mongo replica set +sharding实例化文档

1、创建数据文件存储路径
[root@mongoDB ~]# mkdir -p /data/data/r0
[root@mongoDB ~]# mkdir -p /data/data/r1
[root@mongoDB ~]# mkdir -p /data/data/r2
2、创建日志文件路径
[root@mongoDB ~]# mkdir -p /data/log
3、创建主从key文件
[root@mongoDB ~]# mkdir -p /data/key
[root@mongoDB ~]# echo "this is rs1 super secret key" > /data/key/r0
[root@mongoDB ~]# echo "this is rs1 super secret key" > /data/key/r1
[root@mongoDB ~]# echo "this is rs1 super secret key" > /data/key/r2
4.启动3个实例
mongod --replSet rs1 --keyFile /data/key/r0 --fork --port 28010 --dbpath /data/data/r0 --logpath=/data/log/r0.log --logappend
mongod --replSet rs1 --keyFile /data/key/r1 --fork --port 28011 --dbpath /data/data/r1 --logpath=/data/log/r1.log --logappend
mongod --replSet rs1 --keyFile /data/key/r2 --fork --port 28012 --dbpath /data/data/r2 --logpath=/data/log/r2.log --logappend
5.配置及初始化replica sets
mongo -port 28010
config_rs1 = {_id: 'rs1', members: [{_id: 0, host: 'localhost:28010', priority:1},{_id: 1, host: 'localhost:28011'},{_id: 2, host: 'localhost:28012'}]}
rs.initiate(config_rs1);
查看复制集状态
rs.status()

{_id: 1, host: '10.0.0.85:27018'},
{_id: 2, host: '10.0.0.17:27018'}]
}

db.runCommand({addshard:"shard1/10.0.0.6:27017,10.0.0.85:27017,10.0.0.17:27017"});

ERROR: child process failed, exited with error number 1

keyfile文件缺失或生成方式以及文件权限可能有问题

==================================
openssl rand -base64 755 > keyfile
chmod 400 keyfile
