Nginx安装lua-nginx-module模块
lua-nginx-module模块地址
https://github.com/openresty/lua-nginx-module
It is highly recommended to use OpenResty releases which integrate Nginx, ngx_lua, LuaJIT 2.1, as well as other powerful companion Nginx modules and Lua libraries. It is discouraged to build this module with nginx yourself since it is tricky to set up exactly right. Also, the stock nginx cores have various limitations and long standing bugs that can make some of this modules' features become disabled, not work properly, or run slower. The same applies to LuaJIT as well. OpenResty includes its own version of LuaJIT which gets specifically optimized and enhanced for the OpenResty environment.
如果不听人家的建议，可以按照下面安装
Alternatively, ngx_lua can be manually compiled into Nginx:
- Install LuaJIT 2.0 or 2.1 (recommended) or Lua 5.1 (Lua 5.2 is not supported yet). LuaJIT can be downloaded from the LuaJIT project website and Lua 5.1, from the Lua project website. Some distribution package managers also distribute LuaJIT and/or Lua.
- Download the latest version of the ngx_devel_kit (NDK) module HERE.
- Download the latest version of ngx_lua HERE.
- Download the latest version of Nginx HERE (See Nginx Compatibility)
Build the source with this module:
wget 'http://nginx.org/download/nginx-1.13.6.tar.gz'
tar -xzvf nginx-1.13.6.tar.gz
cd nginx-1.13.6/
# tell nginx's build system where to find LuaJIT 2.0:
export LUAJIT_LIB=/path/to/luajit/lib
export LUAJIT_INC=/path/to/luajit/include/luajit-2.0
# tell nginx's build system where to find LuaJIT 2.1:
export LUAJIT_LIB=/path/to/luajit/lib
export LUAJIT_INC=/path/to/luajit/include/luajit-2.1
# or tell where to find Lua if using Lua instead:
#export LUA_LIB=/path/to/lua/lib
#export LUA_INC=/path/to/lua/include
# Here we assume Nginx is to be installed under /opt/nginx/.
./configure --prefix=/opt/nginx \
--with-ld-opt="-Wl,-rpath,/path/to/luajit-or-lua/lib" \
--add-module=/path/to/ngx_devel_kit \
--add-module=/path/to/lua-nginx-module
# Note that you may also want to add `./configure` options which are used in your
# current nginx build.
# You can get usually those options using command nginx -V
# you can change the parallism number 2 below to fit the number of spare CPU cores in your
# machine.
make -j2
make install
英文不好的可以参考下文
ngx_lua_module 是一个nginx http模块，它把 lua 解析器内嵌到 nginx，用来解析并执行lua 语言编写的网页后台脚本
特性很牛叉，可自行百度查看，这里主要是示范一下，如何在Nginx下安装lua-nginx-module模块
当然，如果你之前没有安装过Nginx,而且嫌安装麻烦，可直接下载openresty安装简单快捷，http://openresty.org/cn/installation.html（阿里的大牛章亦春的作品，膜拜~~~）
1.下载安装LuaJIT 2.1（2.0或者2.1都是支持的，官方推荐2.1）：http://luajit.org/download.html
cd /usr/local/src
wget http://luajit.org/download/LuaJIT-2.1.0-beta2.tar.gz
tar zxf LuaJIT-2.1.0-beta2.tar.gz
cd LuaJIT-2.1.0-beta2
make PREFIX=/usr/local/luajit
make install PREFIX=/usr/local/luajit
2.下载ngx_devel_kit（NDK）模块 ：https://github.com/simpl/ngx_devel_kit/tags，不需要安装
cd /usr/local/src
wget https://github.com/simpl/ngx_devel_kit/archive/v0.2.19.tar.gz
tar -xzvf v0.2.19.tar.gz
3.下载最新的lua-nginx-module 模块 ：https://github.com/openresty/lua-nginx-module/tags，不需要安装
cd /usr/local/src
wget https://github.com/openresty/lua-nginx-module/archive/v0.10.2.tar.gz
tar -xzvf v0.10.2.tar.gz
4.nginx -V查看已经编译的配置
nginx -V笔者的配置如下：
--prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-http_v2_module --with-http_ssl_module --with-ipv6 --with-http_gzip_static_module --with-http_realip_module --with-http_flv_module --with-openssl=../openssl-1.0.2h --with-pcre=../pcre-8.38 --with-pcre-jit --with-ld-opt=-ljemalloc --with-ld-opt=-Wl,-rpath,/usr/local/luajit/lib --add-module=/usr/local/src/ngx_devel_kit-0.2.19 --add-module=/usr/local/src/lua-nginx-module-0.10.2
5.进入之前安装nginx的解压目录，重新编译安装(在nginx -V得到的配置下，加入ngx_devel_kit-0.2.19和ua-nginx-module-0.10.2的目录)，最终的配置如下：
设置环境变量
export LUAJIT_LIB=/usr/local/luajit/lib
export LUAJIT_INC=/usr/local/luajit/include/luajit-2.1
./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-http_v2_module --with-http_ssl_module --with-ipv6 --with-http_gzip_static_module --with-http_realip_module --with-http_flv_module --with-openssl=../openssl-1.0.2h --with-pcre=../pcre-8.38 --with-pcre-jit --with-ld-opt='-ljemalloc' --with-ld-opt="-Wl,-rpath,/usr/local/luajit/lib" --add-module=/usr/local/src/ngx_devel_kit-0.2.19 --add-module=/usr/local/src/lua-nginx-module-0.10.2
6.编译安装
make -j2
make install
7.查看是否编译成功
在/usr/local/nginx/conf/nginx.conf中加入如下代码：
location /hello_lua {
default_type 'text/plain';
content_by_lua 'ngx.say("hello, lua")';
}
重启nginx:
service nginx restart
访问10.211.55.3/hello_lua会出现”hello, lua”表示安装成功
hello, lua
