3、服务端集成应用 3.1 Mysql 源码安装省略……# insserv mysqld //创建自启动# insserv -d mysqld# mysqladmin -u root password '111111' //修改root密码3.2 Ngigos 3.2.1安装### 版本：nagios-3.4.1.tar.gz /download/ nagios培训 //问题解决： 问题（1）./installdb nagios数据库时报：failed: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) at ./installdb line 41解决：# mkdir -p /var/run/mysqld # ln -s /tmp/mysql.sock /var/run/mysqld/mysqld.sock问题（2）./installdb nagios数据库时报：DBD::mysql::db do failed: Table 'nagios.nagios_dbversion' doesn't exist at ./installdb line 51.解决：可以忽略，核实nagios数据库59个表即可问题（3）tail -f nagios.log时，提示：ndomod: Could not open data sink!或ndomod: Still unable to connect to data sink.解决：按照以上操作，且进程ps均可见，则尝试重启ndo2db 或nagios或mysql4、centreon集成4.1应用程序安装### 版本：centreon-2.3.9.tar.gz[ /Content-Download/donwload-centreon]Content-Download/donwload-centreon安装参考文档：（1）[ /01-centreon/centreon_web/documentation/01-setup/installation_from_sources/step_05_-_centreon]01-centreon/centreon_web/documentation/01-setup/installation_from_sources/step_05_-_centreon（2）[ /s/blog_5611597901016qd2.html]s/blog_5611597901016qd2.html # tar zxvf centreon-2.3.9.tar.gz# cd centreon-2.3.9# ./install.sh -i //以下是安装过程中需要根据实际路径修改的地方，其他均为y 回车（当然你也可以自己定制）Where is your NDO ndomod binary ?
default to [/usr/sbin/ndomod.o]
> /usr/local/nagios/bin/ndomod.o
/usr/local/nagios/bin/ndomod.o OK
4.2 web installation (1)以下服务均已启动 # /etc/init.d/apache2 start# /etc/init.d/mysqld start# /etc/init.d/ndo2db start# /etc/init.d/nagios start(2)开始安装：
### 备注参考内容： [ /01-centreon/centreon_web/documentation/01-setup/installation_from_sources/step_05_-_centreon]01-centreon/centreon_web/documentation/01-setup/installation_from_sources/step_05_-_centreon

图示1：mysql root密码填写，三个新库密码设置 nagios实施
图示2：配置centreon管理员用户、密码、其他三项自定义
4.3在线安装nagios后 Centreon安装时，其他应用在线安装的，需要修改以下可能出现的路径问题： 监控软件
Where is installed Nagios ? default to [/usr/local/nagios] > /usr/share/nagios3/ Patusr/share/nagios3/ OK Where is your nagios config directory default to [/usr/local/nagios/etc] > /etc/nagios3 Patetc/nagios3 OK Where is your Nagios var directory ? default to [/usr/local/nagios/var] > /var/log/nagios3/ Patvar/log/nagios3/ OK Where is your Nagios plugins (libexec) directory ? default to [/usr/local/nagios/libexec] > /usr/lib64/nagios/plugins Patusr/lib64/nagios/plugins OK /usr/sbin/nagios3 OK Where is your Nagios image directory ? default to [/usr/local/nagios/share/images/logos] > /usr/share/nagios3/htdocs/images/logos/ Patusr/share/nagios3/htdocs/images/logos/ OK Where is your NDO ndomod binary ? default to [/usr/sbin/ndomod.o] > /usr/lib/ndoutils/ndomod-mysql-3x.o /usr/lib/ndoutils/ndomod-mysql-3x.o OK 4.4 Web 安装centreon完成后### 参考链接：[ /?page_id=968]?page_id=968 nagios配置 Finalize Centreon configuration:
Open in webrowser: "<yourserverip>/centreon/", replace "<yourserverip>" with your Centreon server ip address or hostname. Go to: Configuration -> Nagios -> cgi (in sidebar), Press on "CGI.cfg" link Change settings to some options, as writed below: - Physical HTML Path: /usr/share/nagios3/htdocs - URL HTML Path : /nagios3 - Nagios Process Check Command: /usr/lib/nagios/plugins/check_nagios /var/cache/nagios3/status.dat 5 '/usr/sbin/nagios3' Press Save Go to: Configuration -> Nagios -> nagios.cfg (in sidebar), Press on "Nagios CFG 1" link, you should be in "Files" section of the configuration screen. Make sure to set folowing configuration values: - Log File : /var/log/nagios3/nagios.log - Downtime File : /var/lib/nagios3/downtime.dat - Comment File : /var/lib/nagios3/comment.dat - Temp File : /var/cache/nagios3/nagios.tmp - P1 File : /usr/lib/nagios3/p1.pl - Lock File : /var/run/nagios3/nagios3.pid - Object Cache File : /var/cache/nagios3/objects.cache - Status File : /var/cache/nagios3/status.dat - External Command File : /var/lib/nagios3/rw/nagios.cmd Now Press on "Logs Options" tab to go to "Logs Options" section. 开源监控软件 Make sure to set folowing configuration values:
- Log Archive Path : /var/log/nagios3/archives/ - State Retention File : /var/lib/nagios3/retention.dat Press Save Go to: Administration -> Options -> CentStorage (in sidebar) Make sure to set folowing configuration values: - Nagios current log file to parse: /var/log/nagios3/nagios.log Press Save Now let's apply our changes, go to: Configuration -> Nagios Select as below: - Generate Configuration Files - Include Comments - Run Nagios debug (-v) - Move Export Files - Restart Nagios - Method: "External Command" Press Export This will restart Nagios & apply all changes you made in Web Interface. You will do it every time you make changes, e.g. adding/modifying of hosts, commands, contacts, services...etc... nagios安装 The installation of Centreon is completed. Final fixes (very important): Go to terminal console, then... In Debian/Ubuntu the user "nagios" is set to "/bin/false" shell. Because of it "centcore" and "centstorage" daemons won't start. A reason for that is because those daemons use "su -c" command which requires a real shell, so the shell for "nagios" user must be set to "/bin/sh": # usermod -s /bin/sh nagios Apply permissions for Web interface to be able to send "External Commands", perform the following commands to change directory permissions and to make the changes permanent: # invoke-rc.d nagios3 stop # dpkg-statoverride --update --add nagios www-data 2710 /var/lib/nagios3/rw # dpkg-statoverride --update --add nagios nagios 751 /var/lib/nagios3 Add htaccess user with password "P@ssw0rd" for nagios CGI: # htpasswd -bc /etc/nagios3/htpasswd.users nagiosadmin P@ssw0rd Allow SNMP readonly access: # echo "rocommunity public" > /etc/snmp/snmpd.conf If you want to allow SNMP access only for localhost then use this instead: # echo "rocommunity public 127.0.0.1" > /etc/snmp/snmpd.conf # ls -al /usr/lib/nagios/plugins //查看权限，需要具有sudo权限 # cd /usr/lib/nagios/ # chmod -R u+s plugins //权限修改成 ：-rwsr-xr-x ### 不修改权限会报：Warning: This plugin must be either run as root or setuid root. Now, restart the server # reboot 4.5 可能的报错信息（1）报错解决：
Error: Could not create external command file '/var/log/nagios3/rw/nagios.cmd' 解决：mkdir /var/log/nagios3/rw Chown nagios.nagios rw （2）在线安装ndoutils，启动ndo2前一定要修改：/etc/default/ndoutils ENABLE_NDOUTILS=1
