Linux 安裝Zabbix 3.4

01、配置與前提

　　00.1、Linux最小化系統配置 https://www.cnblogs.com/huanu/p/9235558.html 

　　00.2、安裝vim編輯器 yum -y install vim 

　　00.3、zabbix 客戶端安裝 https://www.cnblogs.com/huanu/p/9253777.html 

02、關閉SELinux

sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

03、關閉防火牆

systemctl stop firewalld.service && systemctl disable firewalld.service

　　完成03、04后，用reboot命令重啟一下操作系統，並重新登錄

04、獲取SQL源

rpm -Uvh https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

05、安裝 Zabbix 所需軟件支持包

　　先安裝mysql

yum -y install mysql-* --skip-broken #有沖突的軟件跳過

　　安裝Apache

yum -y install httpd

systemctl start httpd.service #啟動
systemctl stop httpd.service #停止
systemctl restart httpd.service #重啟
systemctl enable httpd.service #開機啟動
systemctl disable httpd.service #開機不啟動

　　安裝php

yum -y install php

　　安裝php擴展

yum -y install php-mysqlnd php-gd libjpeg* php-snmp php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-bcmath php-mhash php-common php-ctype php-xml php-xmlreader php-xmlwriter php-session php-mbstring php-gettext php-ldap php-mysqli --skip-broken

yum -y install wget telnet net-tools python-paramiko gcc gcc-c++ dejavu-sans-fonts python-setuptools python-devel sendmail mailx net-snmp net-snmp-devel net-snmp-utils freetype-devel libpng-devel perl unbound libtasn1-devel p11-kit-devel OpenIPMI unixODBC

06、設置 MySQL 參數（8GB 內存為例）

vim /etc/my.cnf  #不然沒權限保存

　　在my.cnf后面添加以下內容

innodb_file_per_table = 1
innodb_status_file = 1
innodb_buffer_pool_size = 6G
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 16M
innodb_log_file_size = 64M
innodb_support_xa = 0
default-storage-engine = innodb
bulk_insert_buffer_size = 8M
join_buffer_size = 16M
max_heap_table_size = 32M
tmp_table_size = 32M
max_tmp_tables = 48
read_buffer_size = 32M
read_rnd_buffer_size = 16M
key_buffer_size = 32M
thread_cache_size = 32
innodb_thread_concurrency = 8
innodb_flush_method = O_DIRECT
innodb_rollback_on_timeout = 1
query_cache_size = 16M
query_cache_limit = 16M
collation_server = utf8_bin
character_set_server = utf8

　　注：原則上 innodb_buffer_pool_size 需要設置為主機內存的 80%，如果主機內存不是 8GB，以上參數可依據相應比例進行調整，例如主機內存為 16GB，則 innodb_buffer_pool_size 建議設置為 12GB，innodb_log_buffer_size 建議設置為 32M，innodb_log_file_size 建議設置為 128M，以此類推。請注意innodb_buffer_pool_size的值必須是整數，例如主機內存是4G，那么innodb_buffer_pool_size可以設置為3G，而不能設置為3.2G

07、啟動MySQL

systemctl enable mysqld && systemctl start mysqld

08、獲取 MySQL 的 root 初始密碼

grep 'temporary password' /var/log/mysqld.log

[root@localhost ~]# grep 'temporary password' /var/log/mysqld.log
2018-06-23T00:18:25.380389Z 1 [Note] A temporary password is generated for root@localhost: oj8n=R%9)Q1.
[root@localhost ~]# 

oj8n=R%9)Q1. #即是默認mysql密碼

09、進行 MySQL 安全配置
　　配置開始時會用到第 09獲取的初始密碼，建議修改為自定義密碼，其它選項選擇 y 即可

mysql_secure_installation

[root@localhost ~]# mysql_secure_installation
Securing the MySQL server deployment.
Enter password for user root:
The existing password for the user account root has expired.Please set a new password.
New password:

　　密碼改為：Abc2345,.

