nginx + ngx_lua安装测试

nginx lua模块淘宝开发的nginx第三方模块,它能将lua语言嵌入到nginx配置中,从而使用lua就极大增强了nginx的能力.nginx以高并发而知名,lua脚本轻便,两者的搭配堪称完美.接下来请看如何安装nginx + ngx_lua模块.以及最后来个简单的测试.

由于已经安装了nginx，所以需要重新编译，要保留原来安装的模块。

1.wget http://labs.frickle.com/files/ngx_cache_purge-2.0.tar.gz

 tar -zxvf ngx_cache_purge-2.0.tar.gz 

 cd /data0/software/nginx-1.1.10

2.查看nginx编译安装时的命令，安装了哪些模块
/usr/local/webserver/nginx/sbin/nginx -V 

3.加入需要安装的模块，重新编译
./configure --user=www --group=www --add-module=../ngx_cache_purge-2.0 --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module
make，不要make install会覆盖 
make
4. 替换nginx二进制文件:
cp /usr/local/webserver/nginx/sbin/nginx /usr/local/webserver/nginx/sbin/nginx.bak
cp ./objs/nginx /usr/local/webserver/nginx/sbin/   
(如果出现  “nginx正在忙的提示”  先停止nginx运行
<pre class="brush:php; toolbar: true; auto-links: false;">/usr/local/webserver/nginx/sbin/nginx -s stop </pre>
<span></span>)
5.启动nginx
/usr/local/webserver/nginx/sbin/nginx

系统环境：centos/redhat

安装前准备好如下软件包
· nginx 地址：http://www.nginx.org
· luajit 地址：http://luajit.org/download.html
· HttpLuaModule 地址：http://wiki.nginx.org/HttpLuaModule

1. 下载安装LuaJIT

# cd /usr/local/src

# wget http://luajit.org/download/LuaJIT-2.0.2.tar.gz

# tar -xzvf LuaJIT-2.0.2.tar.gz

# cd LuaJIT-2.0.2

# make

出现如下内容表示编译成功

OK        Successfully built LuaJIT

make[1]: Leaving directory `/usr/local/src/LuaJIT-2.0.2/src'

==== Successfully built LuaJIT 2.0.2 ====

# make install

出现如下内容，表示安装成功

==== Successfully installed LuaJIT 2.0.2 to /usr/local ====

2. 下载准备nginx lua模块

# cd /usr/local/src

# wget https://github.com/chaoslawful/lua-nginx-module/archive/v0.8.6.tar.gz

# tar -xzvf v0.8.6

3. 安装nginx

3.1 安装

# cd /usr/local/src/

# wget http://nginx.org/download/nginx-1.4.2.tar.gz

# tar -xzvf nginx-1.4.2.tar.gz

# cd nginx-1.4.2

//先导入环境变量,告诉nginx去哪里找luajit

# export LUAJIT_LIB=/usr/local/lib

# export LUAJIT_INC=/usr/local/include/luajit-2.0

# ./configure --prefix=/usr/local/nginx-1.4.2 --add-module=../lua-nginx-module-0.8.6

# make -j2

# make install

3.1 常见错误

# /usr/local/nginx-1.4.2/sbin/nginx -v

./objs/nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory

解决方法：

# ln -s /usr/local/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2

4. nginx lua配置
nginx配置文件加入如下配置：

location ~* ^/2328(/.*) {

      default_type 'text/plain';

      content_by_lua 'ngx.say("hello, ttlsa lua")';

}

5. 启动测试
5.1 启动nginx

# /usr/local/nginx-1.4.2/sbin/nginx

5.2 访问测试

# curl http://test.ttlsa.com/2328/

hello, ttlsa lua //使用curl测试
