docker_mongodb_rs

基于docker的mongodb分片部署 注意-v映射的数据文件目录，在宿主机上创建对应的目录 详细的部署文档在csdn博客：https://blog.csdn.net/yekoufeng/article/details/83412431

key生成和预拷贝

• openssl rand -base64 745 > /home/mongodb/key.file
• chmod 600 /home/mongodb/key.file
• 拷贝所有.example结尾的文件到/home/mongodb目录，去掉.example后缀(注：key.file,根据每套集群环境不一样而不同，需要自己重新生成)

conf ,log 和testKeyFile.fie放到docker_mongodb_rs的上一级目录

key.file的权限为只读 ，设为 chmod 400 testKeyFile.file

ping not found: apt-get update apt-get install inetutils-ping

配置时的一些命令汇总(无实际意义，方便拷贝，粘贴)

sh.addShard("rs_shardsvr0/172.17.0.6:27018,172.17.0.7:27018,172.17.0.8:27018") sh.addShard("rs_shardsvr1/172.17.0.9:27018,172.17.0.10:27018,172.17.0.11:27018")

sh.enableSharding("test")

sh.shardCollection("test.order", {"_id": "hashed" })

for (i = 1; i <= 1001; i=i+1){ db.order6.insert({"price": 1})

注：把conf.example移动到 上一级目录，并去掉.example
