MySQL infobright的安装步骤

整个安装过程过了一遍，感觉跟mysql的安装差不太多。步骤如下：

1、使用"rpm -ivh  安装包"命令来安装一下rpm的包，如下：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51

[root@tk01-dba-mysql dba_mysql]# rpm -ivh infobright-4.0.7-0-x86_64-ice.rpm --prefix=/usr/local preparing...             ################################# [100%] installing infobright 4.0.7-0 (x86_64) the installer will generate /tmp/ib4.0.7-0-install.log install trace log. updating / installing...   1:infobright-4.0.7-0        ################################# [100%] creating/updating datadir and cachedir creating user mysql and group mysql installing default databases installing mysql system tables... ok filling help tables... ok   to start mysqld at boot time you have to copy support-files/mysql.server to the right place for your system   please remember to set a password for the mysql root user ! to do so, start the server, then issue the following commands:   /usr/local/infobright-4.0.7-x86_64/bin/mysqladmin -u root password 'new-password' /usr/local/infobright-4.0.7-x86_64/bin/mysqladmin -u root -h tk01-dba-mysql-7-197 password 'new-password'   alternatively you can run: /usr/local/infobright-4.0.7-x86_64/bin/mysql_secure_installation   which will also give you the option of removing the test databases and anonymous user created by default. this is strongly recommended for production servers.   see the manual for more instructions.   you can start the mysql daemon with: cd /usr/local/infobright-4.0.7-x86_64 ; /usr/local/infobright-4.0.7-x86_64/bin/mysqld_safe &   you can test the mysql daemon with mysql-test-run.pl cd /usr/local/infobright-4.0.7-x86_64/mysql-test ; perl mysql-test-run.pl   please report any problems with the /usr/local/infobright-4.0.7-x86_64/scripts/mysqlbug script!   the latest information about mysql is available at http://www.mysql.com/ support mysql by buying support/licenses from http://shop.mysql.com/   system physical memory: 15866(mb) infobright optimal servermainheapsize is set to 6000(mb) infobright optimal loadermainheapsize is set to 800(mb) infobright server installed into folder /usr/local/infobright installation log file /tmp/ib4.0.7-0-install.log -------------------------------------- to activate infobright server, please run ./postconfig.sh script from /usr/local/infobright-4.0.7-x86_64. example command: cd /usr/local/infobright-4.0.7-x86_64; ./postconfig.sh

我这里是将文件解压到了/usr/local/目录下面，如果有其他目录，则可以使用其他目录进行解压，解压后的文件如下：

?

1 2 3 4 5 6 7 8 9 10

[root@tk01-dba-mysql local]# ll total 54932 drwxr-xr-x. 2 root   root    20 oct 11 11:45 bin drwxr-xr-x  8 root   root   297 sep 27 09:10 cma_tcollector drwxr-xr-x. 2 root   root    6 apr 11 2018 etc drwxr-xr-x. 2 root   root    6 apr 11 2018 games drwxr-xr-x. 2 root   root    6 apr 11 2018 include lrwxrwxrwx  1 root   root    34 oct 15 21:42 infobright -> /usr/local/infobright-4.0.7-x86_64 -rw-r--r--  1 root   root 56249223 oct 15 21:30 infobright-4.0.7-0-x86_64-ice.rpm drwxr-xr-x 11 root   root   252 oct 15 21:42 infobright-4.0.7-x86_64

2、根据最后一行提示，激活infobright server，运行脚本./postconfig.sh ，如下：

?

1 2 3 4 5 6 7 8

[root@tk01-dba-mysql infobright]# ./postconfig.sh infobright post configuration -------------------------------------- infobright server activated. -------------------------------------- register your copy of ice and receive a free copy of the user manual (a $50 value) as well as a copy of the bloor research spotlight report "what's cool about columns" which explains the differences and benefits of a columnar versus row database. registration will require opening an http connection to infobright, do you wish to register now? [y/n]: n register now http://www.infobright.org/downloads/ice/.

