environment.

; Default Value: clean env

;env[HOSTNAME] = $HOSTNAME

;env[PATH] = /usr/local/bin:/usr/bin:/bin

;env[TMP] = /tmp

;env[TMPDIR] = /tmp

;env[TEMP] = /tmp

; Additional php.ini defines, specific to this pool of workers. These settings

; overwrite the values previously defined in the php.ini. The directives are the

; same as the PHP SAPI:

;   php_value/php_flag             - you can set classic ini defines which can

;                                    be overwritten from PHP call 'ini_set'. 

;   php_admin_value/php_admin_flag - these directives won't be overwritten by

;                                     PHP call 'ini_set'

; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.

; Defining 'extension' will load the corresponding shared extension from

; extension_dir. Defining 'disable_functions' or 'disable_classes' will not

; overwrite previously defined php.ini values, but will append the new value

; instead.

; Default Value: nothing is defined by default except the values in php.ini and

;                specified at startup with the -d argument

;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com

;php_flag[display_errors] = off

php_admin_value[error_log] = /var/log/php-fpm/www-error.log

php_admin_flag[log_errors] = on

;php_admin_value[memory_limit] = 128M

; Set session path to a directory owned by process user

php_value[session.save_handler] = files

php_value[session.save_path] = /var/lib/php/session
