OpenNMS 安装说明－精简版

Per-install Checklist:

1. SuSE 10.1 Linux install CD
2. OpenNMS rpm packages for SuSE Linux
3. JDK 1.5 package
4. Tomcat 5.5.20 package

Here we go:

• Insert install CD into Cd/Dvd rom
• Do SuSE Linux mini install
• Logon in OS, run 'yast firewall' to open 8080 tcp port on firewall
• upload all packages to /opt
• untar JDK
• untar Tomcat
• install postgresql through yast; run 'rcpostgresql start'
• Export some variables

export JAVA_HOME=/opt/jdk1.5.0_09
export OPENNMS_HOME=/opt/opennms
export CATALINA_HOME=/opt/apache-tomcat-5.5.20
export PATH=$PATH:$JAVA_HOME/bin

• Test Java and Tomcat

java -version
$CATALINA_HOME/bin/startup.sh

• Modify this file, vi /var/lib/pgsql/data/pg_hba.conf , then run 'rcpostgresql restart'

#local all all ident sameuser
local all all trus
thost all all 127.0.0.1 255.255.255.255 trust
host all all ::1 ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff trust

• install OpenNMS rpm packages; rpm -ivh xxx.rpm
• $OPENNMS_HOME/bin/runjava -s
• $OPENNMS_HOME/bin/install -dis
• $OPENNMS_HOME/bin/install -y -w $CATALINA_HOME/conf/Catalina/localhost
• restart Tomcat
• start OpenNMS; $OPENNMS_HOME/bin/opennms start
• Check opennms status; $OPENNMS_HOME/bin/opennms -v status
• login web console

以上仅仅是我一个偷懒的方法，可以比较快的部署运行OpenNMS。这种方式的好处如下：

1. Mini安装可以是最快的安装，总共只有几百MB就得到一个Linux操作系统
2. SuSE的包管理比较好用，配合一张安装DVD，几乎所有软件招之即来，不需要下载任何东西
3. Java和Tomcat的安装包是从以前的机器上直接把安装目录tar出来的，这也直接解压来用速度比较快。

这个安装方式的缺点：

1. 并不是最优的安装，没用设置服务的自动重启
2. 没用优化PostgreSQL
3. 没用优化Java和Tomcat；ONMS是java应用，性能可能会是个问题
4. 没用对ONMS做任何配置

• Post-install Checklist:
  Change Admin password for ONMS
  customize ONMS per your requirements
  optimize Tomcat/Postgresql/ONMS configuration
