Zabbix

• 搭建环境说明

  A: 192.168.1.190, 系统CentOS 6.3,部署Zabbix Server, LEMP
  B: 192.168.1.191, 系统CentOS 6.3,部署Zabbix Agent, Nginx, MySQL, PHP, Redis, Memcached
  通过Zabbix Agent监控B机器的各项服务应用.

• Zabbix Server安装

  创建Zabbix运行的用户:

  # groupadd zabbix
  # useradd -g zabbix zabbix
  

  安装libcurl和net-snmp:

  # yum install net-snmp-devel curl-devel
  

  安装Fping:

  # wget -c http://fping.org/dist/fping-3.4.tar.gz
  # tar zxvf fping-3.4.tar.gz
  # cd fping-3.4
  # ./configure
  # make && make install
  # chown root:zabbix /usr/local/sbin/fping
  # chmod 4710 /usr/local/sbin/fping 
  

  安装Zabbix Server:

  # wget -c http://downloads.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/2.0.6/zabbix-2.0.6.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fzabbix%2F%3Fsource%3Ddlp&ts=1367916060&use_mirror=ncu
  # tar zxvf zabbix-2.0.6.tar.gz
  # cd zabbix-2.0.6
  # ./configure --prefix=/usr/local/zabbix --enable-server --enable-agent --with-mysql=/usr/local/mysql/bin/mysql_config --with-net-snmp --with-libcurl
  # make && make install
  

• Zabbix Server配置与启动

  创建Zabbix数据库和MySQL用户:

  mysql> create schema zabbix character set utf8;
  Query OK, 1 row affected (0.05 sec)
  
  mysql> create user 'zabbix'@'%' identified by '123456';
  Query OK, 0 rows affected (0.16 sec)
  
  mysql> grant all on zabbix.* to 'zabbix'@'%';
  Query OK, 0 rows affected (0.03 sec)
  
  mysql> flush privileges;
  Query OK, 0 rows affected (0.04 sec)
  

  导入Zabbix初始数据:

  # cd database/mysql/
  # mysql -uroot -p
  mysql> set sql_log_bin=0;
  mysql> source ./schema.sql;
  mysql> source ./images.sql;
  mysql> source ./data.sql;
  mysql> set sql_log_bin=1;
  

  编辑/usr/local/zabbix/etc/zabbix_server.conf:

  LogFile=/usr/local/zabbix/logs/zabbix_server.log
  PidFile=/usr/local/zabbix/logs/zabbix_server.pid
  DBHost=192.168.1.190
  DBName=zabbix
  DBUser=zabbix
  DBPassword=123456
  DBPort=3306
  FpingLocation=/usr/local/sbin/fping
  

  从安装目录拷贝zabbix_server脚本,并编辑:

  # cd zabbix-2.0.6
  # cp misc/init.d/Fedora/core5/zabbix_server /etc/init.d/
  # mkdir -p /usr/local/zabbix/logs
  # chown -R zabbix:zabbix /usr/local/zabbix
  # vi /etc/init.d/zabbix_server
  # cat /etc/init.d/zabbix_server
  

  ...
  ZABBIX_BIN="/usr/local/zabbix/sbin/zabbix_server"
  CONF_FILE="/usr/local/zabbix/etc/zabbix_server.conf"
  ...
  start() {
          ...
          daemon $ZABBIX_BIN -c $CONF_FILE
          ...
  }
  

  调整防火墙规则(开放端口10051):

  # vi /etc/sysconfig/iptables
  ...                                                                                                           
  -A INPUT -p tcp -m state --state NEW -m tcp --dport 10051 -j ACCEPT
  ...
  # /etc/init.d/iptables restart
  

  启动Zabbix Server:

  # service zabbix_server start
  Starting Zabbix Server:                                    [  OK  ]
  

  停止Zabbix Server:

  # service zabbix_server stop
  Stopping Zabbix Server:                                    [  OK  ]
  

  配置开机自动启动:

  # chkconfig --add zabbix_server
  # chkconfig --level 35 zabbix_server on
  

• Zabbix的Web前端

  在安装目录将frontends拷贝到指定的web root:

  # mkdir -p /data/www/zabbix
  # cd zabbix-2.0.6
  # cp -a frontends/php/* /data/www/zabbix/
  # chown -R www:www /data/www/zabbix
  

  Nginx配置:

  # cat /usr/local/nginx/conf/nginx.conf
  ...
  server {
      listen 80;
      server_name zabbix.zrwm.com;
      
      error_log logs/zabbix_error.log;
      access_log logs/zabbix_access.log;
  
      root /data/www/zabbix;
      index index.php index.html index.htm;
  
      location ~ \.php$ {
          fastcgi_pass   127.0.0.1:9000;
          fastcgi_index  index.php;
          fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
          include        fastcgi_params;
      }
  }
  ...
  

  php.ini配置:

  ...
  memory_limit = 128M
  post_max_size = 16M
  max_execution_time = 300
  max_input_time = 300
  session.auto_start = 0  ;必须为0
  mbstring.func_overload = 2
  ...
  

  注:PHP需要至少开启扩展:gd,bcmath,ctype,libXML,xmlreader,xmlwriter,session,sockets,mbstring,gettext,mysql

  访问Web界面http://zabbix.zrwm.com,进行相关web配置,配置完成后使用默认用户admin(密码:zabbix)登陆即可.
