• aws上部署zabbix3.4


    三台机器

    10.0.0.149  AmazonLinux2.0  zabbix-server zabbix-agent
    10.0.1.61   CentOS6.9       zabbix-agent
    10.0.1.119  CentOS6.9       zabbix-agent
    

    1、安装zabbix-server和web管理界面。

    # cd /etc/yum.repos.d/
    # vim zabbix.repo
    [zabbix]
    name=zabbix3.4
    baseurl=http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/
    gpgcheck=0
    
    # vim epel.repo
    [epel]
    name=epel-release
    baseurl=https://dl.fedoraproject.org/pub/epel/7/x86_64/
    gpgcheck=0
    
    # yum install -y zabbix-server-mysql zabbix-web-mysql
    

    2、安装配置数据库并启动zabbix-server。

    # yum install -y mariadb-server mariadb mariadb-devel
    
    # vim /etc/my.cnf
    [mysqld]
    datadir=/var/lib/mysql
    socket=/var/lib/mysql/mysql.sock
    max_connect_errors=1000
    skip_name_resolve
    innodb_file_per_table=1
    skip-external-locking
    key_buffer_size = 16M
    default-storage-engine=innodb
    collation_server=utf8_unicode_ci
    character_set_server=utf8
    max_connections=3000
    wait_timeout=600
    tmp_table_size=500M
    innodb_buffer_pool_size = 100M
    innodb_log_file_size=700M
    innodb_log_buffer_size=8M
    query_cache_size = 256M
    query_cache_type = 1
    query_cache_limit = 1048576
    join_buffer_size = 8M
    thread_cache_size = 80
    innodb_support_xa = 1
    long_query_time = 2
    slow-query-log = 1
    slow-query-log-file=/var/log/mariadb/slowquery.log
    max_allowed_packet = 1M
    table_open_cache = 64
    sort_buffer_size = 16M
    net_buffer_length = 8K
    read_buffer_size =8M
    read_rnd_buffer_size = 512K
    myisam_sort_buffer_size = 8M
    
    # systemctl start mariadb.service
    # systemctl enable mariadb.service
    
    # mysql_secure_installation
    # mysql -uroot -p
    > create database zabbix character set utf8 collate utf8_bin;
    > grant all privileges on zabbix.* to zabbix@localhost identified by 'PASS';
    > quit;
    
    # cd /usr/share/doc/zabbix-server-mysql-3.4.7/
    # zcat create.sql.gz | mysql -uroot zabbix -p
    
    # vim /etc/zabbix/zabbix_server.conf
    DBHost=localhost
    DBName=zabbix
    DBUser=zabbix
    DBPassword=PASS
    
    # systemctl start zabbix-server.service
    # systemctl enable zabbix-server.service
    

    3、httpd会被依赖安装。修改php时区,并启动httpd。

    # vim /etc/php.ini
    [Date]
    date.timezone = Asia/Shanghai
    
    # vim /etc/httpd/conf.d/zabbix.conf
    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 always_populate_raw_post_data -1
    # php_value date.timezone Europe/Riga
    php_value date.timezone Asia/Shanghai
    
    # systemctl start httpd.service
    # systemctl enable httpd.service
    

    4、设置域名。配置nginx。

    在dns上加一条CNAME指向LB即可。

    # cd /etc/nginx/vhosts/
    # vim zabbix-aws.oupeng.com.conf
    upstream zabbix-aws-oupeng-com {
        server 10.0.0.149:80 weight=10 max_fails=3 fail_timeout=10;
    }
    
    server {
        listen 80;
        server_name zabbix-aws.oupeng.com;
    
        location / {
            proxy_pass http://zabbix-aws-oupeng-com/zabbix/;
            include proxy.conf;
            break;
        }
    
        access_log /data/log/nginx/zabbix-aws.oupeng.com.access.log main;
        error_log /data/log/nginx/zabbix-aws.oupeng.com.error.log;
    }
    

    5、访问web界面,完成初始化。

    默认用户密码为 Admin/zabbix。需要注意的是,这里的用户名区分大小写。

    6、安装zabbix-agent。

    # yum install -y zabbix-agent
    
    # systemctl start zabbix-agent.service
    # systemctl enable zabbix-agent.service
    

    在另外两台机器上安装客户端。由于系统版本不同,这里要单独添加repo。

    # cd /etc/yum.repos.d/
    # vim zabbix.repo
    [zabbix]
    name=zabbix3.4
    baseurl=http://repo.zabbix.com/zabbix/3.4/rhel/6/x86_64/
    gpgcheck=0
    
    # yum install -y zabbix-agent
    

    修改监听地址,并启动服务。

    # vim /etc/zabbix/zabbix_agentd.conf
    Server=10.0.0.149
    
    # service zabbix-agent start
    # chkconfig zabbix-agent on
    

    7、到这里,基础安装就完成了。在web上添加三台主机就可以开始设置监控了。


    补充

    8、设置数据库备份,保留三天备份。

    # vim mysql_backup.sh
    #!/bin/bash
    
    basepath='/data/mysql/backup/'
    
    if [ ! -d "$basepath" ]; then
      mkdir -p "$basepath"
    fi
    
    #backup
    mysqldump -uroot -p'PASS' -F -A | gzip > $basepath/mysqlbak_$(date +%F).sql.gz
    
    #delete files 3 days ago
    find $basepath -mtime +3 -name "*.sql.gz" -exec rm -rf {} ; >/dev/null 2>&1
    
    # crontab -e
    0 0 * * * /root/mysql_backup.sh
