KICKSTART无人值守安装

一, 安装DHCP

　　yum -y install dhcp

二, 配置dhcp

     

　　

#
# DHCP Server Configuration file.
#   see /usr/share/doc/dhcp*/dhcpd.conf.sample
#   see 'man 5 dhcpd.conf'

subnet 10.0.0.0 netmask 255.255.255.0 {

        range 10.0.0.206 10.0.0.240;

        option subnet-mask 255.255.255.0;

        default-lease-time 21600;

        max-lease-time 43200;

        next-server 10.0.0.70;

        filename "/pxelinux.0";

}

　　启动 dhcp 

      /etc/init.d/dhcpd start

     

三,安装tftp

    yum -y install tftp-server

四,配置TFTP

  

# default: off
# description: The tftp server serves files using the trivial file transfer 
#    protocol.  The tftp protocol is often used to boot diskless 
#    workstations, download configuration files to network-aware printers, 
#    and to start the installation process for some operating systems.
service tftp
{
    socket_type        = dgram
    protocol        = udp
    wait            = yes
    user            = root
    server            = /usr/sbin/in.tftpd
    server_args        = -s /var/lib/tftpboot
    disable            = no
    per_source        = 11
    cps            = 100 2
    flags            = IPv4
}

   启动xinetd.d

  /etc/init.d/xinetd

 

五, 安装http服务

     nginx安装

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

配置nginx.conf

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

worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        location / {
            autoindex on;
            root   html;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

启动服务

 　　/application/nginx/sbin/nginx

　　

     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

九,配置自动安装

   

 mkdir /application/nginx-1.14.0/html/ks_config -p

cat /application/nginx-1.14.0/html/ks_config/CentOS-6.9-ks.cfg
