一、Nginx除了bin目录下默认的启动方式和设置变量启动服务之外，我们也可以自己编写启动脚本放置在init.d目录下，让其开机自启服务！
1：编写启动脚本
[root@ghs ~]#
vim /etc/init.d/nginx
将下面的加入到配置文件
#!/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 $RETVAL
2：设置权限
[root@ghs ~]#
chmod 755 /etc/init.d/nginx
3：加入系统服务，并开机自动启动服务
[root@ghs ~]#
chkconfig --add nginx
[root@ghs ~]#
chkconfig nginx on
5：测试启动脚本是否能启动
[root@ghs ~]#
service nginx start
正在启动 Nginx：
[确定]
二、通常情况下，服务器上Nginx服务，都会同时跑一个或者N+个网站，这时候需要我们运维人员自定义编写conf文件，Nginx默认配置文件是没有开启虚拟主机配置，加入include指定虚拟主机conf文件存放路径，开启虚拟主机！
1：编写conf文件
[root@ghs ~]#
vim /usr/local/nginx/conf/nginx.conf
user nobody nobody;
worker_processes 2;
error_log /usr/local/nginx/logs/nginx_error.log crit;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 51200;
events
{
use epoll;
worker_connections 6000;
}
http
{
include mime.types;
default_type application/octet-stream;
server_names_hash_bucket_size 3526;
server_names_hash_max_size 4096;
log_format combined_realip '$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;
}
2：切换目录
[root@ghs nginx]#
cd /usr/local/nginx/conf/
3：创建虚拟主机目录vhosts
[root@ghs conf]#
mkdir vhosts
4：编写配置虚拟主机文件
[root@ghs vhosts]#
vim /vhosts/default.conf
server
{
listen 80 default_server;
server_name localhost;
index index.html index.htm index.php;
root
/tmp/123;这个是不存在的实验用的
}
5：创建WEB服务目录
[root@ghs vhosts]#
cd /tmp/
[root@ghs tmp]#
mkdir 123
6：命令加-t参数，检查虚拟主机配置是否有误
[root@ghs vhosts]#
nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
7：重新加载服务
[root@ghs vhosts]#
nginx -s reload
8：curl命令测试
[root@ghs vhosts]#
curl localhost
<html>
<head><title>404 Not Found</title></head>
<body bgcolor="white">
<center><h1>404 Not Found</h1></center>
