zabbix学习1--zabbix6.x单机

1. 环境

进入官网查看所需部署环境配置以及应用版本要求https://www.zabbix.com/documentation/current/zh/manual/installation/requirements

2. MYSQL8.0

2.1 单节点

# 获取mysql
wget https://dev.mysql.com/get/mysql80-community-release-el7-7.noarch.rpm 
rpm -ivh mysql80-community-release-el7-7.noarch.rpm  
yum clean all;yum makecache# 安装mysql
yum install -y mysql-community-server mysql-community-devel \mysql-community-libs# 启动
systemctl start mysqld  
systemctl status mysqld  
systemctl enable mysqld  # 获取初始密码
cat /var/log/mysqld.log|grep password|rev|cut -d ':' -f1|rev|sed 's/ //g'         # 修改密码
# mysql -uroot -p
> alter user root@'localhost' identified by 'Honops@123';
> flush privileges;# 配置
systemctl stop mysqld 
1. 备份原配置cp /etc/my.cnf /etc/my.cnf.bk
2. 删除或mv原来最初数据rm /var/lib/mysql/* /var/log/mysqld.log -rf  
3. 创建路径mkdir -p /data/mysql/{install,data,log,run}chown -R mysql:mysql /data/mysql/{install,data,log,run}mkdir -p /data/mysql/log/{binlog,relaylog}chown mysql.mysql -R /data/mysql/log/{binlog,relaylog}
4. 创建配置文件，信息如【附录】，注意修改ip、id等
5. 初始化mysqld --initialize  --user=mysql 
6. 启动mysqlsystemctl start mysqld  systemctl status mysqld  
7. 获取初始密码/修改默认密码
【获取初始密码如上；日志文件：/data/mysql/log/mysqld.log】mysql  -uroot --socket=/data/mysql/run/mysql.socket -p> alter user root@'localhost' identified by 'Honops@123';> CREATE USER 'root'@'192.168.20.61' IDENTIFIED BY 'Honops@123'; > GRANT all PRIVILEGES on *.* to 'root'@'192.168.20.61';      > flush privileges;给予grant_priv（GRANT OPTION）权限
> select user,host,grant_priv from mysql.user where user="root";
> update  mysql.user set grant_priv="Y"  where user="root" and host="192.168.20.61";
> flush privileges;

2.2 配置主从

配置主从 
master主机执行
> CREATE USER 'repl'@'%' IDENTIFIED BY 'Slave123'; 
> GRANT REPLICATION SLAVE ON *.* TO 'repl'@'%';
> ALTER USER 'repl'@'%' IDENTIFIED WITH mysql_native_password BY 'Slave123';
> flush privileges;
> show master status;
slave主机执行
> change master to master_host='master主机ip',master_user='repl',-> master_password='Slave123', master_log_file='xxxx.xxxx',-> master_log_pos=xxxxx;
> start slave;
> show slave status\G

配置并下一步

Zabbix图形会出现无法显示中文字体的情况 ：windows的字体路径C:\Windows\Fonts  随便【中文】字体
替换  /data/zabbix/php/assets/fonts/DejaVuSans.ttf  名称保留DejaVuSans
