定制微型linux实现启用虚拟终端基于帐号密码登录、提供ssh服务，提供Web服务（下）附有命令移植脚本 推荐

# vim /mnt/sysroot/etc/nsswitch.conf
#
# /etc/nsswitch.conf
#
passwd:     files
shadow:     files
group:      files
#hosts:     db files nisplus nis dns
hosts:      files dns

# vim etc/shells
/bin/bash    上面已经已经移植bash
/bin/sh
/bin/hush
/bin/ash
/bin/

# cd /mnt/sysroot/etc
1.创建运行dropbear服务时所需要的目录
# mkdir rc.d/init.d
# mkdir -pv var/lock/subsys

2.为dropbear提供服务脚本
#!/bin/bash
#
# description: dropbear ssh daemon
# chkconfig: 2345 66 33
#
dsskey=/etc/dropbear/dropbear_dss_host_key
rsakey=/etc/dropbear/dropbear_rsa_host_key

[ -r /etc/sysconfig/dropbear ] && . /etc/sysconfig/dropbear
keysize=${keysize:-1024}
port=${port:-22}
gendsskey() {
[ -d /etc/dropbear ] || mkdir /etc/dropbear
echo -n "Starting generate the dss key: "
$dropbearkey -t dss -f $dsskey &> /dev/null
RETVAL=$?
if [ $RETVAL -eq 0 ]; then
success
echo
return 0
else
failure
echo
return 1
fi
}
genrsakey() {

echo -n "Starting generate the rsa key: "
$dropbearkey -t rsa -s $keysize -f $rsakey &> /dev/null
RETVAL=$?
if [ $RETVAL -eq 0 ]; then
success
echo
return 0
else
failure
echo
return 1
fi
}
start() {
[ -e $dsskey ] || gendsskey
[ -e $rsakey ] || genrsakey
if [ -e $lockfile ]; then
echo -n "dropbear daemon is already running: "
success
echo
exit 0
fi
echo -n "Starting dropbear: "
daemon --pidfile="$pidfile" $dropbear -p $port -d $dsskey -r $rsakey
RETVAL=$?
echo
if [ $RETVAL -eq 0 ]; then
touch $lockfile
return 0
else
rm -f $lockfile $pidfile
return 1
fi
}
stop() {
if [ ! -e $lockfile ]; then
echo -n "dropbear service is stopped: "
success
echo
exit 1

echo -n "Stopping dropbear daemon: "
killproc dropbear
RETVAL=$?
echo

if [ $RETVAL -eq 0 ]; then
rm -f $lockfile $pidfile
return 0
else

}
status() {
if [ -e $lockfile ]; then
echo "dropbear is running..."
else
echo "dropbear is stopped..."

}
usage() {

}

esac
3.给dropbear脚本可执行权限
# chmod +x rc.d/init.d/dropbear

4.复制宿主机中的functions至目标磁盘
# cp /etc/rc.d/init.d/functions rc.d/init.d/

5.创建连接文件以便于开机自动启动，关机自动停止
# cd rc.d/
# ln -sv init.d/dropbear dropbear.start
# ln -sv init.d/dropbear dropbear.stop

6.编辑为目标提供的rc.sysinit，在最后一行添加如下代码，使其开机后自动启动服务
#vim rc.sysinit
/etc/rc.d/*.start start

7.编辑rc.sysdown使其能够关机之前自动关闭服务
# vim rc.sysdown
#!/bin/bash
#
sync
sleep 3
sync
/etc/rc.d/*.stop stop
/bin/umount -a -r
poweroff
8.在inittab中将最后一行改为如下行
# vim ../inittab
::shutdown:/etc/rc.d/rc.sysdown

编译安装Nginx
# groupadd -r nginx
# useradd -r -g nginx -s /bin/nologin  nginx
# tar -xf nginx-1.5.9.tar.gz
# cd nginx-1.5.9
# ./configure
--prefix=/usr/local/nginx
--conf-path=/etc/nginx/nginx.conf
--error-log-path=/var/log/nginx/error.log
--http-log-path=/var/log/nginx/access.log
--pid-path=/var/run/nginx/nginx.pid
--lock-path=/var/lock/nginx.lock
--user=nginx --group=nginx
--group=nginx
--without-http_rewrite_module
--without-pcre --without-http_geo_module
--without-http_uwsgi_module
--without-http_fastcgi_module
--without-http_scgi_module
--without-http_memcached_module

# make && make install

# /usr/local/nginx/sbin/nginx
# ss -ntl | grep ":80"
LISTEN     0      128                       *:80                       *:*

1为Nginx提供属主和属组，使其能正常启动
grep "^nginx" /etc/passwd >> passwd
#grep "^nginx" /etc/group  >> group
# grep "^nginx" /etc/shadow >> shadow
2自定以脚本移植nginx
# bash /study/cpcommand.sh
Enter a available Command OR quit (quit):/usr/local/nginx/sbin/nginx
Copy /usr/local/nginx/sbin/nginx Successful!!!
Copy /lib/libpthread.so.0 Successful!!!
LibFile Exist! .....Enter Again!

LibFile Exist! .....Enter Again!
LibFile Exist! .....Enter Again!
LibFile Exist! .....Enter Again!
LibFile Exist! .....Enter Again!
LibFile Exist! .....Enter Again!
Enter a available Command OR quit (quit):quit
quit  wait 1  second.....

3.将nginx的配置文件移植目标系统
# cp -r /etc/nginx  /mnt/sysroot/etc/

4.为属主机提供web服务的根目录和测试页
mkdir /mnt/sysroot/usr/local/html
# vim /mnt/sysroot/usr/local/index.html
<h1> Tiny Linux </h1>
5.为宿主机提供服务启动脚本
# vim /mnt/sysroot/etc/rc.d/init.d/nginx
#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#

6.给服务脚本提供可执行权限
# chmod +x  /mnt/sysroot/etc/rc.d/init.d/nginx

7.使Nginx能够开机自动启动，关机自动关闭
# cd /mnt/sysroot/etc/rc.d
# ln -sv init.d/nginx  nginx.start
# ln -sv init.d/nginx  nginx.stop

8.创建启动nginx所需要的目录
# mkdir /mnt/sysroot/var/log/nginx
# mkdir /mnt/sysroot/usr/local/logs

nginx已然启动
