LNMP-------nginx、php配置

一. nginx.conf 

vim /usr/local/nginx/conf/nginx.conf //清空原来的配置，加入如下内容：

user nobody nobody;
worker_processes 2;
error_log /usr/local/nginx/logs/nginx_error.log crit;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 51200;
events
{
    use epoll;
    worker_connections 6000;
}
http

{
    include mime.types;
    default_type application/octet-stream;
    server_names_hash_bucket_size 3526;
    server_names_hash_max_size 4096;
    log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]'
    '$host "$request_uri" $status'
    '"$http_referer" "$http_user_agent"';
    sendfile on;
    tcp_nopush on;
    keepalive_timeout 30;
    client_header_timeout 3m;
    client_body_timeout 3m;
    send_timeout 3m;
    connection_pool_size 256;
    client_header_buffer_size 1k;
    large_client_header_buffers 8 4k;
    request_pool_size 4k;
    output_buffers 4 32k;
    postpone_output 1460;
    client_max_body_size 10m;
    client_body_buffer_size 256k;
    client_body_temp_path /usr/local/nginx/client_body_temp;
    proxy_temp_path /usr/local/nginx/proxy_temp;
    fastcgi_temp_path /usr/local/nginx/fastcgi_temp;
    fastcgi_intercept_errors on;
    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;

server

{
    listen 80;
    server_name localhost;
    index index.html index.htm index.php;
    root /usr/local/nginx/html;

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/php-fcgi.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
    }
}
}

二. php-fpm.conf

vim   /usr/local/php/etc/php-fpm.conf     //把之前的内容清空，然后写入如下配置：

[global] 
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log 
[www] 
listen = /tmp/php-fcgi.sock 
user = php-fpm 
group = php-fpm
listen.owner = nobody  //和后面的nginx的一致
listen.group = nobody // 同上
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 

配置多个pool
[global]
...
...
[domain1.com]
...
...
...
[domain2.com]
...
...
...

动态、静态子进程pm = static/dynamic
如果选择static，则由pm.max_children指定固定的子进程数。
如果选择dynamic，则由以下参数决定：
pm.max_children ，子进程最大数
pm.start_servers ，启动时的进程数
pm.min_spare_servers ，保证空闲进程数最小值，如果空闲进程小于此值，则创建新的子进程
pm.max_spare_servers ，保证空闲进程数最大值，如果空闲进程大于此值，此进行清理
对于专用服务器，pm可以设置为static。
