nagios npc安装后状态为off的解决方法

 

这几天也在研究naigos整合的事．下面就是我见到过的．网上不少资料．看看下面的这个吧．

１.首先请检查ndo2db的进程是不是二个 
nagios 16825 0.0 0.1 6784 396 ? Ss 19:05 0:00 /usr/local/nagios/bin/ndo2db -c /usr/l 
nagios 17032 0.0 0.3 6784 1268 ? S 19:09 0:00 /usr/local/nagios/bin/ndo2db -c 
2、检查nagios.log日志看看最后有没有 
could not safely copy module '/usr/local/nagios/bin/ndomod-3x.o' 这样的错误 
如果是下面这样是正确的 
ndomod: NDOMOD 1.4b7 (10-31-2007) Copyright (c) 2005-2007 Ethan Galstad ([email protected]) 
[1272020945] ndomod: Successfully connected to data sink. 4897 queued items to flush. 
[1272020951] ndomod: Successfully flushed 4897 queued items to data sink. 
[1272020951] Event broker module '/usr/local/nagios/bin/ndomod-3x.o' initialized successfully. 
上面只是检查工作，解决方法如下 
1、安装nagios3.0 如果是2.9的朋友可以升级安装、升级安装方法的方法很简单

#cd /usr/local/ 
#cp -r nagios/ nagios2.9 
#cd /etc/init.d/ 
#cd nagios nagios2.9 
#cp nagios nagios2.9 
#tar -zvxf nagios-3.0.3.tar.gz 
#cd nagios-3.0.3 
# ./configure --with-command-group=nagios 
#make all 
#make install 
#/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 
可能会报comments downtime警告信息一个错误critical 
vi /usr/local/nagios/etc/nagios.cfg 
#comment_file=/usr/local/nagios/var/comments.dat 加上# 
#downtime_file=/usr/local/nagios/var/downtime.dat 加上#

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 在执行就不会报了 
然后在执行下面 
cd /usr/local/nagios/var/ 
cat comments.dat >>retention.dat 
cat downtime.dat >>retention.dat 
critical错误解决 
check_result_buffer_slots=4096 加上# 
service nagios restart 
2、ndoutils-1.4b7安装此版块、其他版本可能会出程序问题、安装方法如下 
tar zxvf ndoutils-1.4b7.tar.gz 
cd ndoutils-1.4b7 
./configure --with-mysql-lib=/usr/lib/mysql/ --with-mysql-inc=/usr/include/mysql/ 
cp ndomod-3x.o /usr/local/nagios/bin/ndomod-3x.o 
cp ndo2db-3x /usr/local/nagios/bin/ndo2db 
cp ndo2db.cfg /usr/local/nagios/etc/ 
cp ndomod.cfg /usr/local/nagios/etc/ 
进入拷贝的目录给文件加入到nagios用户组 
chown nagios:nagios ndo2db.cfg ndomod.cfg 
chown nagios:nagios ndomod-3x.o ndo2db

然后修改ndo2db.cfg ndomod.cfg配置文件 
cat /usr/local/nagios/etc/ndo2db.cfg |grep -v '^#'|sed /^$/d 
ndo2db_user=nagios 
ndo2db_group=nagios 
socket_type=tcp 
socket_name=/usr/local/nagios/var/ndo.sock 
tcp_port=5668 
db_servertype=mysql 
db_host=127.0.0.1 
db_port=3306 
db_name=cacti 
db_prefix=npc_ 
db_user=cactiuer 
db_pass=cactiuser 
max_timedevents_age=1440 
max_systemcommands_age=10080 
max_servicechecks_age=10080 
max_hostchecks_age=10080 
max_eventhandlers_age=44640 
debug_level=1 
debug_verbosity=1 
debug_file=/usr/local/nagios/var/ndo2db.debug 
max_debug_file_size=1000000

cat /usr/local/nagios/etc/ndomod.cfg |grep -v '^#'|sed /^$/d 
instance_name=default 
output_type=tcpsocket 
output=127.0.0.1 
tcp_port=5668 
output_buffer_items=5000 
buffer_file=/usr/local/nagios/var/ndomod.tmp 
file_rotation_interval=14400 
file_rotation_timeout=60 
reconnect_interval=15 
reconnect_warning_interval=15 
data_processing_options=-1 
config_output_options=2

最后看nagios.cfg最后一行配置文件是否正确 
broker_module=/usr/local/nagios/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.cfg 
这行要和文件和路径对应好

修改完成后重启ndo2db 
kill ndo2db运行的进程 
/usr/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg 然后执行重启 
ps aux 
nagios 16825 0.0 0.1 6784 396 ? Ss 19:05 0:00 /usr/local/nagios/bin/ndo2db -c 
nagios 17032 0.0 0.3 6784 1268 ? S 19:09 0:00 /usr/local/nagios/bin/ndo2db -c 
如果是这样说明ndo2db运行正常
