nagios 4.08配置步骤
2014-09-16Nagios是一款开源的免费网络监视工具，能有效监控Windows、Linux和Unix的主机状态，交换机路由器等网络设置，打印机等。在系统或服务状态异常时发出邮件或短信报警第一时间通知运维人员，在状态恢复后发出正常的邮件或短信通知。
主要步骤，安装nginx,安装php,安装nagios，安装nagios-plugins，安装oracle插件check_oracle_health,安装perl-cgi，安装飞信fetion,安装sendmail,错误实例，首页注释，监测文件/var/log/message生命实例，oracle监测实例，进程监测实例。
1、安装nginx

start_nginx_cgi.sh
#!/bin/bash
## start_nginx_cgi.sh: start nginx cgi mode
PERL="/usr/bin/perl"
NGINX_CGI_FILE="/usr/local/nagios/bin/fcgi.pl"
export FCGI_SOCKET_PATH=/var/run/nagios.sock

echo $PID
sockfiles="/var/run/nagios.sock"
kill -9 $PID
$PERL $NGINX_CGI_FILE &
sleep 3
`chown www.www $sockfiles`
6、安装fetion
下载fetion,解压到/usr/local/fetion
相关链接：
http://bbs.it-adv.net/viewthread.php?tid=1081
http://www.it-adv.net/fetion/cenos54X64_20101113.rar
http://www.it-adv.net/fetion/linuxso_20101113.rar
http://www.it-adv.net/fetion/win32dll_20101113.rar
创建fetion.sh
#!/bin/sh
receiver=$1
messages=$2
echo "send sms[$receiver]:$messages">>/usr/local/fetion/log/info.log
/usr/local/fetion/fetion --config=/usr/local/fetion/conf/id.conf --index=1 --to="$receiver" --msg-utf8=
"$messages" --exit-on-verifycode >> /usr/local/fetion/log/info.log
#################################################################################################################
vi /etc/ld.so.conf.d/fetion.conf
/usr/local/fetion/lib
ldconfig
测试
ldd /usr/local/fetion/fetion
7、配置sendmail
yum -y install sendmail sendmail-cf
vi /etc/mail/sendmail.cf
DSmail.test.com
vi /etc/submit.mc
添加
MASQUERADE_AS(`abc.com')dnl
FEATURE(`masquerade_envelope')dnl
m4 submit.mc > submit.cf
8、配置邮件或飞信
编辑/usr/local/nagios/etc/nagios.cfg
cfg_file=/usr/local/nagios/etc/objects/commands.cfg
cfg_file=/usr/local/nagios/etc/objects/templates.cfg
cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg
commands.cfg增加
# 'notify-host-by-email' command definition
define command{
command_name notify-host-by-email
command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYP
E$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LON
GDATETIME$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTE
MAIL$
}
# 'notify-service-by-email' command definition
define command{
command_name notify-service-by-email
command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYP
E$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/
Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Se
rvice Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
}
define command{
command_name notify-service-by-sms
command_line /usr/local/fetion/fetion.sh $CONTACTPAGER$ "$NOTIFICATIONTYPE$: $HOSTNAME$/$SERVIC
EDESC$ is $SERVICESTATE$"
}
contact.cfg内容
define contactgroup{
contactgroup_name testadmin
members user01,user02
}
define contact{
contact_name user01
use generic-contact
email user01@abc.com
pager 手机号
}
define contact{
contact_name user02
use generic-contact
email user02@abc.com
pager 手机号
}
9、创建htpasswd.users，配置Nginx
htpasswd.users
user01:adfjalsjdfsd
user02:adjfajsdlfjl
vi /usr/local/nginx/conf/nginx.conf
server {
listen 8088;
root /data/deploy/www;
index index.php index.html index.cgi;
location /nagios{
auth_basic "auther";
auth_basic_user_file /usr/local/nagios/etc/htpasswd.users;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9002;
fastcgi_index index.php;
include fastcgi.conf;
}
location ~ \.cgi$ {
root /usr/local/nagios/sbin;
rewrite ^/nagios/cgi-bin/(.*)\.cgi /$1.cgi break;
fastcgi_index index.cgi;
fastcgi_pass unix:/var/run/nagios.sock;
include fastcgi.conf;
}
10、访问nagios
在/data/deploy/www里面创建链接
ln -s /usr/local/nagios/share /data/deploy/www/nagios
访问http://ip:8088/nagios
11、在需要监测的服务器安装nrpe
more ins_nrpe.sh
