1. 配置mysql 主从模式 ​

安装Mysql 默认是8.0的版本；设置开机自启；启动Mysql

bash
apt install -y mysql-server
systemctl enable mysql
systemctl start mysql
systemctl status mysql

默认安装未设置root密码，登录设置密码

bash
mysql -uroot -p
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'qiaoke';
flush privileges;

主节点配置

bash
vim /etc/mysql/my.cnf

[mysqld]
server-id = 1          # 主服务器的唯一 ID
log_bin = mysql-bin    # 启用二进制日志
binlog_do_db = your_database_name  # 指定要复制的数据库（可选）
bind-address = 0.0.0.0

# 注释掉 /etc/mysql/mysql.conf.d/mysqld.cnf
bind-address            = 127.0.0.1

sudo systemctl restart mysql


# 创建复制用户
CREATE USER 'replication_user'@'%' IDENTIFIED BY 'zabbix';
GRANT REPLICATION SLAVE ON *.* TO 'replication_user'@'%';
ALTER USER 'replication_user'@'%' IDENTIFIED WITH mysql_native_password BY 'zabbix';
FLUSH PRIVILEGES;


# 获取二进制日志文件名和位置
FLUSH TABLES WITH READ LOCK;  -- 锁定表以确保数据一致性
SHOW MASTER STATUS;            -- 查看当前日志文件和位置

mysql-bin.000001 |      1342

从节点配置

vim /etc/mysql/my.cnf

[mysqld]
server-id = 2          # 从服务器的唯一 ID

sudo systemctl restart mysql

# 配置复制参数
CHANGE MASTER TO
    MASTER_HOST='192.168.116.150',
    MASTER_USER='replication_user',
    MASTER_PASSWORD='zabbix',
    MASTER_LOG_FILE='mysql-bin.000001',  -- 替换为主服务器的日志文件名
    MASTER_LOG_POS=881;                  -- 替换为主服务器的日志位置

START SLAVE;

# 查看复制状态
SHOW SLAVE STATUS\G;

创建zabbix 数据库

mysql -u root -p "qiaoke"
# 数据库
create database zabbix character set utf8mb4 collate utf8mb4_bin;
create user 'zabbix'@'%' identified by 'zabbix'; 
grant all privileges on zabbix.* to 'zabbix'@'%';
set global log_bin_trust_function_creators = 1;
flush privileges; 
quit

#将zabbix 数据库表 导入数据库
zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix

set global log_bin_trust_function_creators = 0;

1. zabbix server 高可用配置 ​

配置zabbix 软件源

bash
wget https://repo.zabbix.com/zabbix/6.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_latest+ubuntu22.04_all.deb
dpkg -i zabbix-release_latest+ubuntu22.04_all.deb
apt update

安装zabbix server, 前端组件，代理

bash
apt install zabbix-server-mysql zabbix-frontend-php zabbix-nginx-conf zabbix-sql-scripts zabbix-agent

配置Zabbix Server

bash
vim /etc/zabbix/zabbix_server.conf

# 修改以下内容
DBName=zabbix 
DBUser=zabbix
DBPassword=密码
DBHost=192.168.116.150
DBPort=3306

# 启动zabbix-server
systemctl enable zabbix-server 
systemctl restart zabbix-server
systemctl status zabbix-server

# 查看日志是否有报错
tail -f /var/log/zabbix/zabbix_server.log

高可用参数配置

vim /etc/zabbix/zabbix_server.conf

HANodeName=zabbix-ha1
NodeAddress=192.168.116.150:10051

HANodeName=zabbix-ha2
NodeAddress=192.168.116.151:10051

systemctl restart zabbix-server

2. 配置zabbix 前端页面 ​

配置nginx 监听

bash
vim  /etc/zabbix/nginx.conf 
# 将文件中的这两行注释去掉
listen 8080;
server_name example.com;

重启zabbix-server 并配置nginx php-fpm开机自启

bash
systemctl restart zabbix-server zabbix-agent nginx php8.1-fpm
systemctl enable nginx php8.1-fpm

4. 配置Nginx高可用 ​

在两个台节点安装 keepalived nginx

bash
apt install -y haproxy keepalived

配置zabbix-ha1 的keepalived

bash
vim /etc/keepalived/keepalived.conf

# 文件内容
global_defs {
    script_user root
    enable_script_security
}

vrrp_script chk_nginx {                   # 定义一个 vrrp_script，用于监控 nginx 进程
    script "/usr/bin/killall -0 nginx"                   # 监控 nginx 进程是否存在
    interval 2                             # 检测间隔（秒）
    weight 10                              # 如果检测失败，权重减少 10
}

vrrp_instance zabbix-ha1  { 
  state MASTER 
  interface ens33
  virtual_router_id 51 
  priority 244 
  advert_int 1 
  authentication {
    auth_type PASS 
    auth_pass 12345
  } 
  track_script { 
    chk_nginx
  }
  virtual_ipaddress {
    192.168.116.100/24
  }
}

配置zabbix-ha2 的keepalived

bash
vim /etc/keepalived/keepalived.conf

# 文件内容
global_defs {
    script_user root
    enable_script_security
}

vrrp_script chk_nginx {                   # 定义一个 vrrp_script，用于监控 nginx 进程
    script "/usr/bin/killall -0 nginx"                   # 监控 nginx 进程是否存在
    interval 2                             # 检测间隔（秒）
    weight 10                              # 如果检测失败，权重减少 10
}

vrrp_instance zabbix-ha2  { 
  state BACKUP 
  interface ens33 
  virtual_router_id 51 
  priority 243 
  advert_int 1 
  authentication {
    auth_type PASS 
    auth_pass 12345
  } 
  track_script { 
    chk_nginx
  }
  virtual_ipaddress {
    192.168.116.100/24
  }
}

验证

bash
# zabbix-ha1 执行
systemctl stop nginx

5. 配置zabbix proxy sqlite ​

配置zabbix proxy 源

bash
wget https://repo.zabbix.com/zabbix/6.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_latest+ubuntu22.04_all.deb
dpkg -i zabbix-release_latest+ubuntu22.04_all.deb
apt update

apt install zabbix-proxy-sqlite3

修改zabbix proxy 配置文件

bash
vim /etc/zabbix/zabbix_proxy.conf
