基于CentOS 7.x上部署Zabbix 3.4

　　1、安装zabbix最新版epel源：
rpm -ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-1.el7.centos.noarch.rpm　　2、安装zabbix服务端软件包：
yum install zabbix-server-mysql zabbix-web-mysql -y
CentOS 7.x上MySQL数据库叫mariadb，需要安装以下包，请大家自行yum安装：
[root@localhost conf.d]# rpm -qa | grep maria
mariadb-5.5.52-1.el7.x86_64
mariadb-libs-5.5.52-1.el7.x86_64
mariadb-server-5.5.52-1.el7.x86_64
mariadb-test-5.5.52-1.el7.x86_64
mariadb-devel-5.5.52-1.el7.x86_64
[root@localhost conf.d]# mysql_secure_installation    #数据库初始化命令　　3、安装并配置MySQL数据库：
MariaDB [(none)]> create user zabbix identified by '123456';
MariaDB [(none)]> create database zabbix;
MariaDB [(none)]> grant all on zabbix.* to 'zabbix'@'%' identified by '123456';
MariaDB [(none)]> flush privileges;　　4、导入zabbix服务器数据库文件：
[root@localhost ~]# zcat /usr/share/doc/zabbix-server-mysql-3.4.0/create.sql.gz | mysql -u zabbix -p123456 -D zabbix　　5、修改zabbix配置文件：
[root@localhost conf.d]# more /etc/zabbix/zabbix_server.conf | grep -v "#" | grep -v "^$"
LogFile=/var/log/zabbix/zabbix_server.log
LogFileSize=0
PidFile=/var/run/zabbix/zabbix_server.pid
DBName=zabbix
DBUser=zabbix
DBPassword=123456       #只需要设备MySQL数据库zabbix用户对应密码
SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
Timeout=4
AlertScriptsPath=/usr/lib/zabbix/alertscripts
ExternalScripts=/usr/lib/zabbix/externalscripts
LogSlowQueries=3000　　6、修改Apache服务器下，php相关的配置文件：
[root@localhost conf.d]# vi /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    #该项取消注释，并设置对应的时区　　7、配置完成，启动zabbix管理界面完成最后的安装配置，设置zabbix-server与mariadb启动与开机启动：
[root@localhost]# systemctl start zabbix-server
[root@localhost]# systemctl enable zabbix-server
[root@localhost]# systemctl start mariadb
[root@localhost]# systemctl enable mariadb
[root@localhost]# systemctl start httpd
[root@localhost]# systemctl enable httpd　　8、Web登录：http://服务器IP/zabbix，Ok搞定了！
　　

　　9、Zabbix界面显示乱码问题解决：
　　字体存放的目录：/usr/share/zabbix/fonts/
[root@localhost zabbix]# ll /usr/share/zabbix/include/defines.inc.php

[root@localhost zabbix]# sed -i 's/graphfont/DejaVuSans/g' ./include/defines.inc.php

[root@localhost zabbix]# ll fonts/
总用量 17960
-rwxrwxrwx. 1 root root 18387092 8月  24 15:48 DejaVuSans.ttf
lrwxrwxrwx. 1 root root       33 8月  24 13:55 graphfont.ttf -> /etc/alternatives/zabbix-web-font
