2.解决报错（please increase CacheSize configuration parameter，请增加 CacheSize 配置参数）

$ vim /data/zabbix_server/etc/

### Option: CacheSize
#       Size of configuration cache, in bytes.
#       Shared memory size for storing host, item and trigger data.
#
# Mandatory: no
# Range: 128K-64G
# Default:
# CacheSize=8M
CacheSize=4096M
#根据自己的资源状态给予，范围是 128K-64G。一般给 2G 就可以解决报错，如果不行可以再增加
