  • 2.监控软件zabbix-服务端安装

    环境准备

    Zabbix服务端环境要求:

    Red Hat Enterprise Linux
    CentOS
    Oracle Linux
    Debian
    Ubuntu

    注意,要安装的Zabbix服务器需要联网,如果没有网络以下内容不适用.

    软件准备

    Zabbix服务端安装包

    Zabbix官网镜像:http://repo.zabbix.com/zabbix/2.4/

    阿里云镜像:http://mirrors.aliyun.com/zabbix/zabbix/2.4/

    关联软件安装包

    数据库

    Zabbix-Server支持的数据库:

    MySQL

    Oracle

    SQLite

    IBM DB2

    PostgreSQL

    我们这里选用的是MySQL,MySQL的资源位置:

    http://dev.mysql.com/downloads/file.php?id=450542

    前端展示

    Apache

    PHP

    客户端的浏览器必须要开启JavaScript和Cookies

    服务端
    软件需求 描述
    OpenIPMI 需要支持IPMI
    libssh2 需要支持SSH服务,大于1.0版本
    fping ICMP的ping命令需要
    libcurl 服务端监听需要
    libiksemel Jabber支持需要
    net-snmp SNMP支持需要
    版本要求

    相关软件的版本需参考官方文档中的描述:

    https://www.zabbix.com/documentation/2.4/manual/installation/requirements

    将2.4更换为相应版本号即可。

    安装过程

    安装Yum源

    [root@localhost zabbix]# rpm -ivh http://mirrors.aliyun.com/zabbix/zabbix/2.4/rhel/6/i386/zabbix-release-2.4-1.el6.noarch.rpm
    [root@localhost zabbix]# rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
    [root@localhost zabbix]# rpm -ivh http://dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm

    安装软件包

    [root@localhost zabbix]# yum install -y zabbix zabbix-get zabbix-server zabbix-web-mysql zabbix-web zabbix-server-mysql mysql-server

    到此我们Zabbix-Server端软件已经安装完毕.

    软件配置

    MySQL的配置

    [root@localhost mysql]# vi /etc/my.cnf
    # For advice on how to change settings please see
    # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
    
    [mysqld]
    #
    # Remove leading # and set to the amount of RAM for the most important data
    # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
    # innodb_buffer_pool_size = 128M
    #
    # Remove leading # to turn on a very important data integrity option: logging
    # changes to the binary log between backups.
    # log_bin
    #
    # Remove leading # to set options mainly useful for reporting servers.
    # The server defaults are faster for transactions and fast SELECTs.
    # Adjust sizes as needed, experiment to find the optimal values.
    # join_buffer_size = 128M
    # sort_buffer_size = 2M
    # read_rnd_buffer_size = 2M
    datadir=/var/lib/mysql
    socket=/var/lib/mysql/mysql.sock
    user=mysql
    # Disabling symbolic-links is recommended to prevent assorted security risks
    symbolic-links=0
    
    # Recommended in standard MySQL setup
    sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
    
    character-set-server=utf8 #设置字符集为utf8
    innodb_file_per_table=1 #让innodb的每个表文件单独存储
    
    [mysqld_safe]
    log-error=/var/log/mysqld.log
    pid-file=/var/run/mysqld/mysqld.pid

    启动MySQL

    [root@localhost mysql]# service mysqld start

    修改root用户密码

    [root@localhost mysql]# mysqladmin -uroot password root

    创建Zabbix数据库以及用户

    [root@localhost mysql]# mysql -uroot -proot
    Warning: Using a password on the command line interface can be insecure.

    Bye
    [root@localhost mysql]#

    导入Zabbix-Server表结构和数据

    [root@localhost mysql]# mysql -uzabbix -pzabbix
    Warning: Using a password on the command line interface can be insecure.

    mysql> source /usr/share/doc/zabbix-server-mysql-2.4.6/create/data.sql;

    Zabbix-Server的配置

    Zabbix-Server端默认情况下只需要修改连接MySQL数据库的密码即可(其它参数可根据实际环境需求修改):

    修改内容:

    [root@localhost zabbix]# egrep -v "(^#|^$)" /etc/zabbix/zabbix_server.conf
    LogFile=/var/log/zabbix/zabbix_server.log
    LogFileSize=0
    PidFile=/var/run/zabbix/zabbix_server.pid
    DBName=zabbix
    DBUser=zabbix
    DBPassword=zabbix
    DBSocket=/var/lib/mysql/mysql.sock
    SNMPTrapperFile=/var/log/snmptt/snmptt.log
    AlertScriptsPath=/usr/lib/zabbix/alertscripts
    ExternalScripts=/usr/lib/zabbix/externalscripts

