使用lua可以为nginx扩展出强大的能力，比如频率限制，访问redis等，本文介绍一下如何安装模块lua-nginx-module

编译安装

• 下载

wget http://luajit.org/download/LuaJIT-2.0.5.tar.gz
wget https://github.com/openresty/lua-nginx-module/archive/refs/tags/v0.10.20.tar.gz
wget https://github.com/vision5/ngx_devel_kit/archive/refs/tags/v0.3.1.tar.gz

• 安装依赖

wget http://luajit.org/download/LuaJIT-2.0.5.tar.gz
tar -zxvf  LuaJIT-2.0.5.tar.gz
cd LuaJIT-2.0.5
make install PREFIX=/usr/local/LuaJIT

• 设置lua环境变量: 添加到/etc/profile

export LUAJIT_LIB=/usr/local/LuaJIT/lib
export LUAJIT_INC=/usr/local/LuaJIT/include/luajit-2.0

• 编译安装

./configure --add-module=../lua-nginx-module-0.10.20 --add-module=../ngx_devel_kit-0.3.1
make & make install

常见问题

• [nginx: [alert] detected a LuaJIT version which is not OpenResty's; many optimizations will be disabled and performance will be compromised (see https://github.com/openresty/luajit2 for OpenResty's LuaJIT or, even better, consider using the OpenResty releases from https://openresty.org/en/download.html)]
• ./configure: error: unsupported LuaJIT version; ngx_http_lua_module requires LuaJIT 2.x. 需要先安装LuaJIT并配置环境变量

export LUAJIT_LIB=/usr/local/lib
export LUAJIT_INC=/usr/local/include/luajit-2.0

• nginx: [alert] failed to load the 'resty.core' module
