zabbix 4.2 的安装和设置（mysql57----centos7）

一、安装RPM
[root@localhost ~]# rpm -ivh https://repo.zabbix.com/zabbix/4.2/rhel/7/x86_64/zabbix-release-4.2-1.el7.noarch.rpm

二、安装相关软件
[root@localhost ~]# yum install mysql-server httpd php -y
[root@localhost ~]# yum install zabbix-server-mysql zabbix-web-mysql -y
[root@localhost ~]# yum install zabbix-agent -y

三、创建数据库、导入zabbix需要的表、创建用户并授权

第一次启动mysql，会在日志文件中生成root用户的一个随机密码，使用下面命令查看该密码
[root@localhost ~]# grep 'temporary password' /var/log/mysqld.log

修改root用户密码
[root@localhost ~]# mysql -u root -p
Enter password:

mysql> alter user 'root'@'localhost' identified by 'p@$$w0rd';

创建数据库
mysql> create database zabbix;

导入zabbix需要的表
[root@localhost ~]# zcat /usr/share/doc/zabbix-server-mysql-4.2.3/create.sql.gz | mysql -uroot -p zabbix

创建用户并授权
mysql> create user zabbix@'localhost' identified by 'p@$$w0rd-zabbix';
mysql> grant all privileges on zabbix.* to zabbix@'localhost';
mysql> flush privileges;

四、编辑文件/etc/zabbix/zabbix_server.conf加入server信息

SocketDir=/var/run/zabbix
DBName=zabbix
DBUser=zabbix
DBPasswd=p@$$w0rd-zabbix

查看检查配置：
[root@localhost ~]# grep -v '^#' /etc/zabbix/zabbix_server.conf |grep -v '^$'

LogFile=/var/log/zabbix/zabbix_server.log
LogFileSize=0
PidFile=/var/run/zabbix/zabbix_server.pid
SocketDir=/var/run/zabbixs
DBName=zabbix
DBUser=zabbix
DBPassword=Zabbix-123456
SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
Timeout=4
AlertScriptsPath=/usr/lib/zabbix/alertscripts
ExternalScripts=/usr/lib/zabbix/externalscripts
LogSlowQueries=3000
StatsAllowedIP=127.0.0.1

DBName=zabbix                            #zabbix所属数据库名称 
DBUser=zabbix                            #zabbix所属数据库用户 
DBPassword=www.xxxxxx.com                #zabbix数据库密码 
StartPollers=30                        　#轮询的初始值（0-1000） 
StartIPMIPollers=4                       #IPMI轮询的初始值（0-1000） 
StartPollersUnreachable=30              # 轮询不可达的主机数（包括IPMI 0-1000） 
StartTrappers=8                        　#捕获的初始值（0-1000） 
StartPingers=4                          #ping的初始值（0-1000） 
StartDiscoverers=0                      #自动发现的初始值（0-250） 
CacheSize=384M                          #缓存大小 
CacheUpdateFrequency=300                #缓存更新的频率 
StartDBSyncers=8                        #数据库同步时间 
TrendCacheSize=128M                     #总趋势缓存大小 
AlertScriptsPath=/usr/bin               #脚本的存放位置 
LogSlowQueries=1000                     #日志慢查询设定

五、修改时区：
vim /etc/httpd/conf.d/zabbix.conf
date.timezone = Asia/Shanghai

解决中文乱码
yum -y install wqy-microhei-fonts
cp /usr/share/fonts/wqy-microhei/wqy-microhei.ttc /usr/share/fonts/dejavu/DejaVuSans.ttf

六、设置开机启动
systemctl enable mysqld
systemctl enable zabbix-server
systemctl enable httpd
