zabbix 无法启动zabbix-server服务问题解决

问题1：

zabbix-server启动报错 Cannot bind socket to “/var/run/zabbix/zabbix_server_alerter.sock

解决方法：关闭selinux

vim /etc/selinux/config

将config文件中SELINUX=enforcing改为SELINUX=disabled

重启服务器

reboot

问题2：

[file:dbconfig.c,line:90] zbx_mem_malloc(): out of memory (requested 120 bytes)
[file:dbconfig.c,line:90] zbx_mem_malloc(): please increase CacheSize configuration parameter

解决方法：内存用完，增加缓存参数

vim /etc/zabbix/zabbix_server.conf

找到Option: CacheSize，去掉CacheSize前面的#号，并将CacheSize=8M设置为CacheSize=2048M
### 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=2048M

重启zabbix-server服务

systemctl start zabbix-server
