5.3监控apache nginx

 

5.3.1准备工作

1.网络规划:

cacti:10.10.54.50

##在同一台机器上nginx和apache不能同时开启,因为都为80端口。

nginx && apche:10.10.54.54

2.软件下载

服务器器端:

wget http://ftqzy-it-code.googlecode.com/files/ApacheStats_0.8.2.zip

wget http://autosetup1.googlecode.com/files/cacti-nginx.tar.gz

yum -y install perl-libwww-perl

yum install cacti

 

客户端:

yum install -y snmpd

wget http://nginx.org/download/nginx-1.4.5.tar.gz

yum install -y httpd

3.修改配置文件

在做监控apache和nginx服务之前,需要能够实现对远程主机的监控

[root@xiao54 ~]# vim /etc/snmp/snmpd.conf

===============================================

# sec.name source community

com2sec notConfigUser 10.10.54.50 public

# group context sec.model sec.level prefix read write notif

access notConfigGroup "" any noauth exact all none none

## incl/excl subtree mask

view all included .1 80

proc mountd

proc ntalkd 4

proc sendmail 10 1

disk / 10000

load 12 14 14

=======================================================

简要说明:
ExtendedStatus On表示的是访问时能看到详细的请求信息,
注意:该设置仅能用于全局设置,不能在特定的虚拟主机中打开或关闭。
启用扩展状态信息将会导致服务器运行效率降低。
Deny from表示禁止访问的地址;
Allow from表示允许访问的地址;

4.重启服务

/etc/init.d/snmpd restart

5.3.2监控apache

//客户端:

1.安装http

yum install -y httpd

2.修改配置文件

[root@xiao54 ~]# vim /etc/httpd/conf/httpd.conf

============================================

LoadModule status_module modules/mod_status.so

ExtendedStatus On

<Location /server-status>

SetHandler server-status

Order deny,allow

Deny from all

Allow from 10.10.54.0/255.255.255.0

</Location>

===========================================

3.重启服务

[root@xiao54 ~]# /etc/init.d/httpd stop

[root@xiao54 ~]# /etc/init.d/httpd start

4.测试页面

 

//服务器端

1.解压插件包

[root@xiao50 softs]# tar xvf ApacheStats_0.8.2.zip

2.复制解压插件到脚本目录

[root@xiao50 ApacheStats_0.8.2]# cp ss_apache_stats.php /web/vhosts/cacti/scripts/

3.更改目录权限

[root@xiao50 ~]# chmod 755 /web/vhosts/cacti/scripts/

//cacti管理界面

1.导入模板

 

2.新建apache主机

 

点击create.

2.添加监控选项

 

 

 

5.3.3监控nginx

//客户端

1.安装nginx

1)解压

[root@xiao54 softs]# tar xvf nginx-1.4.5.tar.gz

2)编译

[root@xiao54 nginx-1.4.5]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module

--with-http_gzip_static_module --with-http_ssl_module

make

make install

3)启动服务

[root@xiao54 ~]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

2.修改配置文件

[root@xiao54 ~]# vim /usr/local/nginx/conf/nginx.conf

==================================================

user nginx nginx;

worker_processes 2;

error_log logs/error.log info;

pid logs/nginx.pid

 

events {

worker_connections 1024;

}

 

http {

include mime.types;

default_type application/octet-stream;

access_log logs/access.log;

sendfile on;

tcp_nopush on;

keepalive_timeout 65;

gzip on;

 

server {

listen 80;

server_name localhost;

location / {

root html;

index index.html index.htm;

}

 

location /NginxStatus {

stub_status on; --启用状态监测

access_log off; --关闭访问日志

}

===============================================

killall -s HUP nginx (令Nginx配置生效)

3.测试

浏览器输入:http://10.10.54.54/NginxStatus

显示Nginx的运行状态页面

Active connections: 2

server accepts handled requests

2 2 1

Reading: 0 Writing: 1 Waiting: 1

对上面显示结果的分析:

active connection--所有打开的连接,包括连接到后端的服务器的。

server accepts handled requests--nginx已经接受2个连接(第一个位置),处理了2个连接(第二个位置),请求的数量(1个连接对应着1个请求)

reading--读取的请求头

writing--读取的请求主体,处理的请求或者写入的应该。

waiting--keepalive连接数,等于active-(reading+writing)。

 

//服务器端

1.解压插件包

[root@xiao50 softs]# tar xvf cacti-nginx.tar.gz

2.复制解压插件到脚本目录

[root@xiao50 cacti-nginx]# cp get_nginx_clients_status.pl /web/vhosts/cacti/scripts/

[root@xiao50 cacti-nginx]# cp get_nginx_socket_status.pl /web/vhosts/cacti/scripts/

3.更改目录权限

[root@xiao50 ~]# chmod 755 /web/vhosts/cacti/scripts/

4. 验证

[root@xiao50 ~]# /web/vhosts/cacti/scripts/get_nginx_clients_status.pl http://10.10.54.54/NginxStatus

##error

no (LWP::UserAgent not found)

solution:

yum -y install perl-libwww-perl

再次验证:

[root@xiao50 ~]# /web/vhosts/cacti/scripts/get_nginx_clients_status.pl http://10.10.54.54/NginxStatus

nginx_active:1 nginx_reading:0 nginx_writing:1 nginx_waiting:0

[root@xiao50 ~]# /web/vhosts/cacti/scripts/get_nginx_socket_status.pl http://10.10.54.54/NginxStatus

nginx_accepts:4 nginx_handled:4 nginx_requests:4

//cacti管理界面

1.导入模板

Console -> Import Templates

从本机选取:

cacti_graph_template_nginx_clients_stat.xml

cacti_graph_template_nginx_sockets_stat.xml

->Import
