CentOS 7.8 x64 安裝zabbix 5.0 LTS

官網教程

• https://www.zabbix.com/download?zabbix=5.0&os_distribution=centos&os_version=7&db=mysql&ws=nginx
  

手把手安裝教程

1. 安裝zabbix庫

   • $ rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm	
     $ yum clean all	【清除yum快取】
     

2. 安裝zabbix server 和 agent

   • $ yum install zabbix-server-mysql zabbix-agent
     【後面出現的互動確認 全部選擇Y】
     

3. 安裝zabbix前端

   • $ yum install centos-release-scl	【安裝前端release】
     

   • $ vi /etc/yum.repos.d/zabbix.repo
     【修改配置】
     	...
     	enabled=1
     	...
     

4. 安裝mysql資料庫

   • 本次mysql安裝我們選擇rpm安裝方式，安裝的mysql版本為5.7.30

   1. 下載mysql 5.7.30 rpm包

      • wget -i -c http://dev.mysql.com/get/mysql-5.7.30-1.el7.x86_64.rpm-bundle.tar

   2. 解壓

      • tar -xvf mysql-5.7.30-1.el7.x86_64.rpm-bundle.tar

   3. 檢視系統裡是否已經有安裝過mysql，有則解除安裝

      • rpm -qa|grep mariadb 【檢視】
      • rpm -e --nodeps mariadb-libs-5.5.65-1.el7.x86_64【解除安裝】

   4. 安裝mysql5.7所需要的依賴

      • yum install libaio
      • yum install perl
      • yum install net-tools

   5. 安裝mysql

      • rpm -ivh mysql-community-common-5.7.30-1.el7.x86_64.rpm
      • rpm -ivh mysql-community-libs-5.7.30-1.el7.x86_64.rpm
      • rpm -ivh mysql-community-libs-compat-5.7.30-1.el7.x86_64.rpm
      • rpm -ivh mysql-community-client-5.7.30-1.el7.x86_64.rpm
      • rpm -ivh mysql-community-server-5.7.30-1.el7.x86_64.rpm

   6. 配置mysql資料庫

      • 啟動mysql

        • systemctl start mysqld.service

      • 檢視mysql執行狀態

        • systemctl status mysqld.service

      • 找到root初始密碼

        • grep "password" /var/log/mysqld.log

      • 修改root密碼

        • ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password';

      • 開啟mysql的遠端訪問【下面命令開啟的IP是 192.168.0.1，如要開啟所有的，用%代替IP】

        • grant all privileges on . to 'root'@'192.168.0.1' identified by 'password' with grant option;
        • flush privileges;
        • exit

      • 為firewalld新增開放埠【新增mysql埠3306和Tomcat埠8080】

        • firewall-cmd --zone=public --add-port=3306/tcp --permanent
        • firewall-cmd --zone=public --add-port=8080/tcp --permanent
        • 或者選擇吧firewalld服務臨時關閉【service firewalld stop】

      • 修改字符集

        • 描述【重新登入mysql，然後輸入status，經過觀察，不難發現裡面有兩個不是utf-8】

        • 改為utf-8方法：

          • vi /etc/my.cnf

          • 新增下列四行
            [client]
            default-character-set=utf8
            
            character-set-server=utf8
            collation-server=utf8_general_ci
            

          • 實現的效果如下所示：
            ​```
            [client]
            default-character-set=utf8
            # For advice on how to change settings please see
            # http://dev.mysql.com/doc/refman/5.7/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
            character-set-server=utf8
            collation-server=utf8_general_ci
            # Disabling symbolic-links is recommended to prevent assorted security risks
            symbolic-links=0
             
            log-error=/var/log/mysqld.log
            pid-file=/var/run/mysqld/mysqld.pid
            ​```
            

          • 重啟mysqld 服務

   7. 初始化zabbix的資料庫

      • note：

        • mysql口令：root abcD_123
          zabbix口令：zabbix abcD_123
          

      • mysql> create database zabbix character set utf8 collate utf8_bin; 【修改字符集】

      • mysql> create user zabbix@localhost identified by 'password';【建立使用者zabbix和密碼】

      • mysql> grant all privileges on zabbix.* to zabbix@localhost;【授權登入】

      • mysql> quit;

      • $ zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix 【匯入初始化的schema和資料】
        

   8. zabbix server配置

      • $ vi /etc/zabbix/zabbix_server.conf
        DBPassword=password【將資料庫password填入】
        

   9. zabbx前端php配置

      • $ vi /etc/opt/rh/rh-nginx116/nginx/conf.d/zabbix.conf
        【解開註釋】
        # listen 80;
        # server_name example.com;
        

      • $ vi /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf
        【修改為】
        listen.acl_users = apache,nginx
        
        【解開註釋】
        php_value[date.timezone] = Asia/Shanghai
        
        

   10. 啟動zabbix server and agent 程序

       • $ systemctl restart zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm
         $ systemctl enable zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm
         

   11. 登入zabbix

       • 官方quick start：https://www.zabbix.com/documentation/5.0/manual/quickstart/login
       • 預設密碼是Admin/zabbix

   12. 安裝完成後遇到的問題

       • 問題描述：登入zabbix前端，發現介面下方一直有報錯，報錯釋義”zabbix server啟動失敗“

       • 檢視日誌：/var/log/zabbix/zabbix_server.log , 發現無法繫結socket到zabbix_server_alerter.sock，訪問被拒絕

       • 原因：selinux問題

       • 解決方法：關閉selunx

         • $ sestatus【檢視selinux狀態】
           $ vi /etc/selinux/config
           【配置修改如下】
           ...
           SELINUX=disabled
           ...
           SELINUXTYPE=targeted 
           
           $ reboot 【修改配置檔案，重啟永久關閉】
           或者 $ setenforce 0【臨時關閉】
