Nginx總複習---1

好久沒用Nginx了,估計過段時間公司有些項目需要使用這個,所以決定複習下.今天晚上開始,一晚一篇.隨便說下我是在Debian Squeeze平台下.今天第1篇,從基礎開始,PHP(FastCGI).

1、 在/etc/sysctl.conf文件中加入如下內容,優化

Linux內核參數.

net.ipv4.tcp_max_syn_backlog = 65536

net.core.netdev_max_backlog = 32768

net.core.somaxconn = 32768

net.core.wmem_default = 8388608

net.core.rmem_default = 8388608

net.core.rmem_max = 16777216

net.core.wmem_max = 16777216

net.ipv4.tcp_timestamps = 0

net.ipv4.tcp_synack_retries = 2

net.ipv4.tcp_syn_retries = 2

net.ipv4.tcp_tw_recycle = 1

net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_mem = 94500000 915000000 927000000

net.ipv4.tcp_max_orphans = 3276800

net.ipv4.ip_local_port_range = 1024 65535

2、 使用如下命令使/etc/sysctl.conf文件配置生效.

root@srv76:~# sysctl -p

3、 使用如下命令安裝Nginx.

root@srv76:~# apt-get install nginx

4、 使用如下命令安裝PHP.

root@srv76:~# apt-get install php5-cgi php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-mhash php5-ming php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl spawn-fcgi

5、 在/etc/php5/cgi/php.ini文件中如下內容的註釋取消.

cgi.fix_pathinfo = 1

6、 執行如下命令啟動FastCGI.

/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -u www-data -g www-data -f /usr/bin/php5-cgi -P /var/run/fastcgi-php.pid

7、 將上一句加入/etc/rc.local文件中,使用其每次在開機的時間都會執行.

8、 修改/etc/nginx/nginx.conf文件中如下內容.

user www-data;

worker_processes 10;

error_log /var/log/nginx/error.log crit;

pid /var/run/nginx.pid;

worker_rlimit_nofile 65535;

events {

use epoll;

worker_connections 65535;

}

http {

include /etc/nginx/mime.types;

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

server_names_hash_bucket_size 128;

client_header_buffer_size 32k;

sendfile on;

tcp_nopush on;

keepalive_timeout 50;

tcp_nodelay on;

gzip on;

gzip_min_length 1k;

gzip_buffers 4 16k;

gzip_http_version 1.1;

gzip_comp_level 2;

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

gzip_vary on;

gzip_disable "MSIE [1-6].(?!.*SV1)";

include /etc/nginx/conf.d/*.conf;

include /etc/nginx/sites-enabled/*;

}

9、 在/etc/nginx/sites-enabled/中刪除default

文件並建立名為wiki的文件后如下內容.

server {

listen 80;

server_name _;

access_log /var/log/nginx/localhost.access.log;

location / {

root /web/wiki/;

index index.php index.html index.htm;

}

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root /var/www/;

}

location ~ .php$ {

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME /web/wiki$fastcgi_script_name;

include fastcgi_params;

}

location ~ /.ht {

deny all;

}

}
