mongodb单节点,并开启事务

1、将程序挪到工作目录

mkdir -p /data/mongodb；cd mongodb-linux-x86_64-rhel70-4.2.0；mv ./* /data/mongodb

2、添加环境变量

vim /etc/profile
MONGODB_HOME=/data/mongodb
PATH=$MONGODB_HOME/bin:$PATH

3、创建数据目录，日志目录

cd /data/mongodb
mkdir {conf,data,log}

4、创建配置文件

vim /data/mongodb/conf/mongo.conf
systemLog:
   destination: file
   path: "/data/mongodb/mongod.log"
   logAppend: true
storage:
   dbPath: /data/mongodb/data
   journal:
      enabled: true
   wiredTiger:
      engineConfig:
         cacheSizeGB: 8
processManagement:
   fork: true
net:
   bindIp: 0.0.0.0      注意这里，默认是127.0.0.1，会拒绝远程连接
   port: 27017
replication:
  replSetName: rs0
setParameter:
   enableLocalhostAuthBypass: false

5、启动服务

mongod -f /data/mongodb/conf/mongo.conf

6、测试连接

mongo --port 27017

7、开启事务初始化

rs.initiate({_id:"rs0",members:[{_id:0,host:"127.0.0.1:27017",priority:1}]})

8、创建用户

rs0:PRIMARY> use admin
switched to db admin
rs0:PRIMARY> db.createUser({user:"root",pwd:"mima",roles:[{role:"userAdminAnyDatabase",db:"admin"},{role:"clusterAdmin",db:"admin"},{role:"root",db:"admin"}]})
Successfully added user: {
        "user" : "root",
        "roles" : [
                {
                        "role" : "userAdminAnyDatabase",
                        "db" : "admin"
                },
                {
                        "role" : "clusterAdmin",
                        "db" : "admin"
                },
                {
                        "role" : "root",
                        "db" : "admin"
                }
        ]
}
