activitimq集群搭建_activitmq+keepalived+nfs 非zk的高可用集群构建
nfs
192.168.10.32
maast
192.168.10.4
savel
192.168.10.31
應對這個需求既要高可用又要消息延遲,只能使用變態方式實現
nfs部署
#yum install nfs-utils rpcbind
#vim /etc/exports
/data/activemq 192.168.10.31(rw,sync,no_root_squash,no_all_squash)
/data/activemq 192.168.10.4(rw,sync,no_root_squash,no_all_squash)
#systemctl stop firewalld.service
#setenforce 0
#mkdir /data/activemq -p
#systemctl start nfs
客戶端掛載
#yum -y install nfs-utils.x86_64
# systemctl start rpcbind
# showmount -e 192.168.10.32
Export list for 192.168.10.32:
/data/activemq 192.168.10.4,192.168.10.31
# mkdir /data
# mount -t nfs 192.168.10.32:/data/activemq /data
# df -h

使用yum安裝keepalived
# yum -y install epel-release-7-11.noarch
# yum -y install keepalived
安裝activemq部署
# tar xf apache-activemq-5.15.8-bin.tar.gz -C /usr/local/
# cd /usr/local/apache-activemq-5.15.8/conf
# vim activemq.xml 改成這樣的兩個節點都一樣

82
83
# ./activemq start 啟動
# ss -lntp | grep 61616
LISTEN 0 128 :::61616 :::* users:(("java",pid=21705,fd=137))
查另一個節點的端口
# ss -lntp | grep 61616
注意
1、共享文件的主從配置,是通過文件共享鎖來實現的。先拿到文件鎖的服務就是master,其它為slave服務,slave服務默認每10秒試圖拿一次文件鎖,可以查看activeMq的控制臺。
2、只有master的控制臺(如http://192.168.10.4:8161/admin)能夠訪問,slave的控制臺不能訪問,原因就是slave沒有拿到文件鎖,不能訪問文件。
配置keepalived的文件
備節點的配置
[root@localhost conf]# cd /etc/keepalived/
[root@localhost keepalived]# cat keepalived.conf
global_defs {
notification_email {
root@localhost
}
notification_email_from ka2@localhost
smtp_server 127.0.0.1
smtp_connect_timeout 30
vrrp_mcast_group4 224.111.111.111
}
vrrp_script chk_mq {
script "ss -lntp | grep 61616" #檢查端口是否存在，這里不能查進程
interval 2
weight -10
fall 2
rise 2
}
vrrp_instance External_1 {
state BACKUP
interface ens33
virtual_router_id 171
priority 95
advert_int 1
authentication {
auth_type PASS
auth_pass 1402b1b5
}
virtual_ipaddress {
192.168.10.5/24
}
track_script {
chk_mq
}
}
主節點的配置
# cat /etc/keepalived/keepalived.conf
global_defs {
notification_email {
root@localhost
}
notification_email_from ka1@localhost
smtp_server 127.0.0.1
smtp_connect_timeout 30
vrrp_mcast_group4 224.111.111.111
}
vrrp_script chk_mq {
script "ss -lntp | grep 61616"
interval 2
weight -10
fall 2
rise 2
}
vrrp_instance External_1 {
state MASTER
interface ens33
virtual_router_id 171
priority 100
advert_int 1
authentication {

auth_pass 1402b1b5
}
virtual_ipaddress {
192.168.10.5/24
}

}
}
驗證

重啟activemq查看vip切換效果，注意誰先起誰就是主節點，主節點掛了釋放文件鎖后，從節點端口才能啟動
