Nginx 监控模块

Nginx 监控模块

1. 编译环境

yum -y install gcc gcc-c++ pcre pcre-devel zlib-devel expat-devel
 
#缺少C++环境提示在安装这个
openssl openssl-devel

2. 软件包

wget http://nginx.org/download/nginx-1.22.0.tar.gz

3. 解压

tar xf nginx-1.22.0.tar.gz -C /usr/local/src

4. 创建用户

useradd -M -s /sbin/nologin nginx

5. 编译安装

cd /usr/local/src/nginx-1.22.0
 
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module
 
make && make install

6. 启动

cd /usr/local/nginx/sbin/
./nginx

7. 是否运行

netstat -lntup | grep nginx

增加监控配置模块模拟

• 先检查是否有http_stub_status_module模块
  • 需要安装的模块是ngx_req_status-master模块、nginx-module-vts模块

先停掉服务

1. 上传包

#Xftp
nginx-module-vts-0.1.18.tar.gz
ngx_req_status-master.zip

2. 放到同级目录

mv /root/* /usr/local/src/

3. 解压

tar xf nginx-module-vts-0.1.18.tar.gz
unzip ngx_req_status-master.zip

4. 备份

cp -rf /usr/local/src/nginx/objs /root/
cp -rf /usr/local/nginx/sbin/nginx /root/
cp -rf /usr/local/nginx/sbin/nginx /usr/local/sbin/nginx/nginx.bak

5.添加补丁

cd /usr/local/src/nginx/
ls
patch -p1 < ../ngx_req_status-master/write_filter-1.7.11.patch

6. 执行编译

还需要把原来的编译环境参数也需要添加过来

./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module \
--add-module=/usr/local/src/nginx-module-vts-0.1.18 \
--add-module=/usr/local/src/ngx_req_status-master

7. 编译

make

8. 查看objs目录

• 会新生成一个nginx命令

#执行,查看有没有新的监控模块
./nginx -V

9. 替换命令

#上面步骤都备份好了，先把源目录/usr/local/nginx/sbin/nginx，移走，安全点，
cd /usr/local/src/nginx/objs/
mv nginx /usr/local/nginx/sbin/

10. 配置文件添加内容

req_status_zone server_name $server_name 256k;
req_status_zone server_addr $server_addr 256k;
req_status_zone server_url  $server_name$uri 256k;
req_status server_name server_addr server_url;
server {
        listen       80;
        server_name  localhost;
        #charset koi8-r;
        #access_log  logs/host.access.log  main;
        location /req-status{
               req_status_show on;
        }
        location /nginx-status{
               stub_status on;
               access_log  on;
        }
        location /vts_status {
        		access_log off;
        		vhost_traffic_status_display;
        		vhost_traffic_status_display_format html;
        }
}

11. 测试

curl localhost/req-status
