12.21 php-fpm的pool
为了避免因多站点使用同一个pool时因一个站点故障导致pool出问题，进而影响使用同一个pool的其他站点的正常运行，要对每个站点配置一个单独的pool。
为php-fpm增加pool

原因是我以为名字不对，后来换了名字还是不行，仔细看配置文件发现原因

为站点配置pool
1[root@cham002 etc]# cd /usr/local/nginx/conf/vhost/ 2[root@cham002 vhost]# ls 3aaa.com.conf load.conf proxy.conf ssl.conf test.com.conf 4[root@cham002 vhost]# vim aaa.com.conf 5 6server 7{ 8 listen 80 default_server; 9 server_name aaa.com; 10 index index.html index.htm index.php; 11 root /data/wwwroot/default; 12 location ~ \.php$ 13 { 14 include fastcgi_params; 15 fastcgi_pass unix:/tmp/champ.sock; 16 #fastcgi_pass 127.0.0.1:9000; 17 fastcgi_index index.php; 18 fastcgi_param SCRIPT_FILENAME /data/wwwroot/default$fastcgi_script_name; 19 } 20 21} 22 23说明： 把fastcgi_pass地址改为和php-fpm.conf中一样的地址就可以。
添加php-fpm.conf子配置文件
为了便于管理，可以将php-fpm中的每个pool单独进行管理。进行如下操作，添加php-fpm子配置文件：
1[root@cham002 vhost]# cd /usr/local/php-fpm/etc/ 2[root@cham002 etc]# vim php-fpm.conf 3[global] 4pid = /usr/local/php-fpm/var/run/php-fpm.pid 5error_log = /usr/local/php-fpm/var/log/php-fpm.log 6include = etc/php-fpm.d/*.conf
说明： 在全局变量版块添加参数“include = etc/php-fpm.d/*.conf”。然后可以清除php-fpm配置文件中其他参数，再到php-fpm.d目录下进行单独设置。
1[root@cham002 vhost]# cd /usr/local/php-fpm/etc/ 2[root@cham002 etc]# mkdir php-fpm.d 3[root@cham002 etc]# cd php-fpm.d/ 4[root@cham002 php-fpm.d]# vim www.conf 5[www] 6listen = /tmp/php-fcgi.sock 7#listen = 127.0.0.1:9000 8listen.mode = 666 9user = php-fpm 10group = php-fpm 11pm = dynamic 12pm.max_children = 50 13pm.start_servers = 20 14pm.min_spare_servers = 5 15pm.max_spare_servers = 35 16pm.max_requests = 500 17rlimit_files = 1024 18[root@cham002 php-fpm.d]# ls 19www.conf 20 21[root@cham002 php-fpm.d]# vim champ.conf 22[champ] 23listen = /tmp/champ.sock 24#listen = 127.0.0.1:9000 25listen.mode = 666 26user = php-fpm 27group = php-fpm 28pm = dynamic 29pm.max_children = 50 30pm.start_servers = 20 31pm.min_spare_servers = 5 32pm.max_spare_servers = 35 33pm.max_requests = 500 34rlimit_files = 1024 35[root@cham002 php-fpm.d]# ls 36champ.conf www.conf 37 38 39[root@cham002 php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t 40[09-Jan-2018 01:20:26] NOTICE: configuration file /usr/local/php-fpm/etc/php-fpm.conf test is successful 41 42[root@cham002 php-fpm.d]# /etc/init.d/php-fpm restart 43Gracefully shutting down php-fpm . done 44Starting php-fpm done 45 46 47[root@cham002 php-fpm.d]# ps aux |grep php-fpm 48root 6508 1.5 0.4 227240 4988 ?

12.23 php-fpm中指定open_basedir
当一台服务器跑多个站点时，使用open_basedir限定各个站点所能访问的服务器上的目录的范围。在php-fpm服务中，可以针对每个pool设定open _ basedir。
