php-fpm的pool（连接池）
我们查看php的进程时，会发现，在最后一个pool的选项，而这个就是我们在php-fpm配置文件里写的一个连接池。
[root@bogon linux.com]# vim /usr/local/php-fpm/etc/php-fpm.conf
[root@bogon linux.com]#
[root@bogon linux.com]# ps aux|grep php
root 3068 0.0 0.0 227144 228 ? Ss 2月11 0:10 php-fpm: master process (/usr/local/php-fpm/etc/php-fpm.conf)
php-fpm 3114 0.0 0.0 229228 124 ? S 2月11 0:00 php-fpm: pool www
1.编辑php-fpm配置文件添加新pool命名为linux.com
[linux.com] listen = /tmp/linux.sock #listen = 127.0.0.1:9000 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
2.检查php配置文件，重新加载配置文件，查看php进程发现有连个pool了
为什么要建立多个池子呢？拿www和linux.com两个池子来说，www池子最多可以同时开50个进程，当www进程满了就会报502错误，这个时候linux.com不受影响。
[root@bogon linux.com]# /usr/local/php-fpm/sbin/php-fpm -t [13-Feb-2018 10:28:14] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful [root@bogon linux.com]# /etc/init.d/php-fpm reload Reload service php-fpm done [root@bogon linux.com]# ps -aux|grep php-fpm
php-fpm 18117 0.0 0.5 229228 5076 ? S 10:29 0:00 php-fpm: pool www php-fpm 18118 0.0 0.5 229228 5076 ? S 10:29 0:00 php-fpm: pool www php-fpm 18119 0.0 0.5 229228 5076 ? S 10:29 0:00 php-fpm: pool www php-fpm 18120 0.0 0.5 229228 5072 ? S 10:29 0:00 php-fpm: pool linux.com php-fpm 18121 0.0 0.5 229228 5076 ? S 10:29 0:00 php-fpm: pool linux.com php-fpm 18122 0.0 0.5 229228 5076 ? S 10:29 0:00 php-fpm: pool linux.com
3.新建pool，编辑aaa.com.conf配置文件添加支持php配置
[root@bogon vhost]# ls aaa.com.conf load.conf proxy.conf ssl.conf test.com.conf [root@bogon vhost]# vim aaa.com.conf [root@bogon vhost]#
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/linux.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /data/wwwroot/default$fastcgi_script_name;
}
}
4.查看nginx配置文件可以看到有个include选项，php-fpm也是支持的
[root@bogon conf]# vim nginx.conf [root@bogon conf]#
gzip_types text/plain application/x-javascript text/css text/htm
application/xml;
include vhost/*.conf;
}
5.编辑php-fpm.conf，在global标签下添加include选项
[root@bogon conf]# vim /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
include = etc/php-fpm.d/*.conf
6.将www配置和linux.com配置拆分开，在etc目录下创建php-fpm.d目录并创建两个配置文件www.conf和linux.conf，在配置文件中分别将拆分出来的配置写到里面
[root@bogon conf]# cd / [root@bogon /]# cd usr/local/php-fpm/etc/ [root@bogon etc]# ls pear.conf php-fpm.conf php-fpm.conf.default php.ini [root@bogon etc]# mkdir php-fpm.d [root@bogon etc]# cd php-fpm.d/ [root@bogon php-fpm.d]# vi www.conf [root@bogon php-fpm.d]#
[www] listen = /tmp/php-fcgi.sock #listen = 127.0.0.1:9000 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@bogon php-fpm.d]# vi linux.conf
[linux.com] listen = /tmp/linux.sock #listen = 127.0.0.1:9000 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
7.删除php-fpm.conf配置文件中的www和linux.com配置
8.检查配置，重启php-fpm everyone ok
[root@bogon php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t [13-Feb-2018 11:39:14] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful [root@bogon php-fpm.d]# /etc/init.d/php-fpm restart Gracefully shutting down php-fpm . done Starting php-fpm done [root@bogon php-fpm.d]#
9.检查服务是否启动，发现一切ok
[root@bogon php-fpm.d]# ps -aux|grep php-fpm root 23264 1.8 0.4 227232 4984 ? Ss 11:39 0:01 php-fpm: master process (/usr/local/php-fpm/etc/php-fpm.conf) php-fpm 23284 0.1 0.5 229256 5080 ? S 11:40 0:00 php-fpm: pool linux.com php-fpm 23285 0.0 0.5 229256 5080 ? S 11:40 0:00 php-fpm: pool linux.com php-fpm 23286 0.0 0.5 229256 5076 ? S 11:40 0:00 php-fpm: pool www php-fpm 23287 0.0 0.5 229256 5076 ? S 11:40 0:00 php-fpm: pool www
