    四,配置TFTP

       

     1 # default: off
 2 # description: The tftp server serves files using the trivial file transfer 
 3 #    protocol.  The tftp protocol is often used to boot diskless 
 4 #    workstations, download configuration files to network-aware printers, 
 5 #    and to start the installation process for some operating systems.
 6 service tftp
 7 {
 8     socket_type        = dgram
 9     protocol        = udp
10     wait            = yes

12     server            = /usr/sbin/in.tftpd
13     server_args        = -s /var/lib/tftpboot
14     disable            = no
15     per_source        = 11

     1 . /etc/rc.d/init.d/functions
 2 nginx_name="nginx-1.14.0.tar.gz"
 3 Nginx_Dir="nginx-1.14.0"
 4 Nginx_Install_Dir="/application/nginx-1.14.0"
 5 Install_Nginx(){
 6     #跟新源
 7   wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
 8  # 安装依赖包
 9   yum install -y pcre pcre-devel openssl openssl-devel gcc make gcc-c++
10   if [ -f $nginx_name ]
11     then
12       echo 'nginx need have'
13       # t解压文件
14       tar zxf ${nginx_name} && cd ${Nginx_Dir}
15       # 添加僵尸用户
16       useradd nginx -s /sbin/nologin -M -u 664 
17       # 编译安装
18       ./configure --user=nginx --group=nginx --prefix=${Nginx_Install_Dir} --with-http_stub_status_module --with-http_ssl_module
19       [ $(echo $?) -eq 0 ] && make && make install
20       [ $(echo $?) -eq 0 ] && action nginx安装 /bin/true || action nginx安装 /bin/false  
21         #创建软链接
22      ln -s ${Nginx_Install_Dir} /application/nginx
23  fi
24 }
25 Install_Nginx

    配置nginx.conf

    　　/application/nginx-1.14.0/conf/nginx.conf

         netstat -lntup |grep 80

       

     

    六,挂载光盘

    　　cd /application/nginx-1.14.0/html && m *.html mkdir -p /application/nginx-1.14.0/html/iso/

       mount /dev/cdrom /application/nginx-1.14.0/html/iso/

        

    七,配置支持PXE的启动程序

          yum -y install syslinux

    　　cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/

           cp -a /application/nginx-1.14.0/html/isolinux/* /var/lib/tftpboot/

    　　

    八,尝试启动

    　　

    　 显示这个为正确
