缘由
随着功能需求的深入, openresty领域的包已经不够用了, 需要lua领域本身累积的库, 也就是luarocks.
本文讲解了windows 10桌面和ubuntu server两套系统的方法
Ubuntu Server
比较简单, 无脑敲命令即可
$ wget https://luarocks.org/releases/luarocks-2.4.1.tar.gz
$ tar zxpf luarocks-2.4.1.tar.gz
$ cd luarocks-2.4.1
./configure --prefix=/usr/local/openresty/luajit
--with-lua=/usr/local/openresty/luajit/
--lua-suffix=jit
--with-lua-include=/usr/local/openresty/luajit/include/luajit-2.1
make build && make install
安装luasql-postgres
apt-get install libpq-dev
luarocks PGSQL_INCDIR=/usr/include/postgresql/ install luasql-postgres
mysql同理. 安装之后
luarocks install luasql-mysql MYSQL_INCDIR=/usr/include/mysql
禁用ssh密码方式登录
vim /etc/ssh/sshd_config
PasswordAuthentication no
Windows 10
这个就比较复杂了.
安装MinGW
其实这个是可选项, 如果你的系统路径能找到MSVC的编译器, 那么这一步可以忽略.
为了让以后windwos进行linux相关的作业简单点, 长痛不如短痛, 干脆就装了MinGW吧.
- 点击此处下载:https://sourceforge.net/projects/mingw/files/latest/download?source=files
- 双击
mingw-get-setup.exe, 记得勾选图形界面(默认是勾选的), 这样会让你选择具体安装哪些东西时比较方便 - 在MinGW Installer图形界面勾选
mingw32-base, 然后开始在线安装.
国内网速不是很好,断断续续的, 可能要等半天. 但最终我还是安装上了.
按默认路径安装你会发现C:MinGWinmingw32-gcc.exe这个玩意出现, 它就是luarocks要的东西.最后把C:MinGWin加入windows环境变量
下载luarocks
以2.4.2为例, windows版的下载链接:http://luarocks.github.io/luarocks/releases/luarocks-2.4.2-win32.zip
下载完解压,这里注意下, 以管理员权限打开cmd窗口再cd进luarocks-2.4.2-win32文件夹
配置并安装luarocks
这里, 假设windows上openresty文件夹的路径为:%USERPROFILE%Desktopopenresty
开始安装
在cmd依次敲下面两个命令
set PREFIX=%USERPROFILE%Desktopopenresty
install /P %PREFIX%luarocks /SELFCONTAINED /INC %PREFIX%includeluajit-2.1 /LIB %PREFIX% /BIN %PREFIX% /MW
/P 表示把luarocks安装在openresty的luarocks文件夹
/SELFCONTAINED 表示/TREE和/CONFIG选项的值和/P一致. 这样就所有玩意都在luarocks这个文件里,方便查找.
/INC 表示luajit的include库所在的文件夹
/LIB 表示lua51.dll所在的文件夹
/BIN表示luajit.exe所在的文件夹
/MW表示用mingw32-gcc.exe编译器.
完成安装
正常情况下. 在命令行看到如下输出:
C:UsersxnDesktopluarocks-2.4.2-win32>install /P %PREFIX%luarocks /SELFCONTAINED /INC %PREFIX%includeluajit-2.1 /LIB %PREFIX% /BIN %PREFIX% /MW
C:UsersxnDesktopluarocks-2.4.2-win32>rem=rem --[[

You may want to add the following elements to your paths;
Lua interpreter;
PATH : C:UsersxnDesktopopenresty
PATHEXT : .LUA
LuaRocks;
PATH : C:UsersxnDesktopopenrestyluarocks
LUA_PATH : C:UsersxnDesktopopenrestyluarockslua?.lua;C:UsersxnDesktopopenrestyluarockslua?init.lua
Local user rocktree (Note: %APPDATA% is user dependent);
PATH : %APPDATA%LuaRocksin
LUA_PATH : %APPDATA%LuaRockssharelua5.1?.lua;%APPDATA%LuaRockssharelua5.1?init.lua
LUA_CPATH: %APPDATA%LuaRocksliblua5.1?.dll
System rocktree
PATH : C:UsersxnDesktopopenrestyluarockssystreein
LUA_PATH : C:UsersxnDesktopopenrestyluarockssystreesharelua5.1?.lua;C:UsersxnDesktopopenrestyluarockssystreesharelua5.1?init.lua
LUA_CPATH: C:UsersxnDesktopopenrestyluarockssystreeliblua5.1?.dll
Note that the %APPDATA% element in the paths above is user specific and it MUST be replaced by its actual value.
For the current user that value is: C:UsersxnAppDataRoaming.
提示得很贴心了.把%USERPROFILE%Desktopopenrestyluarocks加入系统路径, 再试试luarocks install luafilesystem
如果一切顺利,你会发现%USERPROFILE%Desktopopenrestyluarockssystreeliblua5.1下出现了lfs.dll, 这就说明安装成功了.
配置nginx路径
包是成功安装好了, 那么怎么让nginx能找到它呢, 在配置文件里这样搞:
http {
lua_package_path "C:UsersxnDesktopopenrestyluarockssystreesharelua5.1?.lua;C:UsersxnDesktopopenrestyluarockssystreesharelua5.1?init.lua;;";
lua_package_cpath "C:UsersxnDesktopopenrestyluarockssystreeliblua5.1?.dll;;";
}
Hello world
最后lua里面require('lfs'), 大功告成
