一、安装zabbix推荐3个博客

二、  
问题一

zabbix server is not running the information displayed may not be current

**解决办法一：**  
查看日志命令 tailf /var/log/zabbix/zabbix\_server.log

19664:20180129:165208.608 [Z3001] connection to database 'zabbix' failed: [2002] Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
    19664:20180129:165208.608 database is down: reconnecting in 10 seconds
    19664:20180129:165218.608 [Z3001] connection to database 'zabbix' failed: [2002] Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

问题很直接的出来的

修改 /etc/zabbix/zabbix\_server.conf

把 DBSocket=/tmp/mysql.sock （估计是原来安装时，自动侦测的）改为 DBSocket=/var/lib/mysql/mysql.sock

在重启服务前显示下服务状态

systemctl status zabbix-server.service
    * zabbix-server.service - Zabbix Server
    Loaded: loaded (/usr/lib/systemd/system/zabbix-server.service; enabled; vendor preset: disabled)
    Active: active (running) since Mon 2018-01-29 16:28:58 CST; 31min ago
    Process: 19622 ExecStop=/bin/kill -SIGTERM $MAINPID (code=exited, status=0/SUCCESS)
    Process: 19662 ExecStart=/usr/sbin/zabbix_server -c $CONFFILE (code=exited, status=0/SUCCESS)
    Main PID: 19664 (zabbix_server)
    CGroup: /system.slice/zabbix-server.service
    `-19664 /usr/sbin/zabbix_server -c /etc/zabbix/zabbix_server.conf
    
    Jan 29 16:28:58 sh01.htsky.cn systemd[1]: Starting Zabbix Server...
    Jan 29 16:28:58 sh01.htsky.cn systemd[1]: PID file /run/zabbix/zabbix_server.pid not readable (yet?) after start.
    Jan 29 16:28:58 sh01.htsky.cn systemd[1]: Started Zabbix Server.

重启zabbix服务  
systemctl restart zabbix-server

**解决办法二：**  
selinux是否关闭。一定要关闭这个，开启selinux会引起一连串问题，甚至zabbix的discovery功能也不能正常使用

关闭SELinux的方法：  
修改/etc/selinux/config文件中的SELINUX="" 为 disabled ，然后重启。  
如果不想重启系统，使用命令setenforce 0  
注：  
setenforce 1 设置SELinux 成为enforcing模式  
setenforce 0 设置SELinux 成为permissive模式  
在lilo或者grub的启动参数中增加：selinux=0,也可以关闭selinux

**解决办法三：**  
zabbix共享内存报错

cannot open log: cannot create semaphore set: \[28\] No space left on device

报错原因：  
kernel.sem参数设置过小，共享内存信号量设置

共享内存：  
可以通过ipcs -lm命令查看目前系统共享内存的参数限制

cat /proc/sys/kernel/sem  
250 32000 100 128

vim /etc/sysctl.conf

kernel.sem =5010 641280 5010 128

sysctl -p /etc/sysctl.conf
