php-fpm的pool

  1. php-fpm有一個概念，叫作pool。 使用ps aux |grep php-fpm最右側看到的那一列就是pool，也就是它的池子
[root@hanfeng ~]# ps aux |grep php-fpm
root      2280  0.0  0.4 227776  4952 ?        Ss   18:29   0:00 php-fpm: master process (/usr/local/php-fpm/etc/php-fpm.conf)
php-fpm   2281  0.0  0.4 227776  4708 ?        S    18:29   0:00 php-fpm: pool www

[root@hanfeng ~]#
  1. 切換目錄，會看到咱們只定義了一個www的pool
[root@hanfeng ~]# cd /usr/local/php-fpm/etc/
[root@hanfeng etc]# ls
pear.conf  php-fpm.conf  php-fpm.conf.default  php.ini
[root@hanfeng etc]# cat php-fpm.conf

[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
[root@hanfeng etc]#
  1. 實際上是支持定義多個池子的，每個池子均可以監聽不一樣的sock或者TCP/IP，nginx若是有多個站點，那麼每一個站點都能去使用一個獨立的pool，這樣作的優點就是，當其中一個php發生502了（502頗有多是資源不夠了），若是全部的網站使用了同一個池子，那其中一個網站發生了故障（好比寫的程序有問題），那麼就會把你的php資源耗盡，這樣就會形成其餘的站點也會502，因此有必要把每個站點隔離開來，每個站點使用獨立的pool
  2. 設置多個pool，方法一
  • 在/usr/local/php-fpm/etc/php-fpm裏面，繼續增長pool
    • 寫第二個pool，名稱爲hanfeng.com，listen = /tmp/hanfeng.sock
    • 配置中的其餘信息可根據本身的需求來配置
[root@hanfeng etc]# vi /usr/local/php-fpm/etc/php-fpm.conf

[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024

[hanfeng.com]
listen = /tmp/hanfeng.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024

保存退出
  1. 檢查是否存在語法錯誤
[root@hanfeng etc]# /usr/local/php-fpm/sbin/php-fpm -t
[09-Jan-2018 23:28:58] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful
[root@hanfeng etc]#
  1. 若沒有語法錯誤，作一個php-fpm重啓
    • /etc/init.d/php-fpm restart 或使用 /etc/init.d/php-fpm reload
[root@hanfeng etc]# /etc/init.d/php-fpm reload
Reload service php-fpm  done
[root@hanfeng etc]#
  1. 這裏再來ps查看，會看到最右側多了一個hanfeng.com，這個就是兩個不一樣的池子
[root@hanfeng etc]# ps aux |grep php-fpm

[root@hanfeng etc]#
  1. 在nginx中使用新的pool
[root@hanfeng etc]# cd /usr/local/nginx/conf/vhost/
[root@hanfeng vhost]# ls
aaa.com.conf  load.conf  proxy.conf  ssl.conf  test.com.conf
[root@hanfeng vhost]#
  1. 能夠把test.com.conf定義成fastcgi_pass unix:/tmp/php-fcgi.sock;
    • 這是www池子中的php-fcgi.sock
[root@hanfeng vhost]# vim test.com.conf

server
{
    listen 80;
    server_name test.com test1.com test2.com;
    index index.html index.htm index.php;
    root /data/wwwroot/test.com;
     if ($host != 'test.com' ) {
        rewrite  ^/(.*)$  http://test.com/$1  permanent;
    }
   # location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
   # {
    #      expires      7d;
    #      access_log off;
    #}
location ~* ^.+.(gif|jpg|png|swf|flv|rar|zip|doc|pdf|gz|bz2|jpeg|bmp|xls)$
{
    expires 7d; 
    valid_referers none blocked server_names  *.test.com ;  
    if ($invalid_referer) {                                      

        return 403;                                                  
    }
    access_log off;
}
location ~ .*\.(js|css)$
    {
          expires      12h;
          access_log off;
    }
    location /admin/
    {
    allow 192.168.202.130;
    allow 127.0.0.1;
    deny all;
    }
location ~ \.php$
    {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/php-fcgi.sock; 
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/wwwroot/test.com$fastcgi_script_name;
    }
    access_log /tmp/test.com.log combined_realip; 
}
  1. 再把另外一個aaa.com.conf中 fastcgi_pass unix:/tmp/hanfeng.sock;
    • 這是hanfeng.com池子中的hanfeng.sock
    • 路徑/data/wwwroot/default$fastcgi_script_name;
[root@hanfeng vhost]# vim aaa.com.conf

server
{
    listen 80 default_server;
    server_name aaa.com;
    index index.html index.htm index.php;
    root /data/wwwroot/default;
}
location ~ \.php$
    {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/hanfeng.sock;  
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/wwwroot/default$fastcgi_script_name;
    }
保存退出
  1. 這樣這兩個站點就隔離開了
  2. 假設如今test.com請求量很大，最終將進程耗盡了，好比php-fpm耗盡了，這時候又有其餘請求來了，就會報502，由於沒有多餘的php給進程提供服務了，而另外一個站點則不受影響，由於使用的是另外一個池子，另外一個pool，這就是定義多個池子的緣由

方法二

  1. 在vhost目錄下是多個.conf文件，在nginx.conf裏面加了一條 include vhost/*.conf;
[root@hanfeng vhost]# ls
aaa.com.conf  load.conf  proxy.conf  ssl.conf  test.com.conf
[root@hanfeng vhost]# tail ../nginx.conf
    tcp_nodelay on;
    gzip on;
    gzip_min_length 1k;
    gzip_buffers 4 8k;
    gzip_comp_level 5;
    gzip_http_version 1.1;
    gzip_types text/plain application/x-javascript text/css text/htm 
    application/xml;
    include vhost/*.conf;
}
[root@hanfeng vhost]#
  1. 在php-fpm一樣是支持 include vhost/*.conf;
  2. 在主配置文件php-fpm中的 [global] 加入include = etc/php-fpm.d/*.conf ，並將池子拆分出來，將其中的池子pool刪除
    • 快速刪除內容方法，100dd就會給刪除
[root@hanfeng etc]# cat php-fpm.conf

[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024

[hanfeng.com]
listen = /tmp/hanfeng.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024

[root@hanfeng etc]#

最終以下javascript

[root@hanfeng etc]# vim php-fpm.conf

[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
include = etc/php-fpm.d/*.conf
  1. 由於include = etc/php-fpm.d/，因此須要建立/php-fpm.d/的目錄
[root@hanfeng etc]# mkdir php-fpm.d
[root@hanfeng etc]#
  1. 切換路徑，並建立www.conf，而後將以前php-fpm.conf中的www部分寫入到其中
[root@hanfeng etc]# cd !$
cd php-fpm.d
[root@hanfeng php-fpm.d]# vim www.conf

[www]
listen = /tmp/php-fcgi.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
保存退出
  1. 而後在建立hanfeng.conf
[root@hanfeng php-fpm.d]# vim hanfeng.conf

[hanfeng.com]
listen = /tmp/hanfeng.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
保存退出
  1. 這樣看着就會很乾淨，相似於nginx的vhost
  2. 檢查是否有錯誤
[root@hanfeng php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t
[09-Jan-2018 23:28:58] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful

[root@hanfeng php-fpm.d]#
  1. 而後重啓查看
[root@hanfeng php-fpm.d]# /etc/init.d/php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm  done
[root@hanfeng php-fpm.d]# !ps
ps aux |grep php-fpm