10、重啟 MySQL

systemctl restart mysqld

11、配置 MySQL 中 zabbix要的庫和賬號權限

[root@localhost ~]# mysql -u root -p（需要輸入第 10步中設置的自定義密碼）

mysql>create database zabbix character set utf8; #創建數據庫
mysql>create user zabbix@'%' identified by 'Abc@2018'; #創建用戶和密碼
mysql>grant all privileges on zabbix.* to zabbix@'%'; #賦權
mysql>flush privileges;
mysql>exit;

12、安裝 Zabbix源

rpm -ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm 
http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/

 13、安裝zabbix

yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-java-gateway zabbix-web

14、導入 zabbix 所需信息

cd /usr/share/doc/zabbix-server-mysql-3.4  #先按Tab鍵補全文件夾全名
zcat create.sql.gz | mysql -uroot zabbix -p  #（需要輸入第 10 步中設置的自定義密碼）

15、配置 zabbix 參數

vim /etc/zabbix/zabbix_server.conf #這個配置要一遍過

　　主要是以下幾個選項參數需要設置（8GB 內存為例）：

　　vim顯示行號命令 ：set number 

119 ### Option: DBPassword
120 #       Database password. Ignored for SQLite.
121 #       Comment this line if no password is used.
122 #
123 # Mandatory: no
124 # Default:
125  DBPassword=Abc@2018

378 ### Option: CacheSize
379 #       Size of configuration cache, in bytes.
380 #       Shared memory size for storing host, item and trigger data.
381 #
382 # Mandatory: no
383 # Range: 128K-8G
384 # Default:
385  CacheSize=512M

403 ### Option: HistoryCacheSize
404 #       Size of history cache, in bytes.
405 #       Shared memory size for storing history data.
406 #
407 # Mandatory: no
408 # Range: 128K-2G
409 # Default:
410  HistoryCacheSize=128M

412 ### Option: HistoryIndexCacheSize
413 #       Size of history index cache, in bytes.
414 #       Shared memory size for indexing history cache.
415 #
416 # Mandatory: no
417 # Range: 128K-2G
418 # Default:
419  HistoryIndexCacheSize=128M

421 ### Option: TrendCacheSize
422 #       Size of trend cache, in bytes.
423 #       Shared memory size for storing trends data.
424 #
425 # Mandatory: no
426 # Range: 128K-2G
427 # Default:
428  TrendCacheSize=128M

430 ### Option: ValueCacheSize
431 #       Size of history value cache, in bytes.
432 #       Shared memory size for caching item history data requests.
433 #       Setting to 0 disables value cache.
434 #
435 # Mandatory: no
436 # Range: 0,128K-64G
437 # Default:
438  ValueCacheSize=256M

440 ### Option: Timeout
441 #       Specifies how long we wait for agent, SNMP device or external check (in seconds).
442 #
443 # Mandatory: no
444 # Range: 1-30
445 # Default:
446  Timeout=30

　　其它參數保持默認值即可

　　如果需要監控VMware虛擬機，則還需要設置以下選項參數：

280 ### Option: StartVMwareCollectors
281 #       Number of pre-forked vmware collector instances.
282 #
283 # Mandatory: no
284 # Range: 0-250
285 # Default:
286  StartVMwareCollectors=2

304 ### Option: VMwareCacheSize
305 #       Size of VMware cache, in bytes.
306 #       Shared memory size for storing VMware data.
307 #       Only used if VMware collectors are started.
308 #
309 # Mandatory: no
310 # Range: 256K-2G
311 # Default:
312  VMwareCacheSize=256M

314 ### Option: VMwareTimeout
315 #       Specifies how many seconds vmware collector waits for response from VMware service.
316 #
317 # Mandatory: no
318 # Range: 1-300
319 # Default:
320  VMwareTimeout=300

16、配置 Apache 中的 PHP 參數（8GB 內存為例）

vim /etc/httpd/conf.d/zabbix.conf

php_value max_execution_time 600
php_value memory_limit 256M
php_value post_max_size 32M
php_value upload_max_filesize 32M
php_value max_input_time 600
php_value always_populate_raw_post_data -1
php_value date.timezone Asia/shanghai

17、重啟系統

systemctl stop mysqld && reboot

18、啟動 zabbix

systemctl start httpd && systemctl start zabbix-server

19、在瀏覽器中輸入 http://zbx監控服務器的IP地址/zabbix，進行 zabbix 的頁面初始化配置

這個頁面PHP設置要求全部OK

如果密碼輸錯，是跳轉不到下一步的。密碼是前面設置的 Abc@2018

注：第4步的”Zabbix server detail”頁面中，”Name”處可填寫對此監控系統的描述性文字，支持中文，有點像網站的名稱。

20、第一次登錄zbx監控系統，默認用戶名 admin，默認密碼 zabbix，確認可正常登錄系統。

21、登錄進入系統后，確認 Zabbix server is running 的值是 Yes。

然后選擇 Administrator –> Users –> Admin

22、回到”監測中” –> “儀表板”，就可以看到監控系統已設置為中文界面了。
