LNMP之 nginx 启动脚本和配置文件

3242423

因为 nginx 启动不方便，所以我们需要自已手动来编译一个nginx 的启动脚本

[iyunv@LNMP ~]# vim /etc/init.d/nginx  #加入以下内容
#!/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

保存后，更改权限:
[iyunv@LNMP ~]# chmod 755 /etc/init.d/nginx  # 更改权限
[iyunv@LNMP ~]# chkconfig --add nginx        #加入到服务列表
[iyunv@LNMP ~]# chkconfig nginx on           #开机启动

[iyunv@LNMP ~]# service nginx configtest #检查配置文件有没有问题
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

---------------------------------------------------------------------------

更改 nginx 配置文件
[iyunv@LNMP ~]# cp /usr/local/nginx/conf/nginx.conf  /usr/local/nginx/conf/nginx.conf.bak
[iyunv@LNMP ~]# >/usr/local/nginx/conf/nginx.conf  #清空nginx.conf 里的配置文件
[iyunv@LNMP ~]# vim /usr/local/nginx/conf/nginx.conf  # 写入以下配置
user nobody nobody;

[iyunv@LNMP ~]# /usr/local/nginx/sbin/nginx  -t  # 检查nginx 的编译
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


[iyunv@LNMP ~]# cd /usr/local/nginx/conf/  
[iyunv@LNMP conf]# mkdir vhosts  #创建 vhosts 目录
[iyunv@LNMP conf]# cd vhosts/
[iyunv@LNMP vhosts]# vim default.conf  # 编辑default.conf ，写入以下内容

server
{
    listen 80 default_server;
    server_name localhost;
    index index.html index.htm index.php;
     root /tmp/1233;  #黙认的虚拟主机设置为 空，访问是会是  403 ，如下图
     deny all;
   以下不用的注释或册除
   # 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;
   # }

}
niginx 启动（一定要检查nginx 是否正常启动）


[iyunv@LNMP vhosts]#mkdir /tmp/1223 #创建这个目录

[iyunv@LNMP vhosts]# /usr/local/nginx/sbin/nginx  -t  #编译完检查

[iyunv@LNMP vhosts]# /etc/init.d/nginx reload    #重新加载配置文件
Reloading Nginx:                                           [  OK  ]



以下可以访问黙认主机的的情形反映
[iyunv@LNMP vhosts]# curl localhost

楼主在编写另一个主机的时候，没有实现 502 的状态，不知何故。
以下 test.com 示例文件
server
{
    listen 80;
    server_name test.com;
    index index.html index.htm index.php;
    root /data/www;

    location ~ .php$ {
        include fastcgi_params;
       #fastcgi_pass unix:/tmp/php-fcgi.sock;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME  /data/www$fastcgi_script_name;
    }

}

[iyunv@LNMP vhosts]# vim test.com
[iyunv@LNMP vhosts]# curl -x127.0.0.1:80 test.com
