Linux 安装Zabbix 3.4

01、配置与前提

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

　　00.2、安装vim编辑器 yum -y install vim 

　　00.3、zabbix 客户端安装 https://www.cnblogs.com/huanu/p/9253777.html 

02、关闭SELinux

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

03、关闭防火墙

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

　　完成03、04后，用reboot命令重启一下操作系统，并重新登录

04、获取SQL源

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

05、安装 Zabbix 所需软件支持包

　　先安装mysql

yum -y install mysql-* --skip-broken #有冲突的软件跳过

　　安装Apache

yum -y install httpd

systemctl start httpd.service #启动
systemctl stop httpd.service #停止
systemctl restart httpd.service #重启
systemctl enable httpd.service #开机启动
systemctl disable httpd.service #开机不启动

　　安装php

yum -y install php

　　安装php扩展

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、设置 MySQL 参数（8GB 内存为例）

vim /etc/my.cnf  #不然没权限保存

　　在my.cnf后面添加以下内容

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：原则上 innodb_buffer_pool_size 需要设置为主机内存的 80%，如果主机内存不是 8GB，以上参数可依据相应比例进行调整，例如主机内存为 16GB，则 innodb_buffer_pool_size 建议设置为 12GB，innodb_log_buffer_size 建议设置为 32M，innodb_log_file_size 建议设置为 128M，以此类推。请注意innodb_buffer_pool_size的值必须是整数，例如主机内存是4G，那么innodb_buffer_pool_size可以设置为3G，而不能设置为3.2G

07、启动MySQL

systemctl enable mysqld && systemctl start mysqld

08、获取 MySQL 的 root 初始密码

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. #即是默认mysql密码

09、进行 MySQL 安全配置
　　配置开始时会用到第 09获取的初始密码，建议修改为自定义密码，其它选项选择 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:

　　密码改为：Abc2345,.

10、重启 MySQL

systemctl restart mysqld

11、配置 MySQL 中 zabbix要的库和账号权限

[root@localhost ~]# mysql -u root -p（需要输入第 10步中设置的自定义密码）

mysql>create database zabbix character set utf8; #创建数据库
mysql>create user zabbix@'%' identified by 'Abc@2018'; #创建用户和密码
mysql>grant all privileges on zabbix.* to zabbix@'%'; #赋权
mysql>flush privileges;
mysql>exit;

12、安装 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、安装zabbix

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

14、导入 zabbix 所需信息

cd /usr/share/doc/zabbix-server-mysql-3.4  #先按Tab键补全文件夹全名
zcat create.sql.gz | mysql -uroot zabbix -p  #（需要输入第 10 步中设置的自定义密码）

15、配置 zabbix 参数

vim /etc/zabbix/zabbix_server.conf #这个配置要一遍过

　　主要是以下几个选项参数需要设置（8GB 内存为例）：

　　vim显示行号命令 ：set number 

119 ### Option: DBPassword
120 #       Database password. Ignored for SQLite.
121 #       Comment this line if no password is used.

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.

442 #
443 # Mandatory: no
444 # Range: 1-30
445 # Default:
446  Timeout=30

　　其它参数保持默认值即可

　　如果需要监控VMware虚拟机，则还需要设置以下选项参数：

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 #

316 #
317 # Mandatory: no
318 # Range: 1-300
319 # Default:
320  VMwareTimeout=300

16、配置 Apache 中的 PHP 参数（8GB 内存为例）

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、重启系统

systemctl stop mysqld && reboot

18、启动 zabbix

systemctl start httpd && systemctl start zabbix-server

19、在浏览器中输入 http://zbx监控服务器的IP地址/zabbix，进行 zabbix 的页面初始化配置

这个页面PHP设置要求全部OK

如果密码输错，是跳转不到下一步的。密码是前面设置的 Abc@2018

注：第4步的”Zabbix server detail”页面中，”Name”处可填写对此监控系统的描述性文字，支持中文，有点像网站的名称。

20、第一次登录zbx监控系统，默认用户名 admin，默认密码 zabbix，确认可正常登录系统。

21、登录进入系统后，确认 Zabbix server is running 的值是 Yes。

然后选择 Administrator –> Users –> Admin

22、回到”监测中” –> “仪表板”，就可以看到监控系统已设置为中文界面了。
