MySQL 是最流行的關(guān)系型數(shù)據(jù)庫管理系統(tǒng)，由瑞典MySQL?AB公司開發(fā)，目前屬于Oracle公司。

MySQL所使用的SQL語言是用于訪問數(shù)據(jù)庫的最常用標準化語言。

MySQL由于其體積小、速度快、總體擁有成本低，尤其是開放源碼這一特點，一般中小型網(wǎng)站的開發(fā)都選擇MySQL作為網(wǎng)站數(shù)據(jù)庫。

MySQL 安裝

本教程的系統(tǒng)平臺：CentOS release 6.6 (Final) 64位。

一、安裝編譯工具及庫文件

yum -y install gcc gcc-c++ make autoconf libtool-ltdl-devel gd-devel freetype-devel libxml2-devel libjpeg-devel libpng-devel openssl-devel curl-devel bison patch unzip libmcrypt-devel libmhash-devel ncurses-devel sudo bzip2 flex libaio-devel

二、?安裝cmake 編譯器

cmake 版本：cmake-3.1.1。

1、下載地址：http://www.cmake.org/files/v3.1/cmake-3.1.1.tar.gz

$ wget?http://www.cmake.org/files/v3.1/cmake-3.1.1.tar.gz

2、解壓安裝包

$ tar zxvf cmake-3.1.1.tar.gz

3、進入安裝包目錄

$ cd cmake-3.1.1

4、編譯安裝?

$ ./bootstrap $ make && make install

---

三、安裝 MySQL

MySQL版本：mysql-5.6.15。

1、下載地址：?http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.15.tar.gz

$ wget?http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.15.tar.gz

2、解壓安裝包

$ tar zxvf mysql-5.6.15.tar.gz

3、進入安裝包目錄

$ cd mysql-5.6.15

4、編譯安裝?

$ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/webserver/mysql/ -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DWITH_INNODB_MEMCACHED=1 -DWITH_DEBUG=OFF -DWITH_ZLIB=bundled -DENABLED_LOCAL_INFILE=1 -DENABLED_PROFILING=ON -DMYSQL_MAINTAINER_MODE=OFF -DMYSQL_DATADIR=/usr/local/webserver/mysql/data -DMYSQL_TCP_PORT=3306 $ make && make install

5、查看mysql版本:

$ /usr/local/webserver/mysql/bin/mysql --version

到此，mysql安裝完成。

MySQL 配置

1、創(chuàng)建mysql運行使用的用戶mysql：

$ /usr/sbin/groupadd mysql $ /usr/sbin/useradd -g mysql mysql

2、創(chuàng)建binlog和庫的存儲路徑并賦予mysql用戶權(quán)限

$ mkdir -p /usr/local/webserver/mysql/binlog /www/data_mysql $ chown mysql.mysql /usr/local/webserver/mysql/binlog/ /www/data_mysql/

3、創(chuàng)建my.cnf配置文件

將/etc/my.cnf替換為下面內(nèi)容

$ cat /etc/my.cnf[client] port = 3306 socket = /tmp/mysql.sock [mysqld] replicate-ignore-db = mysql replicate-ignore-db = test replicate-ignore-db = information_schema user = mysql port = 3306 socket = /tmp/mysql.sock basedir = /usr/local/webserver/mysql datadir = /www/data_mysql log-error = /usr/local/webserver/mysql/mysql_error.log pid-file = /usr/local/webserver/mysql/mysql.pid open_files_limit = 65535 back_log = 600 max_connections = 5000 max_connect_errors = 1000 table_open_cache = 1024 external-locking = FALSE max_allowed_packet = 32M sort_buffer_size = 1M join_buffer_size = 1M thread_cache_size = 600 #thread_concurrency = 8 query_cache_size = 128M query_cache_limit = 2M query_cache_min_res_unit = 2k default-storage-engine = MyISAM default-tmp-storage-engine=MYISAM thread_stack = 192K transaction_isolation = READ-COMMITTED tmp_table_size = 128M max_heap_table_size = 128M log-slave-updates log-bin = /usr/local/webserver/mysql/binlog/binlog binlog-do-db=oa_fb binlog-ignore-db=mysql binlog_cache_size = 4M binlog_format = MIXED max_binlog_cache_size = 8M max_binlog_size = 1G relay-log-index = /usr/local/webserver/mysql/relaylog/relaylog relay-log-info-file = /usr/local/webserver/mysql/relaylog/relaylog relay-log = /usr/local/webserver/mysql/relaylog/relaylog expire_logs_days = 10 key_buffer_size = 256M read_buffer_size = 1M read_rnd_buffer_size = 16M bulk_insert_buffer_size = 64M myisam_sort_buffer_size = 128M myisam_max_sort_file_size = 10G myisam_repair_threads = 1 myisam_recover interactive_timeout = 120 wait_timeout = 120 skip-name-resolve #master-connect-retry = 10 slave-skip-errors = 1032,1062,126,1114,1146,1048,1396 #master-host = 192.168.1.2 #master-user = username #master-password = password #master-port = 3306 server-id = 1 loose-innodb-trx=0? loose-innodb-locks=0? loose-innodb-lock-waits=0? loose-innodb-cmp=0? loose-innodb-cmp-per-index=0 loose-innodb-cmp-per-index-reset=0 loose-innodb-cmp-reset=0? loose-innodb-cmpmem=0? loose-innodb-cmpmem-reset=0? loose-innodb-buffer-page=0? loose-innodb-buffer-page-lru=0? loose-innodb-buffer-pool-stats=0? loose-innodb-metrics=0? loose-innodb-ft-default-stopword=0? loose-innodb-ft-inserted=0? loose-innodb-ft-deleted=0? loose-innodb-ft-being-deleted=0? loose-innodb-ft-config=0? loose-innodb-ft-index-cache=0? loose-innodb-ft-index-table=0? loose-innodb-sys-tables=0? loose-innodb-sys-tablestats=0? loose-innodb-sys-indexes=0? loose-innodb-sys-columns=0? loose-innodb-sys-fields=0? loose-innodb-sys-foreign=0? loose-innodb-sys-foreign-cols=0slow_query_log_file=/usr/local/webserver/mysql/mysql_slow.log long_query_time = 1 [mysqldump] quick max_allowed_packet = 32M

4、初始化數(shù)據(jù)庫

$/usr/local/webserver/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf ?--user=mysql

顯示如下信息：

Installing MySQL system tables...2015-01-26 20:18:51 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). OKFilling help tables...2015-01-26 20:18:57 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). OK ...

5、創(chuàng)建開機啟動腳本

$ cd /usr/local/webserver/mysql/ $ cp support-files/mysql.server /etc/rc.d/init.d/mysqld? $ chkconfig --add mysqld? $ chkconfig --level 35 mysqld on

6、啟動mysql服務(wù)器

$ service mysqld start

7、連接 MySQL

$ /usr/local/webserver/mysql/bin/mysql -u root -p

修改MySQL用戶密碼

mysqladmin -u用戶名 -p舊密碼 password 新密碼

或進入mysql命令行

SET PASSWORD FOR '用戶名'@'主機' = PASSWORD(‘密碼');

創(chuàng)建新用戶并授權(quán):

grant all privileges on *.* to 用戶名@'%' identified by '密碼' with grant option;

其他命令

• 啟動：service mysqld start
• 停止：service mysqld stop
• 重啟：service mysqld?restart
• 重載配置：service mysqld?reload
