| 公司一台2个CPU共8核的服务器访问量上来后top里load高达8到17,但cpu占用却只有Cpu(s): 50%us,可能是static模式下启动php-fpm全起在第一个cpu上了,尝试把nginx的进程指定到第二个cpu上,负载马上降到2左右了: | |
| 有8个核心的话可以把nginx分到第二个cpu的1,3,5,7这4个核上, php5-fpm则默认跑在第一个cpu的0,2,4,6核心, 在nginx.conf里: | |
| worker_processes 4; | |
| worker_cpu_affinity 00000010 00001000 00100000 10000000; #不要用worker_cpu_affinity 10101010; 不均衡 | |
| sudo service nginx restart | |
| 第二个cpu的具体核心序号要先看看核心分布: | |
| grep -P '^physical id' /proc/cpuinfo | |
| 比如4*2核不超线程的可能是:01 01 01 01 也可能是 00 11 00 11, 还可能是10 10 10 10(奇怪的是这些机器不论01先后,0号cpu的负载总是比1号大得多) | |
| 4*2核超线程的可能是:0000 1111 0000 1111 |
| 在top里看到某个php进程占用cpu很高想知道对应的request url: | |
| php 5.3以上有fpm status page功能(http://php.net/manual/en/install.fpm.configuration.php#pm.status-path), 但是从网页访问的, | |
| 改用cgi-fcgi从命令行访问比较安全方便, cgi-fcgi就是cgi(nginx) to fcgi(php5-fpm)的意思 | |
| sudo vi /etc/php5/fpm/pool.d/www.conf | |
| #解除注释 pm.status_path = /status | |
| sudo service php5-fpm restart | |
| sudo apt-get install libfcgi0ldbl #centos是yum install fcgi (先sudo rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm 及 sudo yum upgrade ca-certificates --disablerepo=epel) | |
| sudo SCRIPT_FILENAME=. SCRIPT_NAME=/status QUERY_STRING="full" REQUEST_METHOD=GET cgi-fcgi -bind -connect /var/run/php5-fpm.sock | grep -A7 <pid> |
