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
系统环境:centos/redhat
安装前准备好如下软件包
· nginx 地址:
· luajit 地址:
· HttpLuaModule 地址:
1. 下载安装LuaJIT
# cd /usr/local/src
# wget
# 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
# tar -xzvf v0.8.6
3. 安装nginx
3.1 安装
# cd /usr/local/src/
# wget
# 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
hello, ttlsa lua //使用curl测试

nginx ngx_lua的安装到此结束
