问题

使用service nginx configtest测试配置文件时提示unknown directive "google" in /etc/nginx/sites-enabled/google:10

测试环境

Ubuntu 14.04.1 LTS

操作步骤

原始nginx版本

root@Ubuntu14041:~# nginx -V
nginx version: nginx/1.8.0
built by gcc 4.8.2 (Ubuntu 4.8.2-19ubuntu1) 
configure arguments: --prefix=/usr/local/nginx --sbin-path=/usr/local/bin

编译更新nginx

root@Ubuntu14041:~# apt-get update
root@Ubuntu14041:~# apt-get install -y build-essential git gcc g++ make nginx
root@Ubuntu14041:~# service nginx stop
root@Ubuntu14041:~# wget "http://nginx.org/download/nginx-1.8.0.tar.gz"
root@Ubuntu14041:~# git clone https://github.com/cuber/ngx_http_google_filter_module
root@Ubuntu14041:~# git clone https://github.com/yaoweibin/ngx_http_substitutions_filter_module
root@Ubuntu14041:~# apt-get install -y libpcre3-dev libssl-dev zlib1g-dev libxslt1-dev libgd-dev libgeoip-dev
root@Ubuntu14041:~# tar -xzf nginx-1.8.0.tar.gz 
root@Ubuntu14041:~# cd nginx-1.8.0
root@Ubuntu14041:~/nginx-1.8.0# ./configure --prefix=/usr/local/nginx --sbin-path=/usr/local/bin --add-module=../ngx_http_google_filter_module --add-module=../ngx_http_substitutions_filter_module
root@Ubuntu14041:~/nginx-1.8.0# make && make install && echo "Done"

新版本

root@Ubuntu14041:~/nginx-1.8.0# nginx -V
nginx version: nginx/1.8.0
built by gcc 4.8.2 (Ubuntu 4.8.2-19ubuntu1) 
configure arguments: --prefix=/usr/local/nginx --sbin-path=/usr/local/bin --add-module=../ngx_http_google_filter_module --add-module=../ngx_http_substitutions_filter_module

生成SSL证书

root@Ubuntu14041:~/nginx-1.8.0# mkdir -p /etc/nginx/ssl
root@Ubuntu14041:~/nginx-1.8.0# openssl req -x509 -nodes -days 3650 -newkey rsa:2048 -keyout /etc/nginx/ssl/nginx.key -out /etc/nginx/ssl/nginx.crt

创建配置文件

root@Ubuntu14041:~/nginx-1.8.0# vim /etc/nginx/sites-enabled/google 
root@Ubuntu14041:~/nginx-1.8.0# cat /etc/nginx/sites-enabled/google    
server {
        listen 80;
        server_name g.huzhifeng.com google.huzhifeng.com;

        access_log  /var/log/nginx/google_http_access.log;
        error_log   /var/log/nginx/google_http_error.log;

        resolver 8.8.8.8;
        location / {
                google on;
        }
}

server {
        listen 443;
        server_name g.huzhifeng.com google.huzhifeng.com;

        access_log  /var/log/nginx/google_https_access.log;
        error_log   /var/log/nginx/google_https_error.log;

        ssl on;
        ssl_certificate /etc/nginx/ssl/nginx.crt;
        ssl_certificate_key /etc/nginx/ssl/nginx.key;

        resolver 8.8.8.8;
        location / {
                google on;
        }
}

测试配置文件

root@Ubuntu14041:~/nginx-1.8.0# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
root@Ubuntu14041:~/nginx-1.8.0# service nginx configtest

root@Ubuntu14041:~/nginx-1.8.0# tail -n 1 /var/log/nginx/error.log

经过调试分析，已经查明了原因，解决了问题，记录下来方便遇到同样问题的朋友参考

问题原因

查看nginx的服务脚本/etc/init.d/nginx和进程路径发现系统中存在两个版本的nginx，使用which nginx看到的是1.8.0的

root@Ubuntu14041:~/nginx-1.8.0# which nginx
/usr/local/bin/nginx
root@Ubuntu14041:~/nginx-1.8.0# nginx -V
nginx version: nginx/1.8.0
built by gcc 4.8.2 (Ubuntu 4.8.2-19ubuntu1) 
configure arguments: --prefix=/usr/local/nginx --sbin-path=/usr/local/bin --add-module=../ngx_http_google_filter_module --add-module=../ngx_http_substitutions_filter_module

而服务脚本/etc/init.d/nginx对应的是1.4.6，服务进程实际运行的就是该版本的

root@Ubuntu14041:~/nginx-1.8.0# grep -rn "DAEMON=" /etc/init.d/nginx    
14:DAEMON=/usr/sbin/nginx

重新编译

root@Ubuntu14041:~/nginx-1.8.0# service nginx stop
root@Ubuntu14041:~/nginx-1.8.0# cd
root@Ubuntu14041:~# wget "http://nginx.org/download/nginx-1.4.6.tar.gz"