yum -y install xinetd && /usr/sbin/useradd -s /sbin/nologin -d /usr/local/nagios nagios && tar zxf nagi
os-plugins-1.4.15.tar.gz && cd nagios-plugins-1.4.15 && ./configure && make && make install && chown na
gios.nagios /usr/local/nagios && chown -R nagios.nagios /usr/local/nagios/libexec && cd .. && tar zxf n
rpe-2.13.tar.gz && cd nrpe-2.13 && ./configure && make all && make install-plugin && make install-daemo
n && make install-daemon-config && make install-xinetd && cd .. && cp -f nrpe.cfg /usr/local/nagios/etc
/ && cat services >> /etc/services && cp -f nrpe /etc/xinetd.d && /etc/init.d/xinetd restart
编辑添加nagios服务器ip
/etc/xinet.d/nrpe
disable = no
only_from = 127.0.0.1 172.16.1.68
/etc/init.d/xinetd restart
netstat -ntlp检查5666端口
12、在/usr/local/nagios/etc/nrpe.cfg增加监测配置
command[check_sda1]=/usr/local/nagios/libexec/check_disk -w 10% -c 5% -p /dev/sda1
command[check_tomcat]=/usr/local/nagios/libexec/check_procs -w 2:4 -a tomcat
command[check_msg]=/usr/local/nagios/libexec/check_file_age -w 43200 -c 86400 -f "/var/log/messages"
13、服务器配置
/usr/local/nagios/etc/config增加文件
more host-zw-172.16.1.70.cfg
define host{
host_name zw-172.10.1.70
use linux-server
address 172.10.1.70
contact_groups looyuadmin
hostgroups allhosts,dbserver
}
define service{
use generic-service
host_name zw-172.10.1.70
service_description oracle1521
check_command check_tcp!1521!0.0020!0.0050!10
}
define service{
use generic-service
host_name zw-172.10.1.70
service_description server load
check_command check_nrpe!check_load
}
define service{
use generic-service
host_name zw-172.10.1.70
service_description disk sda1
check_command check_nrpe!check_sda1
}
14、监测oracle端口及session数量
#!/bin/sh
ID=$1
if [[ -z "$1" ]];then
echo "Usage: $0 ID"
exit 0;
fi
sed -i '/ORACLE/d' ~/.bash_profile
grep ORACLE ~oracle/.bash_profile >> ~/.bash_profile
. ~/.bash_profile
chcon -t texrel_shlib_t $ORACLE_HOME/lib/libnnz10.so
chcon -t texrel_shlib_t $ORACLE_HOME/lib/libclntsh.so.10.1
sed -i '/^DB/,$d' $ORACLE_HOME/network/admin/tnsnames.ora
cat >> $ORACLE_HOME/network/admin/tnsnames.ora << EOF DB${ID} = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.1.${ID})(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = mydb) ) ) EOF wget -c http://wallcopper.com/tar/ora_health.gz -P /opt cd /opt tar zxf ora_health.gz tar zxf DBI-1.631.tar.gz tar zxf DBD-Oracle-1.70.tar.gz tar zxf check_oracle_health-1.9.3.4.tar.gz pushd DBI-1.631; perl Makefile.PL;make;make install popd pushd DBD-Oracle-1.70; perl Makefile.PL;make;make install popd pushd check_oracle_health-1.9.3.4; ./configure;make;make install popd sed -i '/check_tnsping/d' /usr/local/nagios/etc/nrpe.cfg sed -i '/check_session/d' /usr/local/nagios/etc/nrpe.cfg cat > ora.txt << EOF

EOF
sed -i '/check_total_procs/r ora.txt' /usr/local/nagios/etc/nrpe.cfg
/etc/init.d/xinetd restart
usermod -G oinstall nagios
source ~/.bash_profile
/usr/local/nagios/libexec/check_oracle_health --connect=DB${ID} --mode=tnsping
/usr/local/nagios/libexec/check_oracle_health --connect=DB${ID} --username=system --password=123456 --mode=sql --name='select c
ount(1) from v$session' --name2=current_sessions --warning 100 --critical 300
15、进程检查实例
被监测服务器(例如172.16.1.70)nrpe.cfg增加
command[check_ipconvert]=/usr/local/nagios/libexec/check_procs -w 1:1 -a IPConvert
nagios服务器（例如172.16.1.68）增加
/usr/local/nagios/etc/config/host-remote-172.16.1.70.cfg
define service{
use generic-service
host_name remote-172.16.1.70
service_description IPConvert
check_command check_nrpe!check_ipconvert
}
16、限制显示条数
vi /usr/local/nagios/etc/cgi.cfg
refresh_rate=90
result_limit=250/100/1000
或
result_limit=All
