yum安装agent或者proxy报错

配置官方源

rpm -ivh https://repo.zabbix.com/zabbix/4.2/rhel/7/x86_64/zabbix-release-4.2-1.el7.noarch.rpm

yum安装报错： Processing Dependency: libpcre.so.0()(64bit) for package: zabbix-agent-4.2.8-1.el6.x86_64

解决办法，yum源取消检查配置

yum源取消检查配置

对已经安装好的zabbix 报错

查看状态是activating，但是没有相关进程和端口占用

发现如下报错： error while loading shared libraries: libcrypto.so.10: cannot open shared object file: No such file or directory
非root用户可能看不到该报错

解决办法

从其他正常的服务器获取对应lib文件，下载后上传到/usr/lib64 下，权限赋予0755，后创建对应软连接。

cd /usr/lib64

chmod 755 libcrypto.so.1.0.2k
ln -s libssl.so.1.0.2k libssl.so.10
ln -s libcrypto.so.1.0.2k   libcrypto.so.10
ldconfig -v
systemctl  restart  zabbix-agent
systemctl  status  zabbix-agent

agent 启动报错

agent重启失败

systemctl  status zabbix-agent 
journalctl -xeu zabbix-agent.service