    创建扩展脚本路径:

    [root@localhost zabbix]# mkdir /etc/zabbix/alertscripts /etc/zabbix/externalscripts

    httpd的配置

    要这是前端展示的字符集和时区信息

    [root@localhost conf.d]# vi zabbix.conf
    <Directory "/usr/share/zabbix">
        Options FollowSymLinks
        AllowOverride None
        Order allow,deny
        Allow from all
    
        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 data.timezone Asia/Shanghai
        # php_value date.timezone Europe/Riga
    </Directory>

    服务启动

    [root@localhost create]# service zabbix-server start
    [root@localhost create]# service httpd start

    配置开机启动

    [root@localhost create]# chkconfig mysqld on
    [root@localhost create]# chkconfig zabbix-server on
    [root@localhost create]# chkconfig httpd on

    检查验证

    登录验证

    http://192.168.80.210/zabbix/setup.php

    进入设置页面

    1、设置主页

    image

    2、PHP相关参数检查

    image

    3、数据库连接配置,要注意进行验证连接是否可用

    image

    4、Zabbix-Server端详细信息

    image

    5、安装详情

    image

    6、完成安装

    image

    如果此步骤写入文件失败,可以尝试关闭SELINUX

    [root@localhost conf.d]# vi /etc/selinux/config
    SELINUX=disabled

    然后重启启动Linux服务器

    7、点击finish即可进入主页,默认用户名:admin 密码:zabbix

    8、进入页面如下结果

    常见问题:

    1、添加完防火墙过滤规则后,执行service iptables restart出错(Center OS 7),如下所示:

    [root@localhost sysconfig]# service iptables restart
    Redirecting to /bin/systemctl restart  iptables.service
    Failed to issue method call: Unit iptables.service failed to load: No such file or directory.
    [root@localhost sysconfig]#

    主要是因为没有安装iptables service导致的,所以当修改防火墙设置后,重启该服务无效。在Center OS7 或RHEL7 中防火墙引入进来管理iptables,在IMHO中,对于服务器环境而言,防火墙比工作站更安全、可靠。

    所以可以通过如下办法解决:

    [root@localhost sysconfig]# systemctl stop firewalld 
    [root@localhost sysconfig]# systemctl mask firewalld 
    ln -s '/dev/null' '/etc/systemd/system/firewalld.service'
    [root@localhost sysconfig]# yum install iptables-services

    完毕!
    [root@localhost sysconfig]# systemctl start iptables
    [root@localhost sysconfig]# service iptables restart
    Redirecting to /bin/systemctl restart  iptables.service
    [root@localhost sysconfig]# service iptables save

    参考网址:http://stackoverflow.com/questions/24756240/how-can-i-use-iptables-on-centos-7

    2、防火墙配置问题

    如果连接不上80或者10051或者10050,需在/etc/sysconfig/iptables中添过滤规则:

    [root@localhost create]# vi /etc/sysconfig/iptables
    
    # Firewall configuration written by system-config-firewall
    # Manual customization of this file is not recommended.
    *filter
    :INPUT ACCEPT [0:0]
    :FORWARD ACCEPT [0:0]
    :OUTPUT ACCEPT [0:0]
    -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
    -A INPUT -p icmp -j ACCEPT
    -A INPUT -i lo -j ACCEPT
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
    -A INPUT -j REJECT --reject-with icmp-host-prohibited
    -A FORWARD -j REJECT --reject-with icmp-host-prohibited
    
    # http
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
    # zabbix-server
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 10051 -j ACCEPT
    # zabbix-agent
    -A OUTPUT -m state --state NEW -m tcp -p tcp --dport 10050 -j ACCEPT
    -A INPUT -m state --state NEW -m tcp -p tcp --sport 10050 -j ACCEPT
    COMMIT
     
    [root@localhost create]# service iptables restart

    如果还有问题,可以用如下命令尝试刷新路由表:

    [root@localhost ~]# iptables -F

    3、如果设置/etc/httpd/conf.d/zabbix.conf的timezone只不起作用

    可以进行如下尝试

    [root@localhost conf.d]# service httpd restart

    如果依然存在问题,则进行如下操作:

    [root@localhost conf.d]# vi /etc/php.ini
    [Date]
    ; Defines the default timezone used by the date functions
    ; http://www.php.net/manual/en/datetime.configuration.php#ini.date.timezone
    date.timezone = Asia/Shanghai
