♦防止webshell上传
配置方法如下，nginx编译安装可参考https://blog.whsir.com/post-2134.html
1、下载ngx_devel_kit
cd /usr/local/src wget https://github.com/simpl/ngx_devel_kit/archive/v0.3.0.tar.gz tar zxf v0.3.0.tar.gz
|-------|-----------------------------------------------------------------------------------------------------------| | 1 2 3 | cd /usr/local/src wget https://github.com/simpl/ngx_devel_kit/archive/v0.3.0.tar.gz tar zxf v0.3.0.tar.gz |
2、下载lua-nginx-module
wget https://github.com/openresty/lua-nginx-module/archive/v0.10.11.tar.gz tar zxf v0.10.11.tar.gz
|-----|----------------------------------------------------------------------------------------------------| | 1 2 | wget https://github.com/openresty/lua-nginx-module/archive/v0.10.11.tar.gz tar zxf v0.10.11.tar.gz |
3、安装luajit
wget http://luajit.org/download/LuaJIT-2.0.5.tar.gz tar zxf LuaJIT-2.0.5.tar.gz cd LuaJIT-2.0.5 make make install
|-----------|-------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 | wget http://luajit.org/download/LuaJIT-2.0.5.tar.gz tar zxf LuaJIT-2.0.5.tar.gz cd LuaJIT-2.0.5 make make install |
4、导入环境变量
export LUAJIT_LIB=/usr/local/lib export LUAJIT_INC=/usr/local/include/luajit-2.0
|-----|----------------------------------------------------------------------------------| | 1 2 | export LUAJIT_LIB=/usr/local/lib export LUAJIT_INC=/usr/local/include/luajit-2.0 |
5、编译nginx模块（注意增加模块不需要make install）
cd /usr/local/src/nginx-1.12.2 ./configure --add-module=/usr/local/src/ngx_devel_kit-0.3.0 --add-module=/usr/local/src/lua-nginx-module-0.10.11 --with-ld-opt=-Wl,-rpath,$LUAJIT_LIB make mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak cp objs/nginx /usr/local/nginx/sbin/ systemctl reload nginx
|-------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 | cd /usr/local/src/nginx-1.12.2 ./configure --add-module=/usr/local/src/ngx_devel_kit-0.3.0 --add-module=/usr/local/src/lua-nginx-module-0.10.11 --with-ld-opt=-Wl,-rpath,$LUAJIT_LIB make mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak cp objs/nginx /usr/local/nginx/sbin/ systemctl reload nginx |
PS：如果报错 nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory 解决方法： ln -s /usr/local/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2
|---------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 | PS：如果报错 nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory 解决方法： ln -s /usr/local/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2 |
6、下载ngx_lua_waf
cd /usr/local/nginx/conf wget https://github.com/loveshell/ngx_lua_waf/archive/v0.7.2.tar.gz tar zxf v0.7.2.tar.gz mv ngx_lua_waf-0.7.2 waf
|---------|---------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 | cd /usr/local/nginx/conf wget https://github.com/loveshell/ngx_lua_waf/archive/v0.7.2.tar.gz tar zxf v0.7.2.tar.gz mv ngx_lua_waf-0.7.2 waf |
7、在nginx.conf的http字段内添加以下内容
lua_package_path "/usr/local/nginx/conf/waf/?.lua"; lua_shared_dict limit 10m; init_by_lua_file /usr/local/nginx/conf/waf/init.lua; access_by_lua_file /usr/local/nginx/conf/waf/waf.lua;
|---------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 | lua_package_path "/usr/local/nginx/conf/waf/?.lua"; lua_shared_dict limit 10m; init_by_lua_file /usr/local/nginx/conf/waf/init.lua; access_by_lua_file /usr/local/nginx/conf/waf/waf.lua; |
8、最后重启nginx（reload也可以的）
systemctl restart nginx
|---|-------------------------| | 1 | systemctl restart nginx |
9、验证（看到如下图即表示配置成功）
http://域名或IP地址/index.php?id=../etc/passwd
例如：http://192.168.157.132/index.php?id=../etc/passwd
