在/etc/profile里面加上node
export CRATE_HEAP_SIZE=4g
crate.yml文件配置:sql
# 本配置文件适用crate 2.0.3版本,低版本配置略有不一样 # 节点名称 node.name: node1 # 集群名称,使用同一个名称表示在同一个集群中 cluster.name: einvoice gateway.expected_nodes: 3 gateway.recover_after_nodes: 2 gateway.recover_after_time: 5m # 高可用配置,集群最小存活节点数 discovery.zen.minimum_master_nodes: 2 # 集群互ping地址 discovery.zen.ping.unicast.hosts: - node1:4300 - node2:4300 - node3:4300 bootstrap.memory_lock : true path: conf: /home/hadmin/crate/config logs: /home/hadmin/data/crate/logs data: /home/hadmin/data/crate blobs.path: /home/hadmin/data/crate/crate_blob_data/disk # 这个是crate 快照备份的地址,暂时没有配置 # Paths where Repositories of type fs may be created: #path.repo: /path/to/shared/fs,/other/shared/fs # 网络绑定地址,默认绑定localhost,最好是绑定主机名 network.host: node1 # 开启crate jdbc支持及访问端口 psql.enabled: true psql.port: 5432
而后启动bootstrap
./crate -dvim
日志报错bash
[2017-07-06T14:23:30,424][ERROR][o.e.b.BootstrapProxy ] [node1] node validation exception bootstrap checks failed max file descriptors [4096] for crate process is too low, increase to at least [65536] max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
启动出错,文件描述符过低网络
修改这个参数须要使用root登录,查看当前该参数设置:app
[root@dscn1 logs]# ulimit -Hn 4096 [root@dscn1 logs]#
执行修改jvm
vim /etc/security/limits.conf
添加对hadmin用户的设置,由于我要使用hadmin用户启动crate日志
hadmin soft nofile 65536 hadmin hard nofile 65536 # 或者能够直接设置为所有 * soft nofile 65536 * hard nofile 65536
有人说,root的nofile要大于等于其它用户的nofile,这个我不是很确定,那若是这样的话,修改任一用户的nofile后,都须要将root的nofile至少要大于等于这个值code
保存,退出用户从新登陆,使配置生效,切换到hadmin用户查看
[hadmin@dscn1 logs]$ ulimit -Hn 65536 [hadmin@dscn1 logs]$
已经修改完毕
下一个异常
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
修改文件
vi /etc/sysctl.conf
添加下列配置,我理解这个配置至关于设置jvm Xms=256m
vm.max_map_count=262144
并执行命令使之生效
sysctl -p
可能还会有这个异常

在/etc/security/limits.conf添加以上内容便可
