ubuntu install mongodb

 

1、查看自己当前系统相关信息: 

    uname -a 

    输出信息:x86_64 x86_64 x86_64 GNU/Linux 

    ok,可以看到,我的系统是x86_64的,所以下一步是要到官网下载自己对应的版本信息 

 

2、下载mongodb 

    到官网下载对应的版本,在这里我下载的是Linux 64-bit版本的 

 

3、解压并安装mongodb 

    tar zxvf mongodb-linux-x86_64-2.4.3.tgz 

    sudo mv  mongodb-linux-x86_64-2.4.3  /usr/local/mongodb 

 

4、启动mongodb 

    cd /usr/local/mongodb/bin 

    ./mongodb 

    这个时候应该会报错: 

     ERROR: dbpath (/data/db/) does not exist. 

     Create this directory or give existing directory in --dbpath. 

     See http://dochub.mongodb.org/core/startingandstoppingmongo 

     从报错信息可以看出,mongodb默认的数据存储路径是在/data/db目录下的,这个错误提示我们,还没有这个目录,那么接下来我们就创建这个目录 

     sudo mkdir -p /data/db 

     sudo chmod 777 -R /data 

     因为要保证mongodb能够对/data目录具有可写权限,所以这里我将该目录改为777. 

     接下来我们再试试,看看能不能启动 

     ./mongodb 

     但是我发现还是有错误,大概是类似于这样的信息: 

     terminate called after throwing an instance    of'std::runtime_error' 

     what(): locale::facet::_S_create_c_locale name not valid 

     Aborted (core dumped) 

     到google去找,发现一种解决办法就是在启动mongodb之前执行这句: 

     export LC_ALL=C,当时不知道是什么意思,但是之后在启动mongodb,发现确实是可以了,后来发现,这句的意思是将你所有的本地化设置都清除。貌似是mongodb在启动的时候会检查你的系统本地化设置的缘故吧,无奈,不能每次启动之前都来这么一句吧,所以,干脆直接改配置文件/etc/default/locale,内容如下: 

     LANG="en_US.UTF-8" 

     LANGUAGE="en_US:en" 

     LC_NUMERIC="en_US.UTF-8" 

     LC_TIME="en_US.UTF-8" 

     LC_MONETARY="en_US.UTF-8" 

     LC_PAPER="en_US.UTF-8" 

     LC_NAME="en_US.UTF-8" 

     LC_ADDRESS="en_US.UTF-8" 

     LC_TELEPHONE="en_US.UTF-8" 

     LC_MEASUREMENT="en_US.UTF-8" 

     LC_IDENTIFICATION="en_US.UTF-8" 

     LC_ALL= 

     之后重启电脑,然后启动mongodb,发现一切正常。 

 

5、设置启动参数 

     -journal 代表要写日志,-maxConns=2400代表mongodb 可以接受2400个tcp连接,-rest代表可以允许客户端通过rest API访问mongdb server,还可以使用参数—quiet启动可以指定安静模式减少记录的项目数,注意使用该参数必须要同时指定日志路径,比如: 

—quiet —logpath /data/db/journal/mongdb.log 

     ok,说做就做,那么我们来试试看: 

     ./mongod -journal -maxConns=2400 -rest -quiet --logpath /data/db/journal/mongodb.log 

     我们去log里面查看输出的log信息,发现如下: 

     Fri May 17 18:35:54.469 [initandlisten] MongoDB starting : pid=8953 port=27017 dbpath=/data/db/ 64-bit host=naitnix-ThinkPad-SL410 

     Fri May 17 18:35:54.490 [initandlisten] db version v2.4.3 

     Fri May 17 18:35:54.490 [initandlisten] git version: fe1743177a5ea03e91e0052fb5e2cb2945f6d95f 

     Fri May 17 18:35:54.490 [initandlisten] build info: Linux ip-10-2-29-40 2.6.21.7-2.ec2.v1.2.fc8xen #1 SMP Fri Nov 20 17:48:28 EST 2009 x86_64 BOOST_LIB_VERSION=1_49 

     Fri May 17 18:35:54.490 [initandlisten] allocator: tcmalloc 

     Fri May 17 18:35:54.491 [initandlisten] options: { journal: true, logpath: "/data/db/journal/mongodb.log", maxConns: 2400, quiet: true, rest: true } 

     Fri May 17 18:35:54.571 [initandlisten] journal dir=/data/db/journal 

     Fri May 17 18:35:54.571 [initandlisten] recover : no journal files present, no recovery needed 

     Fri May 17 18:35:54.769 [initandlisten]  --maxConns too high, can only handle 819 

     Fri May 17 18:35:54.769 [websvr] admin web console waiting for connections on port 28017 

     Fri May 17 18:35:54.770 [initandlisten] waiting for connections on port 27017 

 

     通过以上信息,我们可以看到,大部分都是我们在启动的时候设置的参数,但是有一个地方需要我们注意: 

     --maxConns too high, can only handle 819 

     这句话是说,最大连接数太高了,只能设置到819 

     最大连接数目的限制原因是Linux系统默认最大文件打开数目为1024,用ulimit -a 命令检查,可以看到下面这行:  

     open files  (-n) 1024 

     修改/etc/security/limits.conf 配置文件,增加如下两行: 

     * soft nofile 3000 

     * hard nofile 20000 

     重启电脑,运行ulimit -a,发现最大连接数已经改变: 

     open files  (-n) 3000 

     接下来,我们启动mongodb试试看:./mongod -journal -maxConns=2400 -rest -quiet --logpath /data/db/journal/mongodb.log 

     我们发现,上面所说的--maxConns too high, can only handle 819已经不见了。 

 

6、其他参数说明: 

     --port    表示数据库端口,默认27017 

     --dbpath  表示数据文件存储路径 

     --logpath 表示日志文件存储路径 

     --logappend 表示日志追加,默认是覆盖 

     --directoryperdb 表示每个db一个目录

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.
