Mongodb无法启动:The default storage engine 'wiredTiger' is not available with this build of mongod.
今天在linux上安装mongodb后(版本为3.2), 采用命令方式启动mongdb,结果client登不进去, 看了看日志, 发现日志报错
启动命令: ./mongod -port=38200 -dbpath=../data/ -logpath=../log/mongodb.log --logappend --journal;tail -f ../log/mongodb.log
客户端登陆不进去:
[root@centos bin]# ./mongo -port=38200 MongoDB shell version: 3.2.0 connecting to: 127.0.0.1:38200/test 2016-01-05T17:55:27.991+0800 W NETWORK [thread1] Failed to connect to 127.0.0.1:38200, reason: errno:111 Connection refused 2016-01-05T17:55:27.992+0800 E QUERY [thread1] Error: couldn't connect to server 127.0.0.1:38200, connection attempt failed : connect@src/mongo/shell/mongo.js:226:14 @(connect):1:6 exception: connect failed
查看日志记录, 报错:

查阅了一下, mongodb自3.0版本后新增了wiredTiger的数据存储引擎, 3.2版本后默认采用的wiredTiger, 不知道为何, 我的这个版本不能使用该引擎? 难道是版本的问题? 查看版本:
[root@centos bin]# uname -a Linux centos 2.6.32-431.el6.i686 #1 SMP Fri Nov 22 00:26:36 UTC 2013 i686 i686 i386 GNU/Linux
系统采用的是centos版本.
既然默认的wiredTiger不能用, 那么采用指定引擎为mmapv1吧,这应该可以用了吧.
于是命令变更为:
./mongod -port=38200-storageEngine=mmapv1 -dbpath=../data/ -logpath=../log/mongodb.log --logappend --journal;
这时,客户端登陆, 可以登陆了.
但是服务端会挂在那儿, 如果ctrl+c, 会终止mongodb的运行, 需要再加上参数使之后台运行--fork.
最终命令为:
./mongod -port=38200 -storageEngine=mmapv1 -dbpath=../data/ -logpath=../log/mongodb.log --logappend --journal --fork;
至此, 问题解决. 参数可以全部放在一个conf配置文件里面, 命令可以写成一个脚本.
至于为什么会报这个问题: 即mmapv1和wiredTiger引擎的问题, 后续跟进.
