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就极大加强了nginx的能力.nginx以高并发 而知名,lua脚本轻便,二者的搭配堪称完美.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.

若是你是ubuntu系统,请看nginx+lua+redis构建高并发应用

系统环境：centos/redhat

安装前准备好以下软件包
· 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

出现以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
出现以下内容，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配置文件加入以下配置：

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
