[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]# 可以把test.com.conf定义成fastcgi_pass unix:/tmp/php-fcgi.sock; 这是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$fastcgi_script_name; } access_log /tmp/test.com.log combined_realip; } 再把另一个aaa.com.conf中 fastcgi_pass unix:/tmp/hanfeng.sock; 这是hanfeng.com池子中的hanfeng.sock 路径/data/wwwroot/default$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 这样这两个站点就隔离开了 假设现在test.com请求量很大,最终将进程耗尽了,比如php-fpm耗尽了,这时候又有其他请求来了,就会报502,因为没有多余的php给进程提供服务了,而另一个站点则不受影响,因为使用的是另一个池子,另一个pool,这就是定义多个池子的原因 方法二 在vhost目录下是多个.conf文件,在nginx.conf里面加了一条 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]# 在php-fpm同样是支持 include vhost/*.conf; 在主配置文件php-fpm中的 [global] 加入include = etc/php-fpm.d/*.conf ,并将池子拆分出来,将其中的池子pool删除 快速删除内容方法,100dd就会给删除

[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]#

最终如下

[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 因为include = etc/php-fpm.d/,所以需要创建/php-fpm.d/的目录

[root@hanfeng etc]# mkdir php-fpm.d [root@hanfeng etc]# 切换路径,并创建www.conf,然后将之前php-fpm.conf中的www部分写入到其中

[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 然后在创建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 这样看着就会很干净,类似于nginx的vhost 检查是否有错误

php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/

- 如果路径出错,就会无法正常访问,导致404页面 curl直接连会提示“No input file specified.” 针对www的pool进行配置 在最后一行加入配置
