opennms介绍

Opennms能够帮助IT管理部门持续的监控分布式的异构系统和网络设备的运行状态，它可以支持SNMP网络管理协议确保管理的扩展性，并且提供非常灵活的定制功能从而有利于管理范围的伸缩。
它内置的故障事件管理以提供故障事件的记录和分析的能力，快速隔离非根源事件并迅速发现故障原因。
Opennms 良好的设计可以快速部署实施，简单友好的图形界面能够使得用户迅速掌握，从而降低操作的复杂度，提高IT管理效率。

搭建步骤

1.环境准备

[root@opennms ~]# cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core) 
[root@opennms ~]# systemctl stop firewalld
[root@opennms ~]# sestatus 
SELinux status:                 disabled

提示：关闭防火墙和selinux，并保证能正常上网
2.添加opennms的yum源

rpm -Uvh http://yum.opennms.org/repofiles/opennms-repo-stable-rhel7.noarch.rpm
rpm --import http://yum.opennms.org/OPENNMS-GPG-KEY

3.安装软件包和依赖包

The following packages will be automatically installed:
opennms: The platform meta package which handles all dependencies from OpenNMS repository.
jicmp6 and jicmp: Java bridge to allow sending ICMP messages from OpenNMS repository.
opennms-core: OpenNMS core services, e.g. Provisiond, Pollerd and Collectd from OpenNMS repository.
opennms-webapp-jetty: OpenNMS web application from OpenNMS repository
jdk1.8: Oracle Java SE Development Kit 8 environment from OpenNMS respository
postgresql: PostgreSQL database server from distribution repository
postgresql-libs: PostgreSQL database from distribution repository

我们知道，它依赖jdk1.8，postgresql，opennms-core，opennms-webapp-jetty
用yum下载太慢了，我都是找到url地址，用迅雷下载，然后直接`上传

这里postgresql我是yum安装的

http://yum.opennms.org/stable/common/jdk/x64/jdk-8u60-linux-x64.rpm
http://yum.opennms.org/stable/common/opennms/opennms-core-18.0.2-1.noarch.rpm
http://yum.opennms.org/stable/common/opennms/opennms-webapp-jetty-18.0.2-1.noarch.rpm

下载完成后，上传

[root@opennms ~]# ls
anaconda-ks.cfg         opennms-core-18.0.2-1.noarch.rpm
jdk-8u60-linux-x64.rpm  opennms-webapp-jetty-18.0.2-1.noarch.rpm

这里我先安装的是postgreSQL

yum install -y postgresql postgresql-server

安装jdk

rpm -ivh jdk-8u60-linux-x64.rpm

安装opennms-core

yum localinstall -y opennms-core-18.0.2-1.noarch.rpm

安装opennms-webapp-jetty-

yum localinstall -y opennms-webapp-jetty-18.0.2-1.noarch.rpm

最后安装opennms

yum -y install opennms

检查安装

[root@opennms ~]# tree -L 1 /opt/opennms/
/opt/opennms/
├── bin
├── contrib
├── data
├── deploy
├── etc
├── jetty-webapps
├── lib
├── logs -> /var/log/opennms
├── share -> /var/opennms
└── system

10 directories, 0 files

安装已经完成，下面是部署配置
4.配置PostgreSQL

postgresql-setup initdb         初始化
systemctl enable postgresql     开机启动
systemctl start postgresql      启动

su - postgres                   切换用户
createuser -P opennms           创建opennms用户，并设置密码，我设置的密码是opennms
createdb -O opennms opennms
psql -c "ALTER USER postgres WITH PASSWORD 'opennms';" 设置超级用户的密码也是opennms
exit                            回到root用户

修改pg_hba.conf

vi /var/lib/pgsql/data/pg_hba.conf
将下面的ident修改为md5
     82 host    all             all             127.0.0.1/32            ident
     83 # IPv6 local connections:
     84 host    all             all             ::1/128                 ident

修改之后的效果

     82 host    all             all             127.0.0.1/32            md5
     83 # IPv6 local connections:
     84 host    all             all             ::1/128                 md5

然后保存退出，平滑重启postgreSQL

systemctl reload postgresql

5.配置opennms，并启动
个人文本有限，觉得还是官方文档说的比较好，就直接贴上来了
编辑下面这个配置文件

vi /opt/opennms/etc/opennms-datasources.xml
Configuration for database authentication in OpenNMS
<jdbc-data-source name="opennms"
                    database-name="opennms"
                    class-name="org.postgresql.Driver"
                    url="jdbc:postgresql://localhost:5432/opennms"
                    user-name="** YOUR-OPENNMS-USERNAME **"
                    password="** YOUR-OPENNMS-PASSWORD **" />

<jdbc-data-source name="opennms-admin"
                    database-name="template1"
                    class-name="org.postgresql.Driver"
                    url="jdbc:postgresql://localhost:5432/template1"
                    user-name="postgres"
                    password="** YOUR-POSTGRES-PASSWORD **" />
    Set the user name to access the OpenNMS database table
    Set the password to access the OpenNMS database table
    Set the postgres user for administrative access to PostgreSQL
    Set the password for administrative access to PostgreSQL

修改完成之后的效果

  <jdbc-data-source name="opennms"
                    database-name="opennms"
                    class-name="org.postgresql.Driver"
                    url="jdbc:postgresql://localhost:5432/opennms"
                    user-name="opennms"
                    password="opennms" />

  <jdbc-data-source name="opennms-admin"
                    database-name="template1"
                    class-name="org.postgresql.Driver"
                    url="jdbc:postgresql://localhost:5432/template1"
                    user-name="postgres"
                    password="opennms" />

/opt/opennms/bin/runjava -s
/opt/opennms/bin/install -dis

等屏刷完

systemctl enable opennms
systemctl start opennms

6.访问opennms
先看下本机的ip

[root@opennms ~]# hostname -I
192.168.56.139
所有我的地址是http://192.168.56.139:8980/opennms

初始账号密码两个admin

到此部署安装完成！
