重启(指定服务)
使用 -c 指定服务来重启，这里指定 oceanbase-ce 重启
[admin@server070 oceanbase-ce]$ obd cluster restart demo -c oceanbase-ce Get local repositories and plugins ok Load cluster param plugin ok Open ssh connection ok Cluster status check ok Check before restart observer ok Connect to observer x [ERROR] OBD-1006: Failed to connect to oceanbase-ce Observer restart ok Wait for observer init ok +---------------------------------------------+ | observer | +-----------+---------+------+-------+--------+ | ip | version | port | zone | status | +-----------+---------+------+-------+--------+ | 127.0.0.1 | 4.2.2.0 | 2881 | zone1 | ACTIVE | +-----------+---------+------+-------+--------+ obclient -h127.0.0.1 -P2881 -uroot -Doceanbase -A succeed Trace ID: 091ce1c0-ece2-11ee-9b14-000c2910d46f If you want to view detailed obd logs, please run: obd display-trace 091ce1c0-ece2-11ee-9b14-000c2910d46f [admin@server070 oceanbase-ce]$ [admin@server070 oceanbase-ce]$
也可以使用 -s 指定重启的具体节点
obd cluster restart demo -c oceanbase-ce -s 127.0.0.1
手动重启
停止节点服务
obclient [oceanbase]> alter system stop server '127.0.0.1:2882';
obclient [oceanbase]> ALTER SYSTEM MINOR FREEZE SERVER = ('127.0.0.1:2882'); ----进行转储
注意: 单机条件下 不满足paxos协议，此操作不允许
停掉 observer 进程
kill xxx
重启
cd /home/admin/oceanbase-ce ./bin/observer
obproxy重启
使用obd重启
可以使用 -s 指定 特定节点 的obproxy 重启
[admin@server070 oceanbase-ce]$ obd cluster restart demo -c obproxy-ce -s 127.0.0.1 Get local repositories and plugins ok Load cluster param plugin ok Open ssh connection ok Cluster status check ok Check before start obproxy ok Stop obproxy ok Start obproxy ok obproxy program health check ok Connect to obproxy ok +---------------------------------------------+ | obproxy | +-----------+------+-----------------+--------+ | ip | port | prometheus_port | status | +-----------+------+-----------------+--------+ | 127.0.0.1 | 2883 | 2884 | active | +-----------+------+-----------------+--------+ obclient -h127.0.0.1 -P2883 -uroot -Doceanbase -A succeed Trace ID: ec2765e0-ece1-11ee-934b-000c2910d46f If you want to view detailed obd logs, please run: obd display-trace ec2765e0-ece1-11ee-934b-000c2910d46f [admin@server070 oceanbase-ce]$ [admin@server070 oceanbase-ce]$ [admin@server070 oceanbase-ce]$
手动重启
将 obporxy-ce进程 和 obproxyd守护进程 杀掉
[admin@server070 ~]$ ps -ef|grep obproxy |grep -v grep admin 15091 1 0 17:02 pts/0 00:00:01 bash /home/admin/obproxy-ce/obproxyd.sh /home/admin/obproxy-ce 127.0.0.1 2883 daemon admin 15110 1 1 17:02 ? 00:00:39 /home/admin/obproxy-ce/bin/obproxy --listen_port 2883 [admin@server070 ~]$ [admin@server070 ~]$ [admin@server070 ~]$ [admin@server070 ~]$ [admin@server070 ~]$ kill 15091 [admin@server070 ~]$ [admin@server070 ~]$ [admin@server070 ~]$ [admin@server070 ~]$ kill 15110 [admin@server070 ~]$ [admin@server070 ~]$
启动 obproxy 节点
[admin@server070 ~]$ cd /home/admin/obproxy-ce/ [admin@server070 obproxy-ce]$ ./bin/obproxy [admin@server070 obproxy-ce]$ [admin@server070 obproxy-ce]$ chmod 733 obproxyd.sh [admin@server070 obproxy-ce]$ [admin@server070 obproxy-ce]$ [admin@server070 obproxy-ce]$ [admin@server070 obproxy-ce]$ sh obproxyd.sh /home/admin/obproxy-ce 127.0.0.1 2883 [admin@server070 obproxy-ce]$ [admin@server070 obproxy-ce]$ [admin@server070 obproxy-ce]$ ps -ef | grep obproxy | grep -v grep admin 27105 1 2 17:37 ? 00:00:01 ./bin/obproxy [admin@server070 obproxy-ce]$ ps -ef | grep obproxy admin 27105 1 2 17:37 ? 00:00:02 ./bin/obproxy admin 27451 15200 0 17:39 pts/0 00:00:00 grep --color=auto obproxy [admin@server070 obproxy-ce]$ [admin@server070 obproxy-ce]$
