Goahead 编译
目录说明
Makefile #顶层Makefile,可以自动检测当前运行平台的环境,并调用projects的mk
projects #子层的Makefile,有各个平台的
test # web 文件以及路由和配置文件
#可以看到直接make 输出如下
make --no-print-directory -f projects/goahead-linux-default.mk all
# 安装
sudo make install
Ubuntu编译
make
make
sudo make install
selfkey处理
reallin@ubuntu:/work/goahead/goahead-5.0.1$ sudo goahead -v --home /etc/goahead /var/www/goahead
goahead: 0: Unable to read key self.key
goahead: 0: Cannot initialize server. Exiting.
sudo cp ./build/linux-x64-default/bin/self.key /etc/goahead
sudo cp ./build/linux-x64-default/bin/self.crt /etc/goahead
测试
#./goahead -v --home 配置文件路径 文档路径 绑定IP:监听端口
#./goahead -v --home /etc/goahead /var/www/goahead 0.0.0.0:8888
sudo goahead -v --home /etc/goahead /var/www/goahead
# 下面是运行结果
goahead: 2: Configuration for Embedthis GoAhead Community Edition
goahead: 2: ---------------------------------------------
goahead: 2: Version: 5.0.1
goahead: 2: BuildType: Debug
goahead: 2: CPU: x64
goahead: 2: OS: linux
goahead: 2: Host: 127.0.1.1
goahead: 2: Directory: /etc/goahead
goahead: 2: Documents: /var/www/goahead
goahead: 2: Configure: me -d -q -platform linux-x86-default -configure . -gen make
goahead: 2: ---------------------------------------------
goahead: 2: Started http://*:80
goahead: 2: Started https://*:443
具体的install目录
ls /etc/goahead
auth.txt route.txt self.crt self.key
ls /var/www/goahead
favicon.ico index.html # 这个就是网页了
交叉编译
# 如果有错误提示 undefined reference to `__stack_chk_fail' 加上这个选项-fno-stack-protector
make CC=arm-linux-gcc LD=arm-linux-ld CFLAGS=-fno-stack-protector
方便测试
-
cd build/linux-x64-default/bin -
cp ../../../src/auth.txt ./ -
cp ../../../src/route.txt ./ -
新建一个
myweb文件夹存网页 -
sudo ./goahead -v ./myweb/ -
修改配置文件route.txt
1.把route uri=/action handler=action注释掉 在前面加个#即可 然后加一句route uri=/action/ methods=GET|POST handler=action 2. 把route uri=/ extensions=jst handler=jst改为route uri=/ extensions=jst,asp,html handler=jst 如果不做修改那我们在以后写html，asp文件里的action就不能被识别
win下编译
顶层目录的make.bat 修改下,因为原来的默认工程找不到路径
projectswindows x64 nmake -f projects/goahead-windows-default.nmake %1 %2 %3 %4 %5 %6 %7 %8 %9
运行之后,打开projects下的goahead-windows-default.sln就可以编译了
如果要调试,需要设置调试目录为 ../../test,加上参数-v即可
可以选择启动项目为test或者goahead.
