zabbix proxy 安装

zabbix proxy 4.0.x 安装

# 官方安装参考链接：
https://www.zabbix.com/download?zabbix=4.0&os_distribution=centos&os_version=7&components=proxy&db=mysql&ws=

# Install Zabbix repository
rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm
yum clean all

# Install Zabbix proxy
yum install zabbix-proxy-mysql -y

# 安装、初始化数据库。Zabbix-proxy也要连接一个数据库，一般安装在本地即可。
yum install -y mariadb*  # （其实只下载mariadb、mariadb-server、mariadb-devel也可）
systemctl start mariadb
systemctl enable mariadb

#mysql_secure_installation 设置mysql账户root密码

# 也可以直接设置mysql密码，mariadb 如果在本机是第一次安装，是没有密码滴，可以直接设置；如果在本机是再次安装，需要删除之前mysql的数据
/usr/bin/mysqladmin -u root password 'newpassword'

# Create initial database
mysql -uroot -p
newpassword
MariaDB [(none)]> create database zabbix_proxy character set utf8 collate utf8_bin;
MariaDB [(none)]> create user zabbix_proxy@localhost identified by 'zabbix_proxy';
MariaDB [(none)]> grant all privileges on zabbix_proxy.* to zabbix_proxy@localhost;
MariaDB [(none)]>  flush privileges;

# 导入 zabbix proxy 表结构
zcat /usr/share/doc/zabbix-proxy-mysql*/schema.sql.gz | mysql -uzabbix_proxy -p zabbix_proxy

/etc/zabbix/zabbix_proxy.conf
Server=127.0.0.1 # zabbix server IP地址

# zabbix 中的简单检查需要依赖 ping，所以需要配置fping命令
FpingLocation=/usr/sbin/fping

# 另外需要给 fping 配置 zabbix 用户的权限
[root@ip-10-250-0-214 zabbix]# whereis fping
