nginx核心優化及配置

1、核心優化

net.ipv4.ip_forward = 0

net.ipv4.conf.default.rp_filter = 1

net.ipv4.conf.default.accept_source_route = 0

kernel.sysrq = 0

kernel.core_uses_pid = 1

kernel.msgmnb = 65536

kernel.msgmax = 65536

kernel.shmmax = 68719476736

kernel.shmall = 4294967296

net.core.rmem_max = 16777216

net.core.wmem_max = 16777216

net.core.netdev_max_backlog = 30000

net.core.somaxconn = 262144

net.ipv4.tcp_rmem = 4096 87380 16777216

net.ipv4.tcp_wmem = 4096 65536 16777216

net.ipv4.tcp_fin_timeout = 1

net.ipv4.tcp_tw_recycle = 1

net.ipv4.tcp_tw_reuse = 0

net.ipv4.tcp_keepalive_time = 30

net.ipv4.tcp_max_tw_buckets = 6000

net.ipv4.tcp_keepalive_probes = 5

net.ipv4.tcp_keepalive_intvl = 15

net.ipv4.tcp_no_metrics_save = 1

net.ipv4.tcp_syncookies = 1

net.ipv4.tcp_max_orphans = 262144

net.ipv4.tcp_max_syn_backlog = 262144

net.ipv4.tcp_synack_retries = 1

net.ipv4.tcp_syn_retries = 1

net.ipv4.ip_conntrack_max = 6553600

net.ipv4.netfilter.ip_conntrack_tcp_timeout_established = 180

net.ipv4.tcp_window_scaling = 1

net.ipv4.ip_local_port_range = 1024    65000

net.ipv4.tcp_timestamps = 0

2、設定檔案描述符

3、nginx優化配置

user  www www;

worker_processes 8;

worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000;

error_log  /usr/local/nginx/logs/error.log  warn;

worker_rlimit_nofile 65536;

events

{

      use epoll;

      worker_connections 65536;

}

http

        include       mime.types;

        default_type  application/octet-stream;

        server_names_hash_bucket_size 128;

        keepalive_timeout 60;

        client_header_buffer_size    4k;   //系統分頁大小#getconf PAGESIZE

        client_max_body_size         32m;

        large_client_header_buffers  8 1024k;

        client_header_timeout  3m;

        client_body_timeout    3m;

        send_timeout           3m;

        connection_pool_size        256;

        request_pool_size        4k;

        output_buffers   16 128k;

        postpone_output  1460;

        fastcgi_connect_timeout 300;

        fastcgi_send_timeout 300;

        fastcgi_read_timeout 300;

        fastcgi_buffer_size 128k;

        fastcgi_buffers 16 256k;

        fastcgi_busy_buffers_size 512k;

        fastcgi_temp_file_write_size 512k;

        fastcgi_temp_path /dev/shm;

        open_file_cache max=65536 inactive=20s;

        open_file_cache_min_uses 1;

        open_file_cache_valid 30s;

        tcp_nodelay on;

        gzip on;

        gzip_static on;

        gzip_proxied        any;

        gzip_disable        "MSIE [1-5]."

        gzip_comp_level     9;

        gzip_min_length  1k;

        gzip_buffers     16 128k;

        gzip_http_version 1.0;

        gzip_types       text/plain application/x-javascript text/css application/xml;

        server_name_in_redirect off;

        log_format  access  '$remote_addr $remote_user - [$time_local] "$request" '

                            '$status $body_bytes_sent "$http_referer" '

                            '"$http_user_agent" $http_x_forwarded_for';

        include /usr/local/nginx/conf/vhost/*.conf;

4、vhost配置

   #vim /usr/local/nginx/conf/vhost/a.conf

   server

   {

    listen 80;

    server_name www.abc.com;

    root /data/httpd/csm.shopex.cn;

    index index.php index.html index.htm;

    location ~ .*\.php?$

    {

            include fastcgi.conf;

            fastcgi_pass  127.0.0.1:9000;

            fastcgi_index index.php;

    }

    #access_log  /var/log/nginx/nginx-access.log access;
