dbpath=/data/mongo_27117/db
logpath=/data/mongo_27117/log/mongo_27117.log
pidfilepath = /data/mongo_27117/tmp/mongo_27117.pid
storageEngine = wiredTiger
wiredTigerCacheSizeGB = 2
syncdelay = 30
wiredTigerCollectionBlockCompressor = zlib
port=27117

directoryperdb = true
oplogSize=2048
logappend=true

journalCommitInterval = 50
slowms = 200
修改目录、文件的权限和属组：
chown -R mongodb:mongodb /data/mongo_27117/
chown -R mongodb:mongodb /etc/mongodb
确认目录和配置文件都已经准备完毕：
ls -l /data/mongo_27117/
ls -l /etc/mongodb
cat /etc/mongodb/mongo_27117.conf
该步骤实际操作过程如下：
[root@linuxidc local]#
[root@linuxidc local]# mkdir -p /data/mongo_27117/{db,log,tmp}
[root@linuxidc local]# mkdir -p /etc/mongodb
[root@yq
-mapp-otadb248 local]#
[root@linuxidc local]#
[root@linuxidc local]# vim /etc/mongodb/mongo_27117.conf
dbpath=/data/mongo_27117/db
logpath=/data/mongo_27117/log/mongo_27117.log
pidfilepath = /data/mongo_27117/tmp/mongo_27117.pid
storageEngine = wiredTiger
wiredTigerCacheSizeGB = 2
syncdelay = 30
wiredTigerCollectionBlockCompressor = zlib
port=27117
auth = true
directoryperdb = true
oplogSize=2048
logappend=true
fork=true
#rest=true
journal = true
journalCommitInterval = 50

5. 启动mongodb实例，修改管理员密码
使用下面的命令启动mongodb服务：
/usr/local/mongodb/bin/mongod --config /etc/mongodb/mongo_27117.conf
确认密码，mongodb的管理员密码，可以根据各自的规则设置：
echo $MONGODB_ROOT_PASS
mongodb_020248_Pass
修改管理员密码，注意 mongodb 3.2要对admin授予三个角色，这点与之前的版本不同：
/usr/local/mongodb/bin/mongo --port=27117
