mini-httpd移植到ARM Linux及如何支持https

news 2025/6/25 6:50:09

mini-httpd是拿来干嘛的？
可以用于嵌入式Linux终端设备的http服务器，以跟cgi交互，可以部署网页访问终端。

下载：
mini_httpd-1.30.tar.gz

解压命令：

tar -xvf mini_httpd-1.30.tar.gz

移植：mini-httpd并没有使用类似其他开源代码那样使用configure，
因为他的移植编译需要我们修改他的Makefile文件；

cat Makefile 
# Makefile for mini_httpd# CONFIGURE: If you are using a SystemV-based operating system, such as
# Solaris, you will need to uncomment this definition.
#SYSV_LIBS =    -lnsl -lsocket# CONFIGURE: Some systems don't need -lcrypt, and indeed they get an
# error if you try to link with it.  If you get an error about libcrypt
# not found, try commenting out this definition.
CRYPT_LIB =    -lcrypt# CONFIGURE: If you want to compile in support for https, uncomment these
# definitions.  You will need to have already built OpenSSL, available at
# http://www.openssl.org/  Make sure the SSL_TREE definition points to the
# tree with your OpenSSL installation - depending on how you installed it,
# it may be in /usr/local instead of /usr/local/ssl.
#SSL_TREE =	/usr/local/ssl
#SSL_DEFS =	-DUSE_SSL
#SSL_INC =	-I$(SSL_TREE)/include
#SSL_LIBS =	-L$(SSL_TREE)/lib -lssl -lcryptoBINDIR =	/usr/local/sbin
MANDIR =	/usr/local/man
CC =		cc

如上；mini-httpd的Makefile很简单；

把makefile改成如下：

CURRENT_DIR := $(CURDIR)
BINDIR =    $(CURRENT_DIR)/usr/sbin
MANDIR =    $(CURRENT_DIR)/usr/man
CC =        arm-nuvoton-linux-gnueabi-gcc

arm-nuvoton-linux-gnueabi-gcc是我的交叉工具链，需要提前设置一下环境变量或者你直接复制全路径
执行如下命令：

make allmake install
root@ubuntu:~/share/gateway/app/openlib/mini_httpd-1.30/usr# ls
man  sbin
root@ubuntu:~/share/gateway/app/openlib/mini_httpd-1.30/usr# tree
.
├── man
│   ├── man1
│   │   └── htpasswd.1
│   └── man8
│       └── mini_httpd.8
└── sbin├── htpasswd└── mini_httpd

为什么改成当前目录下创建usr目录下生成bin文件：因为方便拷贝到开发板及版本制作目录

root@ubuntu:~/share/gateway/app/openlib/mini_httpd-1.30# scp -r ../mini_httpd-1.30/usr/* root@192.168.2.99:/usr/
root@192.168.2.99's password:

root@ubuntu:~/share/gateway/app/openlib/mini_httpd-1.30# 

网页目录：
mkdir www
cgi的bin文件目录：

cd www
mkdir cgi-bin

配置：
vi /etc/mini-httpd.conf 

编辑mini-httpd配置文件mini-httpd.conf ，先仅支持http（文章后面讲https）

# Example config for mini_httpd.# Uncomment this line for turning on ssl support.
#ssl# On which host mini_httpd should bind?
host=0.0.0.0# On which port mini_httpd should listen?
#port=443
port=80
# Which user mini_httpd should use?
user=root# Run in chroot mode?
#chroot # yes
#nochroot # no# Working directory of mini_httpd.
#dir=<work_dir># We are the web files stored?
data_dir=/root/www/# Which certificate to use?
#certfile=/etc/mini_httpd.pem# Which logfile to use?
logfile=/var/log/mini-httpd.log# Which pidfile to use?
pidfile=/var/run/mini-httpd.pid# Which charset to use?
charset=UTF-8cgipat=cgi-bin/*

运行：

/usr/sbin/mini_httpd -C /etc/mini-httpd.conf &

电脑访问：

http://终端ip 

即可访问

重头戏来了，很多客户有加密链接的需求，即https访问；

如何支持https

makefile 修改

SSL_TREE =    /root/share/nuvoton_cross/host/usr/arm-nuvoton-linux-gnueabi/sysroot
SSL_DEFS =    -DUSE_SSL
SSL_INC =    -I$(SSL_TREE)/include
SSL_LIBS =    -L$(SSL_TREE)/lib -lssl -lcrypto
make clean
make all
make install

编译ok

生成证书

make cert

将
scp -r ../mini_httpd-1.30/usr/* root@192.168.2.99:/usr/
cp ../mini_httpd-1.30/usr/* /root/share/nuvoton-build-rootfs/buildroot_out/202401012033/rootfs/usr/ -rf

将mini_httpd.pem拷贝到开发板的/etc/打开https的话  将开发板的mini_httpd的配置文件/etc/mini-httpd.conf编辑如下：

# Example config for mini_httpd.# Uncomment this line for turning on ssl support.
ssl# On which host mini_httpd should bind?
host=0.0.0.0# On which port mini_httpd should listen?
port=443
#port=80
# Which user mini_httpd should use?
user=root# Run in chroot mode?
#chroot # yes
#nochroot # no# Working directory of mini_httpd.
#dir=<work_dir># We are the web files stored?
data_dir=/root/www/# Which certificate to use?
certfile=/etc/mini_httpd.pem# Which logfile to use?
logfile=/var/log/mini-httpd.log# Which pidfile to use?
pidfile=/var/run/mini-httpd.pid# Which charset to use?
charset=UTF-8cgipat=cgi-bin/*

=========================================
该配置文件与http的区别3个地方：
（1）ssl的注释打开
（2）port=443 而http的一般为port=80
（3）certfile=/etc/mini_httpd.pem  //指定证书的位置


把开发板的文件放到以后打包版本的地方
scp /etc/mini-httpd.conf root@192.168.2.240:/root/share/nuvoton-build-rootfs/buildroot_out/202401012033/rootfs/etc/

cp ../mini_httpd-1.30/mini_httpd.pem /root/share/nuvoton-build-rootfs/buildroot_out/202401012033/rootfs/etc/mini_httpd.pem -rf