第一次运行的时候，会提醒是否注册，选择n，不注册，此时再次运行这个脚本：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

[root@tk01-dba-mysql infobright]# ./postconfig.sh infobright post configuration -------------------------------------- using postconfig you can: -------------------------------------- (1) move existing data directory to other location, (2) move existing cache directory to other location, (3) configure server socket, (4) configure server port, (5) relocate datadir path to an existing data directory.   please type 'y' for option that you want or press ctrl+c for exit.   current configuration:   -------------------------------------- current config file: [/etc/my-ib.cnf] current brighthouse.ini file: [/usr/local/infobright-4.0.7-x86_64/data/brighthouse.ini] current datadir: [/usr/local/infobright-4.0.7-x86_64/data] current cachefolder in brighthouse.ini file: [/usr/local/infobright-4.0.7-x86_64/cache] current socket: [/tmp/mysql-ib.sock] current port: [5029] --------------------------------------   (1) do you want to copy current datadir [/usr/local/infobright-4.0.7-x86_64/data] to a new location? [y/n]:y give new datadir path (e.g. /opt/datadirnewpath/data):/data/infobright_5029/data (2) option to change cachefolder is disabled when option 1 is chosen! (3) do you want to change current socket [/tmp/mysql-ib.sock]? [y/n]:n (4) do you want to change current port [5029]? [y/n]:n (5) relocation is disabled when options 1-4 are chosen!   -------------------------------------- datadir(/usr/local/infobright-4.0.7-x86_64/data) is going to be copied to /data/infobright_5029/data --------------------------------------   please confirm to proceed? [y/n]:y copying /usr/local/infobright-4.0.7-x86_64/data to /data/infobright_5029/data ...is done. you can now remove/backup your old /usr/local/infobright-4.0.7-x86_64/data ... done!

此时安装包会提示是否修改相关的目录，按照自己的需求去修改，我这里只是简单的改了下data盘的目录，其他的选项都选择的是n，这样最终有一条提示：

datadir(/usr/local/infobright-4.0.7-x86_64/data) is going to be copied to /data/infobright_5029/data

   一路yes，就安装完毕了。

3、查看data文件。此时进入刚才设定的data目录，/data/infobright_5029/data里面，查看初始化好的文件。

?

1 2 3 4 5 6 7 8

[root@tk01-dba-mysql data]# ll total 16 -rw-rw---- 1 mysql mysql  0 oct 15 21:42 bh.err -rw-r--r-- 1 mysql mysql 1898 oct 15 21:42 brighthouse.ini -rw-r--r-- 1 mysql mysql  8 oct 15 21:42 ib_data_version drwxr-xr-x 2 mysql mysql 4096 oct 15 21:42 mysql drwxr-xr-x 2 mysql mysql 4096 oct 15 21:42 sys_infobright drwxr-xr-x 2 mysql mysql  6 oct 15 21:42 test

4、启动服务。安装完软件之后，使用自带的工具/etc/init.d/mysqld-ib启动服务，启动完之后可以查看相关进程，启动方法和进程查看方法如下：

?

1 2 3 4 5 6 7 8

[root@tk01-dba-mysql infobright_5029]# /etc/init.d/mysqld-ib start starting mysql. success! [root@tk01-dba-mysql-7-195 infobright_5029]# ps -ef|grep 5029 root   78369   1 0 10:34 pts/1  00:00:00 sudo -u mysql /usr/local/infobright-4.0.7-x86_64/bin/mysqld_safe --defaults-file=/etc/my-ib.cnf --log-queries-not-using-indexes --user=mysql --pid-file=/data/infobright_5029/data/tk01-dba-mysql-7-195.pid mysql   78372 78369 0 10:34 pts/1  00:00:00 /bin/sh /usr/local/infobright-4.0.7-x86_64/bin/mysqld_safe --defaults-file=/etc/my-ib.cnf --log-queries-not-using-indexes --user=mysql --pid-file=/data/infobright_5029/data/tk01-dba-mysql-7-195.pid mysql   78507 78372 0 10:34 pts/1  00:00:00 /usr/local/infobright-4.0.7-x86_64/bin/mysqld --defaults-file=/etc/my-ib.cnf --basedir=/usr/local/infobright-4.0.7-x86_64 --datadir=/data/infobright_5029/data --log-queries-not-using-indexes --log-error=/data/infobright_5029/data/bh.err --pid-file=/data/infobright_5029/data/tk01-dba-mysql-7-195.pid --socket=/tmp/mysql-ib.sock --port=5029 root   78570 68493 0 10:35 pts/1  00:00:00 grep --color=auto 5029 [root@tk01-dba-mysql-7-195 infobright_5029]#

5、创建root用户的密码，这一步和mysql很像，使用/usr/local/infobright/bin/mysqladmin创建密码,方法如下：

?

