前言：
而今你们对“mysql授权网段”大体比较注意，朋友们都想要剖析一些“mysql授权网段”的相关文章。那么小编同时在网络上收集了一些对于“mysql授权网段””的相关知识，希望朋友们能喜欢，同学们一起来了解一下吧！准备机子和环境

zabbix自动发现
在一台机器(例10.3.145.65) 部署zabbix-server，实现监控。 其他机器均须部署 zabbix-agent （10.3.145.39、10.3.145.64、10.3.145.63）
安装zabbix-server
## 安装zabbix源（官方）（四台机子都进行配置）[root@10v3v145v65 roles]#rpm -ivh ## 而后更新我们的yum仓库：[root@10v3v145v65 roles]# yum repolist ## 安装[root@10v3v145v65 ~]# yum -y install zabbix-agent zabbix-get zabbix-sender zabbix-server-mysql zabbix-web zabbix-web-mysql
## 1.创建 mariadb.repo[root@10v3v145v65 roles]# vim /etc/yum.repos.d/mariadb.repo[mariadb]name = MariaDB baseurl = gpgkey= gpgcheck=12.下载安装[root@10v3v145v65 roles]# yum -y install MariaDB-server MariaDB-client3.首先，我们修改一下配置文件——/etc/my.cnf.d/server.cnf [root@10v3v145v65 roles]#vim /etc/my.cnf.d/server.cnf [mysqld] skip_name_resolve = ON #跳过主机名解析 innodb_file_per_table = ON # innodb_buffer_pool_size = 256M #缓存池大小 max_connections = 2000 #最大连接数 log-bin = master-log #开启二进制日志4.重启我们的数据库服务[root@10v3v145v65 roles]# systemctl restart mariadb[root@10v3v145v65 roles]# mysql_secure_installation #初始化mariadb5.登录数据库#mysqlMariaDB [(none)]> create database zabbix character set 'utf8'; # 创建zabbix数据库MariaDB [(none)]> grant all on zabbix.* to 'zbxuser'@'10.3.145.%' identified by 'keer'; # 注意授权网段MariaDB [(none)]> flush privileges; # 刷新授权6.导入表首先，我们来查看一下，`zabbix-server-mysql`这个包提供了什么/usr/share/doc/zabbix-server-mysql-4.0.9/create.sql.gz #生成表的各种脚本 #gzip -d create.sql.gz #head create.sql #查看内容 vim /usr/share/doc/zabbix-server-mysql-4.0.9/create.sql USER zabbix #如果缺少，第一行添加 7.导入数据 cd /usr/share/doc/zabbix-server-mysql-4.0.9/[root@10v3v145v65 zabbix-server-mysql-4.0.9]# mysql -uzbxuser -h10.3.145.65 -p zabbix < create.sql 8.修改配置文件 cd /etc/zabbix/ cp zabbix_server.conf{,.bak} #为了可以反悔，cp一份 vim zabbix_server.conf #修改后配置如下ListenPort=10051 #默认监听端口SourceIP=10.3.145.65 #发采样数据请求的IP（本机）DBHost=10.3.145.65 #数据库对外的主机DBName=zabbix #数据库名称DBUser=zbxuser #数据库用户DBPassword=keer #数据库密码DBPort=3306 #数据库启动端口9.开启服务#systemctl start zabbix-server.service#ss -nutl |grep 10051tcp LISTEN 0 128 *:10051 *:* tcp LISTEN 0 128 :::10051 :::* Alias /zabbix /usr/share/zabbix #我们访问的时候要在主机后加上/zabbix来访问我们这个服务#vim /etc/php.ini #配置时区 [Date] ; Defines the default timezone used by the date functions ; date.timezone = Asia/Shanghai 10.接下来，我们就可以启动我们的`httpd`服务了：[root@10v3v145v65 zabbix]# systemctl restart httpd.service ## 访问 10.3.145.65/zabbix## 进行初始化配置ansible安装zabbix-agent
## 添加ansibled的hosts解析[root@10v3v145v65 ~]# vim /etc/ansible/hosts[zabbix-agent]10.3.145.3910.3.145.6410.3.145.63## 写剧本---创建以下目录[root@10v3v145v65 roles]# tree ..├── site.yaml└── zabbix-agent ├── files ├── handlers │ └── main.yaml ├── tasks │ └── main.yaml └── templates └── zabbix_agentd.conf.j2[root@10v3v145v65 ~]# mkdir /data/roles/zabbix-agent/{files,handlers,tasks,templates} -p[root@10v3v145v65 ~]# cd /data/roles/zabbix-agent[root@10v3v145v65 roles]# vim ../site.yaml - hosts: zabbix-agent roles: - zabbix-agent[root@10v3v145v65 zabbix-agent]# vim handlers/main.yaml---- name: restart zabbix-agent service: name=zabbix-agent state=restarted[root@10v3v145v65 zabbix-agent]# vim tasks/main.yaml---- name: install zabbix-agent packge yum: name=zabbix-agent state=present- name: copy zabbix-agent.conf template template: src=zabbix_agentd.conf.j2 dest=/etc/zabbix/zabbix_agentd.conf notify: restart zabbix-agent- name: make sure zabbix-agent service running service: name=zabbix-agent state=started enabled=yes[root@10v3v145v65 zabbix-agent]# cp /etc/zabbix/zabbix_agentd.conf ./templates/zabbix_agentd.conf.j2## 编写配置文件[root@10v3v145v65 zabbix-agent]# vim templates/zabbix_agentd.conf.j2Server=192.168.195.139///服务的IP ServerActive=192.169.195.139///服务的IPHostname=192v168v195v139///服务的hostname## 修改这三项即可 ##[root@10v3v145v65 zabbix-agent]# ansible-playbook ./site.yaml --syntax-check //检查语法[root@10v3v145v65 zabbix-agent]# ansible-playbook ./site.yaml //实施剧本配置自动发现一、创建发现规则
