监控
使用persona for cacti插件监控mysql
需要mysql调优，安装了一个cacti监控插件 Percona Monitoring Plugins ，
官方地址：http://www.percona.com/software/percona-monitoring-plugins/
1 下载 percona-monitoring-plugins-1.0.0.tar.gz
2 上传 ss_get_mysql_stats.php 到cacti的scripts目录/usr/share/cacti/site/scripts
3 进入cacti的web页面import 数据模版cacti_host_template_percona_mysql_server_ht_0.8.6i-sver1.0.0.xml
4 设置ss_get_mysql_stats.php里的mysql账号链接
5 Percona Monitoring Plugins参考文档：http://form.percona.com/rs/percona/images/Percona_Monitoring_Plugins_100_Operations_Manual.pdf
给ubuntu9.10下的nginx安装nagios监控
1 开权限
root@njava:~# sudo -s root@njava:~# useradd -m -s /bin/bash nagios root@njava:~# passwd nagios Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully root@njava:~# groupadd nagios groupadd: group 'nagios' already exists root@njava:~# usermod -G nagios nagios root@njava:~# groupadd nagcmd root@njava:~# usermod -a -G nagcmd nagios root@njava:~# usermod -a -G nagcmd www-data root@njava:~#
2 下软件
root@njava:~# axel http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.2.1.tar.gz root@njava:~# axel http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.14.tar.gz root@njava:~# tar -xzvf nagios-3.2.1.tar.gz
3 编译设置
root@njava:~# cd nagios-3.2.1 root@njava:~/nagios-3.2.1# ./configure --with-command-group=nagcmd root@njava:~/nagios-3.2.1# make all root@njava:~/nagios-3.2.1# make install root@njava:~/nagios-3.2.1# make install-init root@njava:~/nagios-3.2.1# make install-config root@njava:~/nagios-3.2.1# make install-commandmode
4 安装apache配置，对nagios无用
root@njava:~/nagios-3.2.1# make install-webconf
5 配置nginx
root@njava:~/nagios-plugins-1.4.14# cat /etc/nginx/sites-available/nagios
server {
listen 80;
server_name nagios.njava.com;
access_log /var/log/nginx/nagios.access.log;
location / {
root /usr/local/nagios/share;
index index.php;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
set $path_info "/";
set $real_script_name $fastcgi_script_name;
if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
set $real_script_name $1;
set $path_info $2;
}
fastcgi_param SCRIPT_FILENAME /usr/local/nagios/share/$real_script_name;
fastcgi_param script_name $real_script_name;
fastcgi_param path_info $path_info;
include /etc/nginx/fastcgi_params;
}
location /nagios/images {
alias /usr/local/nagios/share/images;
}
location /nagios/stylesheets {
alias /usr/local/nagios/share/stylesheets;
}
location /cgi-bin {
alias /usr/local/nagios/sbin;
}
location ~ \.cgi$ {
root /usr/local/nagios/sbin;
rewrite ^/cgi-bin/(.*)\.cgi /$1.cgi break;
fastcgi_index index.cgi;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include nginx_fcgi_params;
fastcgi_read_timeout 5m;
fastcgi_pass unix:/var/run/nginx-fcgi.sock;
}
6 安装Nagios Plugins
root@njava:~# tar -xzvf nagios-plugins-1.4.14.tar.gz
root@njava:~# cd nagios-plugins-1.4.14
root@njava:~/nagios-plugins-1.4.14# ./configure --with-nagios-user=nagios --with-nagios-group=nagios
...
... --with-apt-get-command: /usr/bin/apt-get
--with-ping6-command: /bin/ping6 -n -U -w %d -c %d %s
--with-ping-command: /bin/ping -n -U -w %d -c %d %s
--with-ipv6: yes
--with-mysql: no
--with-openssl: yes
--with-gnutls: no
--enable-extra-opts: no
--with-perl: /usr/bin/perl
--enable-perl-modules: no
--with-cgiurl: /nagios/cgi-bin
--with-trusted-path: /bin:/sbin:/usr/bin:/usr/sbin
--enable-libtap: no
root@njava:~/nagios-plugins-1.4.14# make && make install
7 启动nagios相关设置
root@njava:~/nagios-plugins-1.4.14# ln -s /etc/init.d/nagios /etc/rcS.d/ S99nagios
9 nagios设置
用户登录验证
root@njava:~/nagios-plugins-1.4.14#vi /usr/local/nagios/etc/cgi.cfg
use_authentication=0
CGI工作目录
root@njava:~/nagios-plugins-1.4.14#vi /usr/local/nagios/share/config.inc.php $cfg['cgi_base_url']='/cgi-bin';
8 效验nagios执行nagios
root@njava:~/nagios-plugins-1.4.14# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg Things look okay - No serious problems were detected during the pre-flight check root@njava:~/nagios-plugins-1.4.14# /etc/init.d/nagios start
