之所以报错是缺少nginx的三方插件,下面介绍安装nginx的第三方插件,插件很多直介绍三个
方式一:
下载 ngx_openresty,该集成包中有:Nginx,Lua或Luajit,ngx_lua,以及一些有用的Nginx第三方模块。
安装步骤:
- ./configure --with-luajit
- make
- make install
安装完成,个人建议第一种安装方便简单,另外这个版本还提供了很多的组件,安装不会出现错误。
方式二:
Ngx_lua手动编译进Nginx。
首先,我的 Nginx 安装路径为:/usr/local/nginx。
我将尝试编译的两个模块:echo,lua。
所需要的模块如下:
liujit http://luajit.org
lua http://www.lua.org
ngx_devel_kit https://github.com/simpl/ngx_devel_kit
echo-nginx-module https://github.com/agentzh/echo-nginx-module
lua-nginx-module https://github.com/chaoslawful/lua-nginx-module
安装步骤:
1、Luajit2.0.2(推荐)
wget http://luajit.org/download/LuaJIT-2.0.2.tar.gz tar zxvf LuaJIT-2.0.2.tar.gz cd LuaJIT-2.0.2 make sudo make install
安装lua
tar-zxvf lua-5.2.0.tar.gz
cd lua-5.2.0
make linux
make install
完成安装.
如果遇到
lua.c:67:31: fatal error: readline/readline.h: No such file or directory
说明缺少libreadline-dev依赖包
centos: yum install readline-devel
debian: apt-get install libreadline-dev.
下面需要配置一下 luajit 或 lua 的环境变量(Nginx编译时需要):
-- luajit -- # tell nginx's build system where to find LuaJIT: export LUAJIT_LIB=/path/to/luajit/lib export LUAJIT_INC=/path/to/luajit/include/luajit-2.0.2 -- lua -- # or tell where to find Lua if using Lua instead: export LUA_LIB=/path/to/lua/lib export LUA_INC=/path/to/lua/include
我的测试环境里,配置如下:
export LUAJIT_LIB=/usr/local/luajit/lib export LUAJIT_INC=/usr/local/luajit/include/luajit-2.0
2、安装 ngx_devel_kit (NDK) 模块
cd /usr/local git clone https://github.com/simpl/ngx_devel_kit.git
下载完成后,将在 /usr/local/ 目录下生成子目录 ngx_devel_kit。
3、安装 lua-nginx-module 模块
cd /usr/local git clone https://github.com/chaoslawful/lua-nginx-module.git
下载完成后,将在 /usr/local/ 目录下生成子目录 lua-nginx-module。
4、重新编译Nginx,需要注意编译顺序!
./configure --prefix=/usr/local/nginx \ --with-ld-opt="-Wl,-rpath,$LUAJIT_LIB" \ --add-module=/usr/local/ngx_devel_kit \ --add-module=/usr/local/echo-nginx-module \ --add-module=/usr/local/lua-nginx-module make -j2 make install
注释:重新编译 Nginx 二进制,Nginx 需要 quit 再启动。而普通配置更新则 reload 即可:
kill -HUP `cat /path/nginx/logs/nginx.pid`
/usr/local/nginx/sbin/nginx -s reload
模块编译成功!
重启Nginx服务器!
在编译安装 Nginx 的第三方模块时,碰到一个错误:
/usr/local/nginx/sbin/ngxin -s reload
/usr/local/nginx/sbin/nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory
百事不得其解,后来Google之,发现了解决办法。
在 Nginx 编译时,需要指定 RPATH,加入下面选项即可:
./configure --with-ld-opt="-Wl,-rpath,$LUAJIT_LIB"
或者
export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH
5、测试Lua
在Nginx.conf 配置文件中,加入以下代码:
location /echo {
default_type 'text/plain';
echo 'hello echo';
}
location /lua {
default_type 'text/plain';
content_by_lua 'ngx.say("hello, lua")';
}
重启Nginx服务器:
/usr/local/nginx/sbin/nginx -s reload
使用curl测试:
[root@localhost] curl http://localhost/echo
hello echo
[root@localhost] curl http://localhost/lua
hello lua
测试结果表明,两个模块都安装成功!
