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.
如果你是ubuntu系统,请看nginx+lua+redis构建高并发应用

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/nginx- 1.3 . 1
|
5.需要替换nginx二进制文件,先备份一下原来的启动脚本。
[root@vmware1 nginx-1.3.1] # cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
|
这一步很重要，否则加了什么一直找不到，发现这个问题花了几天时间，后面把进程杀了重启才发现！
6.需要把nginx进程杀掉，不然复制会报错
[root@vmware1 nginx-1.3.1] # killall nginx
nginx: no process killed
[root@vmware1 nginx-1.3.1] # cp ./objs/nginx /usr/local/nginx/sbin/
cp : overwrite ` /usr/local/nginx/sbin/nginx ’? yes
|
7.此时，查看下nginx的所有的模块，是否把cache_purge这个模块成功编译进去。
[root@vmware1 nginx-1.3.1] # /usr/local/nginx/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
或者：
#export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
|
8.再次查看编译后的模块信息
[root@vmware1 nginx- 1.3 . 1 ]# /usr/local/nginx/sbin/nginx -V
built by gcc 4.4 . 7 20120313 (Red Hat 4.4 . 7 - 4 ) (GCC)

9. nginx lua配置
nginx配置文件加入如下配置：
Vim usr/local/nginx/conf/nignx.conf
server {
listen 80 ;
server_name 192.168 . 1.5 ;
index index.php;
root / var /www/product/eliteall/v1/hosts;
location ~* ^/ 2328 (/.*) {
default_type 'text/plain' ;
content_by_lua 'ngx.say("hello, ttlsa lua")' ;
}
}
cd / var /www/product/eliteall/v1/hosts
mkdir 2328
|
10.开启nginx.
[root@vmware1 nginx-1.3.1] # /usr/local/nginx/sbin/nginx
[root@vmware1 nginx-1.3.1] # netstat -anpt | grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 6205 /nginx
|
11.访问测试
# curl http://192.168.1.5/2328/
hello, ttlsa lua // 使用curl测试
|
