監控項原型可以依賴於常規的監控項(Item prototypes can depend on regular items)
更靈活的主動式 Agent 自動註冊(More flexible active agent auto-registration)
支援 MySQL 8.0(MySQL 8.0 supported)
Elasticsearch 配置基於日期的索引(Date-based indices setup for Elasticsearch)

1、環境準備

172.16.8.76 qas-zabbix-node01
172.16.8.77 vip地址
172.16.8.78 qas-zabbix-node02

3、架構圖

二、mysql資料安裝（分別在node1、node2安裝）

mysql安裝請參考相關連結：
Centos7.5安裝mysql5.7.24二進位制包方式部署

三、Zabbix安裝及配置（分別在node1、node2安裝）

1、下載原始碼包

相關連結
zabbix官網：https://www.zabbix.com/
zabbix下載：https://sourceforge.net/projects/zabbix/files/ZABBIX%20Latest%20Stable/4.0.2/zabbix-4.0.2.tar.gz/download

2、 YUM安裝PHP環境及所需要依賴包

yum -y install gcc* make php php-gd php-mysql php-bcmath \
php-mbstring php-xml curl curl-devel net-snmp net-snmp-devel  \
perl-DBI httpd mysql-devel libxml2-devel curl-devel unixODBC-devel \
net-snmp-devel OpenIPMI-devel openldap openldap-devel php-ldap libevent-devel

3、建立zabbix使用者及安裝目錄

groupadd zabbix
useradd -g zabbix zabbix
mkdir -pv /app/zabbix4

4、zabbix軟體解壓及安裝

tar -xvf zabbix-4.0.2.tar.gz 
cd zabbix-4.0.2
./configure --prefix=/app/zabbix4 --enable-server --with-mysql --with-net-snmp --with-libcurl --with-libxml2 --with-openipmi --with-unixodbc
make && make install

5、Mysql資料庫建立及匯入基礎資料

create database zabbix character set utf8 collate utf8_bin;
grant all privileges on zabbix.* to [email protected] identified by 'zabbix2018';
grant all privileges on zabbix.* to [email protected]"172.16.8.%" identified by 'zabbix2018';
FLUSH PRIVILEGES;
匯入資料庫
cd /app/tools/zabbix-4.0.2/database/mysql/
mysql -uzabbix -pzabbix2018 zabbix < schema.sql
mysql -uzabbix -pzabbix2018 zabbix < images.sql
mysql -uzabbix -pzabbix2018 zabbix < data.sql

6、修改PHP的配置引數

vim /etc/php.ini
date.timezone= Asia/Shanghai
max_execution_time = 300
post_max_size = 32M
memory_limit = 128M
mbstring.func_overload = 1
max_input_time = 300

7、拷貝zabbix資料到httpd目錄並授權

cd /app/tools/zabbix-4.0.2/
cp -r frontends/php/ /var/www/html/zabbix
ll /var/www/html/
chown -R apache.apache /var/www/html/zabbix/

8、修改配置檔案zabbix_server.conf

建立相關目錄
mkdir /app/zabbix4/{tmp,logs,alertscripts,externalscripts} -p
chown -R zabbix.zabbix /app/zabbix4
修配置檔案如下：
# grep -n ^[a-Z] /app/zabbix4/etc/zabbix_server.conf
38:LogFile=/app/zabbix4/logs/zabbix_server.log
68:PidFile=/app/zabbix4/tmp/zabbix_server.pid
94:DBName=zabbix
110:DBUser=zabbix
118:DBPassword=zabbix2018
125:DBSocket=/tmp/mysql.sock
465:Timeout=4
506:AlertScriptsPath=/app/zabbix4/alertscripts
515:ExternalScripts=/app/zabbix4/externalscripts
551:LogSlowQueries=3000

9、拷貝zabbix服務啟動指令碼

cd /app/tools/zabbix-4.0.2/
cp misc/init.d/fedora/core/zabbix_server /etc/init.d/
vim /etc/init.d/zabbix_server
BASEDIR=/app/zabbix4

10、啟動服務及設定開機啟動

chkconfig --add zabbix_server
chkconfig zabbix_server on
systemctl enable httpd.service
systemctl start httpd.service
/etc/init.d/zabbix_server restart

11、web服務初始化

http://172.16.8.76/zabbix/

ZABBIX4.0.2監控歷史資料存放Elasticsearch及叢集高可用方案

登陸預設使用者名稱:Admin，密碼:zabbix

三、Elasticsearch叢集安裝及配置

1、安裝java

tar -xvf  jdk-8u181-linux-x64.tar.gz -C ../
cd /app/
mv jdk1.8.0_181/ jdk
chown -R root.root jdk

編輯profile檔案，新增jdk環境變數
vim /etc/profile
JAVA_HOME=//app/jdk/jdk1.8.0_181
CLASSPATH=$JAVA_HOME/lib/
PATH=$PATH:$JAVA_HOME/bin
export PATH JAVA_HOME CLASSPATH

2、elasticsearch解壓及安裝

tar -xvf elasticsearch-6.5.1.tar.gz -C ../ 
cd /app/
mv elasticsearch-6.5.1 elasticsearch6.5
chown -R zabbix.zabbix elasticsearch6.5
su - zabbix
mkdir -p /app/elasticsearch6.5/data

3、修改elasticsearch叢集配置檔案

su - zabbix
node01
mkdir -p /app/elasticsearch6.5/data
grep -n ^[a-Z] /app/elasticsearch6.5/config/elasticsearch.yml 
17:cluster.name: app-zabbix
23:node.name: 172.16.8.76
33:path.data: /app/elasticsearch6.5/data
37:path.logs: /app/elasticsearch6.5/logs
43:bootstrap.memory_lock: true
55:network.host: 0.0.0.0
59:http.port: 9200
60:transport.tcp.port: 9300
69:discovery.zen.ping.unicast.hosts: ["172.16.8.76:9300", "172.16.8.78:9300"]
73:discovery.zen.minimum_master_nodes: 1
90:bootstrap.system_call_filter: false
91:http.cors.enabled: true
92:http.cors.allow-origin: "*"

node02
grep -n ^[a-Z] /app/elasticsearch6.5/config/elasticsearch.yml 
17:cluster.name: app-zabbix
23:node.name: 172.16.8.78
33:path.data: /app/elasticsearch6.5/data
37:path.logs: /app/elasticsearch6.5/logs
43:bootstrap.memory_lock: true
55:network.host: 0.0.0.0
59:http.port: 9200
60:transport.tcp.port: 9300
69:discovery.zen.ping.unicast.hosts: ["172.16.8.76:9300", "172.16.8.78:9300"]
73:discovery.zen.minimum_master_nodes: 1
90:bootstrap.system_call_filter: false
91:http.cors.enabled: true
92:http.cors.allow-origin: "*"

4、編輯limits.conf配置檔案

vim /etc/security/limits.conf 
*          soft    nofile  65536
*          hard    nofile  131072
zabbix     soft    memlock unlimited
zabbix     hard    memlock unlimited
zabbix     hard    nproc   4096
zabbix     soft    nproc   4096

5、核心引數優化

vim /etc/sysctl.conf 
vm.max_map_count=262144
vm.swappiness=1

用命令sysctl -p 生效 
sysctl vm.max_map_count 檢視值是否修改， 也可以通過sysctl -w vm.max_map_count=262144 臨時設定值

6、啟動elasticsearch 服務

```.
./elasticsearch -d
