搭建双主zabbix
架构图
环境准备
操作系统：Ubuntu1804，zabbix4.0
172.31.1.30 zabbix-server1 rsync + inotify-tools
172.31.1.31 zabbix-server2 rsync + inotify-tools
172.31.1.32 mysql-server1
172.31.1.33 mysql-server2
172.31.1.34 keepalived + haproxy1
172.31.1.35 keepalived + haproxy2
安装haproxy和keepalived（两台都要）
[root@zabbix-ha1 ~]# apt -y install haproxy keepalived
查找模板
[root@zabbix-ha1 ~]# find / -name "*keepalived.conf*"
拷贝模板
[root@zabbix-ha1 ~]# cp /usr/share/doc/keepalived/samples/keepalived.conf.vrrp /etc/keepalived/keepalived.conf
配置keepalived
[root@zabbix-ha1 ~]# cat /etc/keepalived/keepalived.conf
! Configuration File for keepalived
global_defs {
notification_email {
acassen
}
notification_email_from Alexandre.Cassen@firewall.loc
smtp_server 192.168.200.1
smtp_connect_timeout 30
router_id LVS_DEVEL
}
vrrp_instance apache {
state MASTER
interface eth0
garp_master_delay 10
smtp_alert
virtual_router_id 55
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
172.31.1.100 dev eth0 label eth0:1
}
}
vrrp_instance mysql {
state BACKUP
interface eth0
garp_master_delay 10
smtp_alert
virtual_router_id 51
priority 80

authentication {
auth_type PASS
auth_pass 123456
}
virtual_ipaddress {
172.31.1.200 dev eth0 label eth0:2
}
}
重启
[root@zabbix-ha1 ~]# systemctl restart keepalived.service
查看会看到两个vip
[root@zabbix-ha1 ~]# ip a
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 00:0c:29:d3:f0:ed brd ff:ff:ff:ff:ff:ff

inet 172.31.1.100/32 scope global eth0:1
valid_lft forever preferred_lft forever
inet 172.31.1.200/32 scope global eth0:2
把配置文件拷贝到远端ha机器
[root@zabbix-ha1 ~]# scp /etc/keepalived/keepalived.conf 172.31.1.35:/etc/keepalived/keepalived.conf
修改内核参数
[root@zabbix-ha1 ~]# vim /etc/sysctl.conf
net.ipv4.ip_forward = 1
net.ipv4.ip_nonlocal_bind = 1
net.ipv6.ip_nonlocal_bind = 1
执行
[root@zabbix-ha2 ~]# sysctl -p
修改haproxy配置文件
[root@zabbix-ha1 ~]# cat /etc/haproxy/haproxy.cfg
listen mysql-3306
bind 172.31.1.200:3306
mode tcp
server 172.31.1.32 172.31.1.32:3306 check inter 2s fall 3 rise 5

重启服务
[root@zabbix-ha1 ~]# systemctl restart haproxy.service
把配置文件拷贝到远端ha机器
[root@zabbix-ha1 ~]# scp /etc/haproxy/haproxy.cfg 172.31.1.35:/etc/haproxy/haproxy.cfg
查看vip
[root@zabbix-ha1 ~]# ip a
inet 172.31.1.100/32 scope global eth0:1
[root@zabbix-ha2 ~]# ip a
inet 172.31.1.200/32 scope global eth0:2
安装数据库（两台都要）
[root@mysql ~]# apt install -y mysql-server
修改配置
[root@mysql ~]# vim /etc/mysql/mysql.conf.d/mysqld.cnf
[mysqld]
bind-address = 0.0.0.0
server-id = 32
log-bin = /var/lib/mysql/master-log
auto-increment-increment = 2
auto-increment-offset = 1
binlog_format = mixed
sync_binlog=1
binlog-do-db=zabbix_server # 同步原数据库名
binlog-ignore-db=mysql # 不同步数据库名
binlog-ignore-db=sys
replicate-do-db=zabbix_server
replicate-ignore-db=mysql
replicate-ignore-db=sys
重启服务
[root@mysql ~]# systemctl restart mysql
下载zabbix
[root@zabbix-master ~]# wget https://repo.zabbix.com/zabbix/4.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.0-3+bionic_all.deb
安装
[root@zabbix-master ~]# dpkg -i zabbix-release_4.0-3+bionic_all.deb
[root@zabbix-master ~]# apt update
安装前端
[root@zabbix-master ~]# apt -y install zabbix-server-mysql zabbix-frontend-php zabbix-agent
登录zabbix数据库
[root@zabbix-master ~]# mysql -uzabbix -p'centos.com' -h 172.31.1.32
导入初始化数据
[root@zabbix-master ~]# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p'centos.com' -h 172.31.1.32 zabbix_server
修改zabbix-server端配置
[root@zabbix-master ~]# vim /etc/zabbix/zabbix_server.conf
SourceIP=172.31.1.100
DBHost=172.31.1.32
DBName=zabbix_server
DBUser=zabbix
DBPassword=centos.com
DBPort=3306
修改php
[root@zabbix-master ~]# vim /etc/zabbix/apache.conf
php_value date.timezone Asia/Shanghai
重启
[root@zabbix-master ~]# systemctl restart zabbix-server.service apache2 zabbix-agent.service
浏览器登录：http://172.31.1.30/zabbix
然后就是web界面
另外一台按同样步骤安装即可
mysql数据库猪猪同步

