oceanbase集群部署成功后，启动集群失败，报错Cluster bootstrap x、Cluster init failed，并同时带有两个WARN。

[root@oceanbase ~]# obd cluster start rundbaGet local repositories and plugins ok[WARN] (192.168.80.20) fs.aio-max-nr must not be less than 1048576 (Current value: 65536)[WARN] (192.168.80.20) open files number must not be less than 655350 (Current value: 1024)Start observer okobserver program health check okConnect to observer okInitialize clusterCluster bootstrap xCluster init failed

相关参数未设置。

消除告警，修改配置文件，增加参数。

1）sysctl.conf添加内容

echo "fs.aio-max-nr=1048576" >> /etc/sysctl.conf

配置生效

sysctl -p

2） open files参数修改

vim etc/security/limits.conf #添加内容* soft nofile 655350* hard nofile 655350

退出会话，重新登录，再次运行即可。

open files限制已生效。

[root@oceanbase ~]# ulimit -n655350
