OpenResty 整合 LuaRocks - Linux

安装 LuaRocks

下载地址：https://luarocks.github.io/luarocks/releases

下载并解压

wget https://luarocks.github.io/luarocks/releases/luarocks-3.5.0.tar.gz
tar -zxvf luarocks-3.5.0.tar.gz
cd luarocks-3.5.0

配置编译参数

./configure --prefix=/usr/local/openresty/luarocks --with-lua=/usr/local/openresty/luajit/ --with-lua-include=/usr/local/openresty/luajit/include/luajit-2.1 --with-lua-lib=/usr/local/openresty/lualib

可能出现的错误

找不到unzip命令，执行yum安装即可yum -y install unzip zip

Could not find 'unzip'.
Make sure it is installed and available in your PATH.

configure failed.

正确配置编译参数后输出

编译

make -j8

安装

使用sudo执行，否则可能会无法创建文件夹。

sudo make install

建立软链

在/usr/local/sbin下建立luarocks命令，链接到真实命令/usr/local/openresty/luarocks/bin/luarocks。

ln -s /usr/local/openresty/luarocks/bin/luarocks /usr/local/sbin/luarocks

添加 lua 包路径

修改nginx.conf配置文件，在http节点下，添加lua_package_path和lua_package_cpath属性，链接的lua包路径为，LuaRocks配置编译参数阶段指定的--prefix参数对应的文件夹（一般--prefix设置为OpenResty安装的目录下新建luarocks文件夹）。

$prefix是OpenResty编译安装时指定的--prefix对应的文件夹，且$prefix只适用于lua_package_path/lua_package_cpath属性。

注意：虽然编译安装时指定的--prefix是/usr/local/openresty，但nginx真实的--prefix为/usr/local/openresty/nginx，可使用./nginx -V查看，所以设置LuaRocks路径时指定为$prefix/../luarocks

http {
    lua_package_path '$prefix/z_blog_openresty/src/?.lua;$prefix/../luarocks/share/lua/5.1/?.lua;$prefix/../luarocks/share/lua/5.1/?/init.lua;;';
    lua_package_cpath '$prefix/../luarocks/lib/lua/5.1/?.so;;';
}
