nginx启动脚本和配置文件

1、编写Nginx启动脚本，并加入系统服务
vim /etc/init.d/nginx
并在其中写入如下内容：
#!/bin/bash
# chkconfig: - 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings
NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"
start() {
echo -n $"Starting $prog: "
mkdir -p /dev/shm/nginx_temp
daemon $NGINX_SBIN -c $NGINX_CONF
RETVAL=$?
echo
return $RETVAL
}
stop() {
echo -n $"Stopping $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -TERM
rm -rf /dev/shm/nginx_temp
RETVAL=$?
echo
return $RETVAL
}
reload(){
echo -n $"Reloading $prog: "
killproc -p $NGINX_PID $NGINX_SBIN -HUP
RETVAL=$?
echo
return $RETVAL
}
restart(){
stop
start
}
configtest(){
$NGINX_SBIN -c $NGINX_CONF -t
return 0
}
case "$1" in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
restart
;;
configtest)
configtest
;;
*)
echo $"Usage: $0 {start|stop|reload|

restart|configtest}"
RETVAL=1
esac
exit $RETVAL
并更改文件的执行权限：chmod 755 /etc/init.d/nginx
加入系统服务启动列表：chkconfig --add nginx
并使开机启动：chkconfig nginx on
开启服务： service nginx start
2、更改nginx配置文件
重定向配置文件：>/usr/local/nginx/conf/nginx.conf
可写入如下脚本：
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;
include vhosts/*.conf;
}
在其中加上include vhosts/*.conf
调用vhosts目录下的配置文件。
3、在vhosts目录下创建默认虚拟主机配置文件
禁止任何人访问。
如：vim vhosts/default.conf
server
{
listen 80 default;
server_name localhost;
index index.html index.htm index.php;
root /tmp/111;
deny all;
}
4、在vhosts目录下创建虚拟主机配置文件dd.conf
如：vim vhosts/dd.conf
写入如下内容：
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;
}
}
其中重点有三处：
（1） root /usr/local/nginx/html;
（2）fastcgi_pass unix:/tmp/php-fcgi.sock;
（3）fastcgi_param SCRIPT_FILENAME

/usr/local/nginx/html$fastcgi_script_name;
（1）（3）相同，是指定浏览目录，
（2）指定php-fpm的路径。
