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

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
