A, Nginx addition to the default startup mode bin directory and set variables to start the service, we can also write your own startup script placed in the init.d directory, let it boot from Kai service!
1: write startup scripts
[root@ghs ~]#
vim /etc/init.d/nginx
The following is added to the configuration file
#!/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

<head><title>404 Not Found</title></head>
<body bgcolor="white">
<center><h1>404 Not Found</h1></center>
