Zabbix學習之路（一）之Zabbix安裝

• 1、Zabbix環境準備

[root@linux-node1 ~]#  cat /etc/redhat-release CentOS Linux release 7.4.1708 (Core) [root@linux-node1 ~]#  uname -r 3.10.0-693.5.2.el7.x86_64 [root@linux-node1 ~]# getenforce Disabled [root@linux-node1 ~]# systemctl stop firewalld Failed to stop firewalld.service: Unit firewalld.service not loaded. [root@linux-node1 ~]#  ifconfig eth0|awk -F '[ :]+' 'NR==2{print $3}'
192.168.56.11 [root@linux-node1 ~]# hostname linux-node1 [root@linux-node1 ~]# yum install -y ntpdate [root@linux-node1 ~]# ntpdate time1.aliyun.com [root@linux-node1 ~]# crontab -e */5 * * * * /usr/sbin/ntpdate time1.aliyun.com &>/dev/null

• 2、Zabbix安裝

Zabbix存儲配置包以及yum配置文件 [root@linux-node1 ~]# rpm -ivh http://mirrors.aliyun.com/zabbix/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm
[root@linux-node1 ~]# yum list |grep zabbix Zabbix程序包安裝，以及MySQL、Zabbix-agent [root@linux-node1 ~]# yum install -y zabbix-server-mysql zabbix-web-mysql mariadb-server zabbix-agent

• 3、初始化數據庫

建立Zabbix數據庫以及用戶 [root@linux-node1 ~]# systemctl start mariadb [root@linux-node1 ~]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. Set root password? [Y/n] Y New password: 123456 Re-enter new password: 123456 Password updated successfully! Reloading privilege tables.. ... Success! [root@linux-node1 ~]# mysql -uroot -p Enter password: 123456 Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 10 Server version: 10.1.20-MariaDB MariaDB Server Copyright (c) 2000, 2016, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin; Query OK, 1 row affected (0.00 sec) MariaDB [(none)]> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> flush privileges; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> quit; Bye 導入初始模式和數據: [root@linux-node1 ~]# zcat /usr/share/doc/zabbix-server-mysql-3.0.13/create.sql.gz |mysql -uzabbix -p zabbix Enter password: zabbix [root@linux-node1 ~]# mysql -uroot -p123456 -e "use zabbix;show tables;"

• 4、Zabbix服務器進程啓動

在Zabbix_server.conf編輯數據庫配置 [root@linux-node1 ~]# grep ^[a-Z] /etc/zabbix/zabbix_server.conf LogFile=/var/log/zabbix/zabbix_server.log LogFileSize=0 PidFile=/var/run/zabbix/zabbix_server.pid DBHost=localhost 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 啓動Zabbix服務器進程 [root@linux-node1 ~]# systemctl enable zabbix-server#默認端口爲10051 [root@linux-node1 ~]# systemctl start zabbix-server

• 5、編輯Zabbix前端PHP配置

Apache的配置文件/etc/httpd/conf.d/zabbix.conf，取消註釋，設置正確的時區：Asia/Shanghai [root@linux-node1 ~]# vim /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 經過改變配置文件啓動Apache Web服務器 [root@linux-node1 ~]# vim /etc/httpd/conf/httpd.conf Severname 127.0.0.1:80 [root@linux-node1 ~]# systemctl enable httpd.service Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service. [root@linux-node1 ~]# systemctl start httpd.service [root@linux-node1 ~]# netstat -lntp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name tcp 0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      863/sshd tcp 0      0 127.0.0.1:25            0.0.0.0:*               LISTEN      2085/master tcp6 0      0 :::80                   :::*                    LISTEN      21955/httpd tcp6 0      0 :::22                   :::*                    LISTEN      863/sshd tcp6 0      0 ::1:25                  :::*                    LISTEN      2085/master tcp6 0      0 :::3306                 :::*                    LISTEN      21820/mysqld

• 6、Zabbix的web安裝

step1：

在瀏覽器中，打開Zabbix URL：http：// <server_ip_or_name> / zabbix

step2：

確保知足全部軟件的先決條件。

step3：

輸入鏈接到數據庫的詳細信息。Zabbix數據庫必須已經建立。

step4：

輸入Zabbix服務器的詳細信息。

step5：

查看設置摘要。

step6：

完成安裝，會在/etc/zabbix/web/zabbix.conf.php生成配置文件

當數據庫遇到瓶勁，在進行數據庫拆分的時候，須要修改配置文件/etc/zabbix/web/zabbix.conf.php，指向新的數據庫地址。 [root@linux-node1 ~]# vim /etc/zabbix/web/zabbix.conf.php <?php // Zabbix GUI configuration file.
global $DB; $DB['TYPE']     = 'MYSQL'; $DB['SERVER']   = 'localhost'; $DB['PORT']     = '0'; $DB['DATABASE'] = 'zabbix'; $DB['USER']     = 'zabbix'; $DB['PASSWORD'] = 'zabbix'; // Schema name. Used for IBM DB2 and PostgreSQL.
$DB['SCHEMA'] = ''; $ZBX_SERVER = 'localhost'; $ZBX_SERVER_PORT = '10051'; $ZBX_SERVER_NAME = ''; $IMAGE_FORMAT_DEFAULT = IMAGE_FORMAT_PNG;

step7：

Zabbix前端準備就緒！默認的用戶名是Admin，密碼zabbix。
