教你如何搭建编译服务器安装加密系统
一.怎么装Ubuntu 16.04?
二.ubuntu降低内核版本
降低内核版本目的是为了安装加密系统软件
可以参考博客:Ubuntu Linux内核版本升级或降级到指定版本（基于ubuntu 18.04示例）
可以参考博客:Ubuntu 切换系统默认启动内核
1.查看内核版本uname -a , 一般都是4.15.0的, 需要降低内核版本到 4.4.0-xx , 下面以4.4.0-21 为例子:
apt-cache search linux| grep 4.4.0-21
2.安装4.4.0-21内核:
sudo apt-get install linux-headers-4.4.0-21-generic linux-image-4.4.0-21-generic linux-image-extra-4.4.0-21-generic
3.修改内核默认启动顺序:
sudo vim /etc/default/grub
GRUB_DEFAULT="1> 3" GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet" GRUB_CMDLINE_LINUX="find_preseed=/preseed.cfg auto noprompt priority=critical locale=en_US"
4.生效配置 , 重启系统即可
sudo update-grub reboot
你可能会碰到的问题:
1.重启后还是原来的内核版本:
此时需要卸载原来的内核, 以便开机默认就是4.4.0-21内核
2.内核降低后, 以太网卡没有, 不能上网:
原因是降低内核后, 缺少以太网卡驱动, 此时可以使用usb转网卡, 安装万能的以太网卡驱动
三.安装亿赛通加密系统:
1.准备安装包: ultrasec_V300R006C05_amd64.deb
安装包在FTP目录:
ftp://soft@192.168.80.2/%E4%BA%BF%E8%B5%9B%E9%80%9A
sudo dpkg -i ultrasec_V300R006C05_amd64.deb
2.安装成功后重启, 执行usec , 初始登录截图如下:
usec
3.根据对应的提示 1.登录 2.设置服务地址:
服务器地址: 192.168.80.2 端口:8020
4.出现下面的界面表示登录成功了:
5.卸载加密软件方法:
sudo uninstall_ultrasec
四.安装ssh server 和 samba , 添加用户
1.建议更换软件下载源服务器安装速度会快很多, 下面我选择了的是Huawei云, 也可以选择阿里云
sudo apt-get update sudo apt-get ugrade sudo apt-get install samba sudo apt-get install openssh-server
2.将机械硬盘挂载在/home2 目录下:
可以参考博客:ubuntu挂载新硬盘的方法
可以参考博客:Ubuntu 配置磁盘挂载到指定目录
#查看磁盘空间占用情况,从大小上区分可知/dev/sdb1是机械硬盘设备 df -h #查看/dev/sdb1的UUID sudo blkid /dev/sda2 #格式化硬盘格式为ext4 sudo mkfs ext4 /dev/sdb1 #设置自动挂载 sudo vim /etc/fstab 最后加上 UUID=04d4935a-82bb-49b3-99ee-ef576ce6db60 /home2 ext4 defaults 0 2 #重新挂载 sudo mount -a
3.设置下usec的工作区, 增加/home2
4.最后使用下面的脚本, 根据提示可创建用户和对应的samba目录, 非常的方便
#!/bin/bash
GROUP_NAME=tozed
SMBFILE=/etc/samba/smb.conf
enable_samba()
{
homedir=$2
echo "[$1]" >> $SMBFILE
echo -e "\tcomment = smbshare home directory" >> $SMBFILE
echo -e "\tpath = /$homedir/$1" >> $SMBFILE
echo -e "\tbrowseable = yes" >> $SMBFILE
echo -e "\tpublic = yes" >> $SMBFILE

echo -e "\tvalid users = $1" >> $SMBFILE
echo -e "\tforce user = $1" >> $SMBFILE
echo -e "\tforce group = $GROUP_NAME" >> $SMBFILE
echo -e "\tavailable = yes" >> $SMBFILE
echo -e "\tunix charset = UTF-8" >> $SMBFILE
echo -e "\tdos charset = cp936" >> $SMBFILE
echo "" >> $SMBFILE
sudo smbpasswd -a $1
sudo systemctl restart smbd.service
}
delete_samba()
{
echo "===>Start to delete samba config..."
sudo sed -i "/^\[$1\]/,/^\[/{//!d}" $SMBFILE
sudo sed -i "/^\[$1\]/d" $SMBFILE
echo "===>Start to delete samba passwd..."
sudo smbpasswd -x $1
echo "===>Start to restart samba service..."
sudo systemctl restart smbd.service
}
change_samba_passwd()
{
sudo smbpasswd $1
sudo systemctl restart smbd.service
}
add_user()
{
egrep "^$GROUP_NAME" /etc/group >& /dev/null
if [ $? -ne 0 ]; then
sudo groupadd $GROUP_NAME
fi
id $1 >& /dev/null
if [ $? -ne 0 ]; then
# sudo useradd -g $GROUP_NAME -m $1

sudo chmod 755 /$HOME_NAME/$1