启动同步（在对方机器操作添加当前机器为master）
172.31.1.33（33操作如下：）
CHANGE MASTER TO

MASTER_LOG_FILE='master-log.000002',

文件同步（这里还不完整需要在查查）
建议使用rsync + sersync
安装
[root@zabbix-master ~]# apt -y install rsync
默认安装但是不开启，修改配置文件即可
[root@zabbix-master ~]# vim /etc/default/rsync
#RSYNC_ENABLE=false
RSYNC_ENABLE=true
增加配置
[root@zabbix-master ~]# cp /usr/share/doc/rsync/examples/rsyncd.conf /etc
修改配置文件
[root@zabbix-master ~]# vim /etc/rsyncd.conf
[zabbix]
uid=root
gid=root
max connections=100
use chroot=true
log file=/var/log/rsyncd.log
motd file = /etc/rsyncd.motd
transfer logging = true
hosts allow= 172.31.1.31
[zabbix]
path=/etc/zabbix/
exclude = web
comment = etc zabbix
read only = no
list = yes
auth users = root
secrets file=/etc/rsyncd.pwd
[web1]
#path=/etc/httpd/conf/ # 这是CentOS系统的
path=/etc/apache2/
#comment = httpd conf # 这是CentOS系统的
comment = apache2 conf
read only = no
list = yes
auth users = root
secrets file=/etc/rsyncd.pwd
[web2]
#path=/etc/httpd/conf/ # 这是CentOS系统的
path=/etc/apache2/
#comment = httpd conf # 这是CentOS系统的
comment = apache2 conf
read only = no
list = yes
auth users = root
secrets file=/etc/rsyncd.pwd
制作密码
[root@zabbix-master ~]# cat /etc/rsyncd.pwd
root:Root$130
[root@zabbix-master ~]# cat /etc/rsyncd.pwd2
Root$130
rsyncd.conf文件与主机相同，只是 ‘ hosts allow= 172.31.1.30 ’
同步的文件为/etc/zabbix/（不包括web）、/etc/httpd/conf/和/etc/httpd/conf.d/，可根据实际情况增减。
验证主从连接状态
[root@zabbix-master zabbix]# rsync -vzrtopg --progress root@172.31.1.31::zabbix --password-file=/etc/rsyncd.pwd2
同步数据
注意：
–delete ：以SRC为主，对DEST进行同步。多则删之，少则补之。
[root@zabbix-master zabbix]# rsync -avzPt --delete --password-file=/etc/rsyncd.pwd2 root@172.31.1.31::zabbix /etc/zabbix/
主备都要
[root@zabbix-master ~]# nohup rsync --daemon --config=/etc/rsyncd.conf &
文件同步测试
[root@zabbix-master apache2]# cd /etc/apache2/ && mkdir dropme1 && cd /etc/apache2/ && mkdir dropme2 && cd /etc/zabbix/ && mkdir dropme3
inotify 安装
[root@zabbix-master ~]# apt -y install inotify-tools
编写监控同步脚本

使用vip登录zabbix
需要创建zabbix用户
先查看zabbix-server
[root@zabbix-master ~]# id zabbix
uid=113(zabbix) gid=115(zabbix) groups=115(zabbix)
ha服务器创建zabbix用户
[root@zabbix-ha2 ~]# groupadd -g 115 zabbix && useradd -u 115 -r -g 115 -s /usr/sbin/nologin zabbix