1 2	[root@tk01-dba-mysql bin]# ./mysqladmin -uroot password '123456' warning: ./mysqladmin: unknown variable 'loose-local-infile=1'

6、连接数据库，连接方法：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

[root@tk01-dba-mysql bin]# mysql-ib -uroot -p123456 welcome to the mysql monitor. commands end with ; or \g. your mysql connection id is 2 server version: 5.1.40 build number (revision)=ib_4.0.7_r16961_17249(ice) (static)   type 'help;' or '\h' for help. type '\c' to clear the current input statement.   mysql> show databases; +--------------------+ | database      | +--------------------+ | information_schema | | bh_rsi_repository | | mysql       | | sys_infobright   | | test        | +--------------------+ 5 rows in set (0.00 sec)   mysql> show engines; +-------------+---------+-----------------------------------------------------------+--------------+------+------------+ | engine   | support | comment                          | transactions | xa  | savepoints | +-------------+---------+-----------------------------------------------------------+--------------+------+------------+ | brighthouse | default | brighthouse storage engine                | yes     | no  | no     | | mrg_myisam | yes   | collection of identical myisam tables           | no      | no  | no     | | csv     | yes   | csv storage engine                    | no      | no  | no     | | myisam   | yes   | default engine as of mysql 3.23 with great performance  | no      | no  | no     | | memory   | yes   | hash based, stored in memory, useful for temporary tables | no      | no  | no     | +-------------+---------+-----------------------------------------------------------+--------------+------+------------+ 5 rows in set (0.00 sec)

   如果不设置进入infobright的用户名和密码，则可以直接使用命令mysql-ib进入上述界面。可以看到，默认的存储引擎是brighthouse。到这里，infobright的安装过程算是全部完成了。

7、导入数据。

    社区版的目前只能通过load data的方法进行数据导入，语法如下：

?

1 2 3 4 5 6 7 8 9 10 11 12 13

load data [low_priority| concurrent] [local] infile 'file_name.txt' [replace | ignore]  into table tbl_name  [fields      [terminated by 'string']      [[optionally] enclosed by 'char']      [escaped by 'char' ]  ] [lines    [starting by 'string']    [terminated by 'string']  ]  [ignore number lines]  [(col_name_or_user_var,...)]  [set col_name = expr,...)]

其中有很多关键字信息，这里解释一些重要的：

• low_priority关键字

   如果load data语句使用了low_priority关键字，则在碰到其他会话操作相同表时，则会延迟执行load data语句，直到其他会话操作表结束为止。

• replace和ignore关键字

 控制对现有的唯一键记录的重复的处理。如果你指定replace，新行将代替有相同的唯一键值的现有行。如果你指定ignore，跳过有唯一键的现有行的重复行的输入。

• fields关键字

指定了文件字段的分割格式：

• terminated by关键字

以什么字符作为分隔符；

• enclosed by

字段括起字符；

• lines

指定了每条记录的分隔符默认为'\n'即为换行符；

   更多信息，请参考官方文档。

   现在我们生成一个文本，然后写入数据：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

mysql> use test; database changed mysql> show tables; +----------------+ | tables_in_test | +----------------+ | test      | +----------------+ 1 row in set (0.00 sec)   mysql> load data infile '/tmp/a.txt' ignore into table test character set utf8 fields terminated by ' ' lines terminated by '\n';       query ok, 4 rows affected (0.04 sec) records: 4 deleted: 0 skipped: 0 warnings: 0   mysql> system cat /tmp/a.txt 1  aaa 2  bbb 3  ccc 4  ddd   mysql> select * from test; +------+-------+ | id  | name | +------+-------+ |  1 |  aaa | |  2 |  bbb | |  3 |  ccc | |  4 |  ddd | +------+-------+ 4 rows in set (0.00 sec)

   最终，所有的数据都导入了。大家可以尝试用这种方法导入大量的数据，然后对infobright的查询性能进行评估。
