为nginx添加ngx_lua模块并进行安装测试
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.
如果你是ubuntu系统,请看nginx+lua+redis构建高并发应用

系统环境：centos/redhat
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
tar zxvf ngx_devel_kit-0.2.19-r1.tar.gz unzip echo-nginx-module-master.zip
3. 查看nginx以前编译配置信息
/usr/local/nginx/sbin -V configure arguments: --prefix=/usr/local/nginx --pid-path=/var/run/nginx.pid --lock-path=/var/lock/subsys/nginx --error-log-path=/var/log/httpd/error_log --http-log-path=/var/log/httpd/access_log --with-http_ssl_module --with-http_dav_module --with-http_flv_module --with-http_realip_module --with-http_gzip_static_module --with-http_stub_status_module --with-mail --with-mail_ssl_module --with-pcre=../pcre-8.33
4. 重新编译安装nginx增加相关需要的模块
# cd /usr/local/src/ # wget http://nginx.org/download/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 # --prefix=/usr/local/nginx --pid-path=/var/run/nginx.pid --lock-path=/var/lock/subsys/nginx --error-log-path=/var/log/httpd/error_log --http-log-path=/var/log/httpd/access_log --with-http_ssl_module --with-http_dav_module --with-http_flv_module --with-http_realip_module --with-http_gzip_static_module --with-http_stub_status_module --with-mail --with-mail_ssl_module --with-pcre=../pcre-8.33 --add-module=../lua-nginx-module-0.9.5rc2/ --add-module=../echo-nginx-module-master --add-module=../ngx_devel_kit-0.2.19/ # make # make install 注意：这里如果首次安装nginx需要进行make install，如果是为nginx增加相关功能模块，则不需要进行make install操作，要不然会覆盖以前的nignx编译信息。
# 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
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) TLS SNI support enabled configure arguments: --prefix=/usr/local/nginx --pid-path=/var/run/nginx.pid --lock-path=/var/lock/subsys/nginx --error-log-path=/var/log/httpd/error_log --http-log-path=/var/log/httpd/access_log --with-http_ssl_module --with-http_dav_module --with-http_flv_module --with-http_realip_module --with-http_gzip_static_module --with-http_stub_status_module --with-mail --with-mail_ssl_module --with-pcre=../pcre-8.33 --add-module=../lua-nginx-module-0.9.5rc2/ --add-module=../echo-nginx-module-master --add-module=../ngx_devel_kit-0.2.19/
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
nginx lua测试截图
nginx ngx_lua的添加模块到此结束。
