I know this documentation isn't finished. I have too few time to spend on it, and would really need help.

I'm running SME8B6 and trying to install zabbix from source (had 1.8.5 now on my server).
 +
I'd like to start to create packages to RHEL5/Centos5 and update packages available as soon as SME8 is released. Maybe we can use the http://wiki.contribs.org/SME8.0_Contribs_QA area for tell everyone our efforts: http://wiki.contribs.org/index.php?title=SME8.0_Contribs_QA&action=edit&section=118
 +
 +
I've already compiled 1.8.5 for both sme7 and SME8, those package are available in our repo ([[Fws]]). I havne't pushed this version in smecontribs repo because the web interface is not compatible with PHP4, so it would break compatibility with standard SME7, but the agent, proxy and server packages works. I need to add a note to the wiki page about this.

== upgrade 4.2.6 to 4.4.4 ==
 +
 +
you will need to change encoding for the db
 +
 +
first
 +
  service zabbix-server stop
 +
  mysqldump zabbixdb >zabbixdb.sql
 +
  echo 'ALTER TABLE `zabbixdb`.`problem_tag` DROP INDEX `problem_tag_1`, ADD INDEX `problem_tag_1` (`eventid`, `tag` (100), `value`(100));' |mysql
 +
  mysql --batch --skip-column-names --execute 'select concat("alter table ",TABLE_SCHEMA,".",TABLE_NAME," CONVERT TO CHARACTER SET utf8 COLLATE utf8_bin;")
 +
from information_schema.TABLES where TABLE_SCHEMA="zabbixdb"' |mysql
 +
  service zabbix-server start
 +
 +
 +
then go to the web interface, it will prompt you again for the configuration of the db
 +
 +
== migrate manually from one server to another ==
 +
 +
save files and config on old server
 +
 +
cd /root
 +
touch zabconfig
 +
chmod 0700 zabconfig
 +
config print zabbix-agent |sed 's/[=|]/ /g ; s/^/config set /' >zabconfig
 +
config print zabbix-server |sed 's/[=|]/ /g ; s/^/config set /' >>zabconfig
 +
# smeserver-zabbix-server smeserver-zabbix-agent smeserver-zabbix-proxy
 +
if [ -d /etc/zabbix ]; then
 +
  for F in /etc/zabbix/*; do
 +
    rpm -qf "$F" >/dev/null 2>&1 || echo "$F" >>dir.list
 +
  done
 +
fi
 +
if [ -d /etc/zabbix/zabbix_agentd.conf.d ]; then
 +
  for F in /etc/zabbix/zabbix_agentd.conf.d/*; do
 +
    rpm -qf "$F" >/dev/null 2>&1 || echo "$F" >>dir.list
 +
  done
 +
fi
 +
if [ -d /var/lib/zabbix/bin ]; then
 +
  for F in /var/lib/zabbix/bin/*; do
 +
    rpm -qf "$F" >/dev/null 2>&1 || echo "$F" >>dir.list
 +
  done
 +
fi
 +
echo "/var/lib/zabbix/tmp/" >>dir.list
 +
echo "/root/zabconfig"  >>dir.list
 +
tar cvzf zabbix.tgz -T dir.list --xattrs
 +
mysqldump --ignore-table=mysql.event --single-transaction --add-drop-table -QB "$(config getprop zabbix-server DbName)" | gzip -c > /root/zabbix.sql.gz
 +
 +
then scp to your new server(assuming you SCP from SME9 to SME10, you need to enable a common cipher
 +
scp -c aes128-ctr /root/zabbix.tgz /root/zabbix.sql.gz root@newip:/root
 +
 +
then, on new server, restore  the data
 +
tar -zxf zabbix.tgz --directory /
 +
then restore the config keys
 +
bash zabconfig
 +
then restore the mysqldb, assuming you already had installed mariadb105 on sme10
 +
zcat zabbix.sql.gz |sed 's/ENGINE=MyISAM/ENGINE=InnoDB/g'|mysql105
 +
create user give him privileges
 +
echo "CREATE USER IF NOT EXISTS `config getprop zabbix-server DbUser`@localhost IDENTIFIED BY '`config getprop zabbix-server DbPassword`';"| mysql105
 +
echo "GRANT ALL PRIVILEGES ON `config getprop zabbix-server DbName`.* TO `config getprop zabbix-server DbUser`@localhost; FLUSH PRIVILEGES;" | mysql105
 +
 +
then follow the wiki procedure to install zabbix z50, including the informations about upgrading your database before installing
 +
 +
== Zabbix db  partitionning ==
 +
 +
for huge db with >200 hosts

 +
 +
== SNMP ==
 +
 +
in case you need to install MIBS, yo will need last version of git from wandisco if you are on SME 10
 +
will also need to install tree rpm
 +
 +
then
 +
 +
git clone https://github.com/jeonghanlee/snmp-mibs-downloader-env.git
 +
cd snmp-mibs-downloader-env
 +
make init
 +
make install
 +
make get
