    Problems with net-snmp

    Hello.
    I installed zabbix for my website. All is like in manual, step by step, but configure without snmp. It worded perfect, but not show me statistic about network, cpu load and some other needed for me. Then I insalled net-snmp(NET-SNMP version: 5.2.1) and snmp-devel. Then, ./configure --with-mysql --with-net-snmp --enable-server && make && make install. Without any problems, great But.... /usr/local/bin/zabbix_server wrote to logs this:
    026729:20060731:183652 Starting zabbix_server. ZABBIX 1.1.1.
    026731:20060731:183652 server #1 started [Alerter]

    026729:20060731:183652 ZABBIX server is up.
    026729:20060731:183652 One server process died. Shutting down...
    026729:20060731:183652 ZABBIX server is down.

    I can't understand what need to do... Any ideas?

      Just to confirm

      I'm on Centos 4.3 and just encountered the same problem with Zabbix 1.1.1:

      net-snmp-utils-5.1.2-11.EL4.6
      net-snmp-libs-5.1.2-11.EL4.6
      net-snmp-5.1.2-11.EL4.6
      net-snmp-devel-5.1.2-11.EL4.6

          Hmmm, so far looks to be an issue perhaps in net-snmp:

          Code:
          Program received signal SIGSEGV, Segmentation fault.
0x4f497373 in ?? ()

          the man page snmp_agent_api states that init_agent() must be called before init_snmp().

          This was working in zabbix1.1beta9 (from which I'm upgrading).

          Thanks

              Red Herring...

              Ok, I finally figured it out. I was compiling zabbix against the precompiled mysql binaries as shipped from mysql.com. The mysql folks compile their libraries and binaries as statically as possible. There ended up being a lot of symbols in those static mysqlclient libraries that were conflicting with the shared libs imported for net-snmp to work properly.

              What I ended up doing was putting a set of self compiled shared mysql libraries and headers on the system and setting up /etc/ld.so.conf to use those as well as having the ./configure script pick them up with something like:

              export CC='gcc -L/usr/local/mysql/shared/lib'

              Zabbix with snmp support works as advertised now.

                  As I mentioned already somewhere else, the problme applies to few distribution only (CentOS). Most of distributions have correct build of MySQL.

                      Very true, I would imagine this would affect anyone who uninstalls the distribution (ie Centos) compiled mysql packages that have shared client libs and installs the newer static ones from mysql.com. This is probably pretty common practice to gain access to the newer mysql 5.x releases.

                      If this becomes a big issue perhaps a sticky post would be in order so others can find the issue relatively easily. Otherwise hopefully this thread will help.

                      Thanks,

                          can we send this issue to the MySQL team?

                          Maybe they are willing to help.
