zabbix安装注意

在Linux下安装zabbix注意的几点

1.mysql授权后查看用户权限

   show grants for 'zabbix'@'localhost';

2.新建用户

   useradd -M -s /sbin/nologin zabbix  //新建zabbix用户，无主目录，不可登陆

3.编译zabbix出错

  mysql library not found->find / -name "mysql_config"->--with-mysql=/..
  invaild net-snmp->yum install net-snmp-devel
  error while loading share libraries->find / -name libnetsnmp.so.30->该位置添加到/etc/ld.so.conf->ldconfig

4.zabbix_server启动报错
  can't connect to local mysql server through socket ->在zabbix_server.conf修改DBSocket=/tmp/mysql.sock

5.网页打开zabbix返回500错误
  tail -f /var/log/httpd/error_log->permission denied in权限问题-> chown apache.apache -R /var/www/html/zabbix
                                                    ->php解析错误 php版本过低需要升级

6.php版本升级
  yum remove php php-bcmath php-cli php-common php-devel php-fpm 
  php-gd php-imap php-ldap php-mbstring php-mcrypt php-mysql  php-odbc  php-pdo  php-pear php-pecl-igbinary php-xml php-xmlrpc
  rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
  yum install php54w php54w-bcmath php54w-cli php54w-common php54w-devel php54w-fpm  php54w-gd php54w-imap php54w-ldap php54w-mbstring php54w-mcrypt php54w-mysql  php54w-odbc  php54w-pdo  php54w-pear php54w-pecl-igbinary php54w-xml php54w-xmlrpc php54w-opcache php54w-intl php54w-pecl-memcache

7.缺失libxpm.so.4
  yum whatprovides libXpm.so.4
  yum install ...
  find / -name "libXpm.so.4"->包含lib和lib64都有库文件，没有安装 x86_64/i686

8.php连接mysql报错 can't mysql throut mysql socket /var/lib/mysql/mysql.sock 
  ps -ef|grep mysql查看mysql.sock位置
  ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock
  vi php.ini-> mysql.default_socket=/tmp/mysql.sock

9.zabbix server is not running  主机为localhost
  selinux set setenforce 0
  iptables stop
  vim /web/zabbix/conf/zabbix.conf.php->$ZBX_SERVER='192.168.30.6'
  service httpd restart
  /etc/init.d/zabbix_server start

10.zabbix安装聚合图形的补丁
  cd /var/www/html/zabbix
  wget https://raw.githubusercontent.com/OneOaaS/graphtrees/master/graphtree3-0-1.patch
  patch -Np0 < graphtree3-0-1.patch
  查看oneoaas 的所有者 apache.apache
  查看include目录下 func.inc.php menu.inc.php 的所有者 apache.apache 

11.在关闭MySQL服务时，无法关闭的情况，可以杀死进程
   pkill -9 mysqld_safe
   pkill -9 mysqld
   service mysqld start或者 mysql../bin/mysqld_safe --user=mysql

12.查看mysql连接socket
   ps -ef|grep mysql
   show variables like 'socket';
