前面我已經寫了debian下如何快速部署nginx,這裡我再說下nginx如何支援php網站,适合新手。
1、首先修改nginx的配置檔案(标色的為我修改過或添加過的内容)
vim /etc/nginx/conf/nginx.conf
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
worker_rlimit_nofile 51200; //需要在shell下執行ulimit -SHn 512 00
events {
use epoll;
worker_connections 51200;
}
http {
include mime.types;
default_type application/octet-stream;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
log_format access '$remote_addr - $remote_user [$time_local] "$request" '
'"$status" $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log access;
sendfile on;
tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 60;
tcp_nodelay on;
#gzip on;
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root /home/web;
index index.php index.html index.htm;
if (-f $request_filename/index.html){
rewrite (.*) $1/index.html break;
}
if (-f $request_filename/index.php){
rewrite (.*) $1/index.php;
}
if (-f $request_filename){
rewrite (.*) /index.php;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#location ~ \.php$ {
# proxy_pass [url]http://127.0.0.1[/url];
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /home/web$fastcgi_script_name; //home/web 為php網站的目錄
include fastcgi_params;
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#location ~ /\.ht {
# deny all;
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
# listen 443;
# server_name localhost;
# ssl on;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_timeout 5m;
# ssl_protocols SSLv2 SSLv3 TLSv1;
# ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
# ssl_prefer_server_ciphers on;
以上是我的nginx.conf檔案内容
2、安裝php5-cgi子產品
apt-get install php5-cgi php5-gd php5-curl
修改/etc/php5/cgi/php.ini檔案,裡面有一項cgi.fix_pathinfo資料為1,預設為0 cgi.fix_pathinfo=1; 這樣php5-cgi方能正常使用SCRIPT_FILENAME這個變量。
這裡還要裝一個php加速的軟體ZendOptimizer,在輸入php.ini位置的時候輸入
/etc/php5/cgi/
3、安裝spawn-fcgi spawn-fcgi是lighttpd的一個用來控制php-cgi的工具
如果系統沒有安裝GCC編譯環境,剛需要在安裝lighttpd之前要安裝build-essential工具包,執行以下指令
aptitude install build-essential libpcre3-dev
wget [url]http://www.lighttpd.net/download/lighttpd-1.4.19.tar.gz[/url]
tar xzvf lighttpd-1.4.19.tar.gz
cd lighttpd-1.4.19/
./configure –without-zlib –without-bzip2
make
cd src
cp spawn-fcgi /usr/local/bin/spawn-fcgi
這樣cgi控制器就安裝完成了。
4、啟動cgi
spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -u www -g www -f /usr/bin/php5-cgi
注意:ip,端口與nginx伺服器中的fastcgi-pass要對應. -C表示打開幾個cgi程序
啟動nginx ,在啟動之前先測試下配置檔案是否正确
nginx -t -c /etc/nginx/conf/nginx.conf
2009/02/03 15:27:12 [info] 21782#0: the configuration file /etc/nginx/conf/nginx.conf syntax is ok
2009/02/03 15:27:12 [info] 21782#0: the configuration file /etc/nginx/conf/nginx.conf was tested successfully
出現以上資訊說明配置檔案準确。
/etc/init.d/nginx start
好了,如果沒有出錯資訊,則說明配置成功了,現在寫個phpinfo測試下吧
cd /home/web
nano index.php
輸入
<?
phpinfo();
?>
儲存。
測試是否出現phpinfo
lynx [url]http://127.0.0.1/index.php[/url] 或者用其它機器通路本機
完成。
