YUM安装Zabbix5.4启动失败usmAES192教程
说明：
通过zabbix官网YUM方式安装zabbix5.4后，zabbix server启动失败提示“
/usr/sbin/zabbix\_server: symbol lookup error: /usr/sbin/zabbix\_server: undefined symbol: usmAES192PrivProtocol
”
操作系统环境:
[root@zbxserver1 ~]# uname -a
Linux zbxserver1 4.18.0-193.el8.x86\_64 #1 SMP Fri May 8 10:59:10 UTC 2020 x86\_64 x86\_64 x86\_64 GNU/Linux
[root@zbxserver1 ~]# cat /etc/redhat-release
CentOS Linux release 8.2.2004 (Core)
Zabbix5.4安装包：
Zabbix5.4启动失败
[root@zbxserver1 ~]# systemctl restart zabbix-server

错误原因：
由于使用系统镜像中的net-snmp-libs-5.8.安装包，不支持usmAES192 privacy protocol，所以导致zabbix-server启动失败。
解决方法：
根据这篇文章的思路，升级net-snmp到高版本。访问Centos8 YUM仓库下载rpm或者通过网络YUM源方式升级到net-snmp-libs-5.8.18。
YUM源配置参考：
[root@zbxserver1 ~]# cat /etc/yum.repos.d/CentOS-Base.repo
[base]
name=CentOS-$releasever - Base - mirror.centos.org
failovermethod=priority
baseurl=http://mirror.centos.org/centos/$releasever/BaseOS/$basearch/os/
gpgcheck=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-Official
\#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras - mirror.centos.org
failovermethod=priority
baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/os/
gpgcheck=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-Official
#additional packages that extend functionality of existing packages
[AppStream]
name=CentOS-$releasever - AppStream - mirror.centos.org

baseurl=http://mirror.centos.org/centos/$releasever/AppStream/$basearch/os/
gpgcheck=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-Official
升级NET-SNMP：
确认NET-SNMP是否支持AES192：
[root@zbxserver1 ~]# ldd /usr/sbin/zabbix\_server|grep -i snmp
libnetsnmp.so.35 => /lib64/libnetsnmp.so.35 (0x00007fb212cb1000)
[root@zbxserver1 ~]# nm -D /lib64/libnetsnmp.so.35 |grep -i aes
