[root@zabix-66 ~]# mysql_secure_installation ``` ###密码配置为zabbix,其他步骤一路回车 ``` [root@zabix-66 ~]# mysql -uroot -pzabbix MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin; MariaDB [(none)]> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix'; ``` ### 2.2.4 导入zabbix配置文件 ``` [root@zabix-66 ~]# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -pzabbix zabbix ``` ### 2.2.5 配置zabbix配置文件 ``` [root@zabix-66 ~]# egrep -v "^#|^$" /etc/zabbix/zabbix_server.conf LogFile=/var/log/zabbix/zabbix_server.log LogFileSize=0 PidFile=/var/run/zabbix/zabbix_server.pid SocketDir=/var/run/zabbix DBName=zabbix DBUser=zabbix DBPassword=zabbix SNMPTrapperFile=/var/log/snmptrap/snmptrap.log Timeout=4 AlertScriptsPath=/usr/lib/zabbix/alertscripts ExternalScripts=/usr/lib/zabbix/externalscripts LogSlowQueries=3000 ``` ### 2.2.6 配置php文件,修改时区 ``` [root@zabix-66 ~]# grep "php_value" /etc/httpd/conf.d/zabbix.conf php_value max_execution_time 300 php_value memory_limit 128M php_value post_max_size 16M php_value upload_max_filesize 2M php_value max_input_time 300 php_value always_populate_raw_post_data -1 php_value date.timezone Asia/Shanghai ``` ### 2.2.7 启动Apache Web服务器 ``` [root@zabix-66 ~]# systemctl start httpd ``` ### 2.2.8 登录web界面进行设置 ``` http://192.168.56.66/zabbix/setup.php ```        帐号Admin密码zabbix  设置中文  ## 2.3 zabbix-agent安装部署 ### 2.3.1 安装zaxbbix-agent ``` [root@zabix-66 ~]# yum install zabbix-agent ``` ### 2.3.2 zabbix-agent安装配置 ``` [root@zabix-66 ~]# egrep -v "^#|^$" /etc/zabbix/zabbix_agentd.conf PidFile=/var/run/zabbix/zabbix_agentd.pid LogFile=/var/log/zabbix/zabbix_agentd.log LogFileSize=0 Server=192.168.56.66 ServerActive=192.168.56.66 Hostname=Zabbix server Include=/etc/zabbix/zabbix_agentd.d/*.conf ``` ### 2.3.3 启动zabbix-agent服务 ``` [root@zabix-66 ~]# systemctl start zabbix-agent [root@zabix-66 ~]# systemctl status zabbix-agent ``` ## 2.4 添加监控主机     ## 2.5 修复乱码 查看客户端的图表时会显示中文字符乱码  解决方法:安装字体并替换现有字体 ``` [root@zabix-66 ~]# yum install wqy-microhei-fonts -y [root@zabix-66 ~]# cp /usr/share/zabbix/fonts/graphfont.ttf{,.bak} [root@zabix-66 ~]# cp /usr/share/fonts/wqy-microhei/wqy-microhei.ttc /usr/share/zabbix/fonts/graphfont.ttf cp：是否覆盖"/usr/share/zabbix/fonts/graphfont.ttf"？ y [root@zabix-66 ~]# ``` 再次刷新页面发现已经是中文了  ## 2.6 报错 客户端连接报错内容: ``` Received empty response from Zabbix Agent at [192.168.56.66].
