在Debian上实现TigerVNC的高可用性可以通过多种方式来实现,以下是一些常见的方法:
安装Keepalived和LVS:
sudo apt-get update
sudo apt-get install keepalived lvs
配置Keepalived:
编辑Keepalived配置文件 /etc/keepalived/keepalived.conf
,添加以下内容:
vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_router_id 51
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 42
}
virtual_ipaddress {
192.168.1.100
}
}
virtual_server 192.168.1.100 5900 {
delay_loop 6
lb_algo rr
lb_kind DR
nat_mask 255.255.255.0
persistence_timeout 50
protocol TCP
real_server 192.168.1.101 5900 {
weight 1
TCP_CHECK {
connect_timeout 10
connect_port 5900
}
}
real_server 192.168.1.102 5900 {
weight 1
TCP_CHECK {
connect_timeout 10
connect_port 5900
}
}
}
配置TigerVNC服务器: 在两台服务器上安装TigerVNC并启动服务:
sudo apt-get install tigervnc-standalone-server tigervnc-common
编辑 /etc/systemd/system/tigervncserver@.service
文件,添加以下内容:
[Unit]
Description=Start TigerVNC server at startup
After=syslog.target network.target
[Service]
Type=forking
User=<your_user>
Group=<your_group>
WorkingDirectory=/home/<your_user>
PIDFile=/home/<your_user>/.vnc/%H:%i.pid
ExecStartPre=-/usr/bin/vncserver -kill :%i > /dev/null 2>&1
ExecStart=/usr/bin/vncserver -depth 24 -geometry 1280x800 :%i
ExecStop=/usr/bin/vncserver -kill :%i
[Install]
WantedBy=multi-user.target
启动服务:
sudo systemctl daemon-reload
sudo systemctl start tigervncserver@1.service
sudo systemctl enable tigervncserver@1.service
启动Keepalived:
sudo systemctl start keepalived
sudo systemctl enable keepalived
安装HAProxy:
sudo apt-get update
sudo apt-get install haproxy
配置HAProxy:
编辑 /etc/haproxy/haproxy.cfg
文件,添加以下内容:
frontend vnc_frontend
bind *:5900
default_backend vnc_backend
backend vnc_backend
balance roundrobin
server vnc1 192.168.1.101:5900 check
server vnc2 192.168.1.102:5900 check
配置TigerVNC服务器: 在两台服务器上安装TigerVNC并启动服务,配置方法同上。
启动HAProxy:
sudo systemctl start haproxy
sudo systemctl enable haproxy
安装Pacemaker和Corosync:
sudo apt-get update
sudo apt-get install pacemaker corosync
配置Corosync:
编辑 /etc/corosync/corosync.conf
文件,添加以下内容:
totem {
version: 2
cluster_name: vnc_cluster
transport: udpu
}
nodelist {
node {
ring0_addr: <node_ip>
nodeid: 1
}
node {
ring0_addr: <another_node_ip>
nodeid: 2
}
}
quorum {
provider: corosync_votequorum
}
logging {
to_logfile: yes
logfile: /var/log/corosync/corosync.log
to_syslog: yes
}
启动Corosync和Pacemaker:
sudo systemctl start corosync
sudo systemctl enable corosync
sudo systemctl start pacemaker
sudo systemctl enable pacemaker
配置资源:
使用 pcs
命令配置TigerVNC资源:
sudo pcs resource create vnc ocf:heartbeat:tigervnc \
params config="/home/<your_user>/.vnc/xstartup" \
op monitor interval="30s"
sudo pcs resource create vnc_ip ocf:heartbeat:IPaddr2 \
params ip=192.168.1.100 cidr_netmask=24 \
op monitor interval="30s"
sudo pcs constraint colocation add vnc with vnc_ip INFINITY
sudo pcs constraint order vnc_ip then vnc
启动资源:
sudo pcs resource start vnc
sudo pcs resource start vnc_ip
通过以上方法,你可以在Debian上实现TigerVNC的高可用性。选择哪种方法取决于你的具体需求和环境。
