MySQL 是最流行的关系型数据库治理系统,由瑞典MySQL AB公司开发,目前属于Oracle公司.

MySQL所使用的SQL语言是用于拜访数据库的最常用标准化语言.

MySQL由于其体积小、速度快、总体拥有本钱低,尤其是开放源码这一特点,一般中小型网站的开发都选择MySQL作为网站数据库.

MySQL 安装

本教程的系统平台：CentOS release 6.6 (Final) 64位.

一、安装编译对象及库文件

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、 安装cmake 编译器

cmake 版本：cmake-3.1.1.

1、下载地址：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、解压安装包

$ tar zxvf cmake-3.1.1.tar.gz

3、进入安装包目次

$ cd cmake-3.1.1

4、编译安装

$ ./bootstrap

$ make && make install

三、安装 MySQL

MySQL版本：mysql-5.6.15.

1、下载地址： 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、解压安装包

$ tar zxvf mysql-5.6.15.tar.gz

3、进入安装包目次

$ cd mysql-5.6.15

4、编译安装

$ 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安装完成.

MySQL 设置装备摆设

1、创立mysql运行使用的用户mysql：

$ /usr/sbin/groupadd mysql

$ /usr/sbin/useradd -g mysql mysql

2、创立binlog和库的存储路径并赋予mysql用户权限

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

$ chown mysql.mysql /usr/local/webserver/mysql/binlog/ /www/data_mysql/

3、创立my.cnf配置文件

将/etc/my.cnf替换为下面内容

$ 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 = 2kdefault-storage-engine = MyISAMdefault-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

slow_query_log_file=/usr/local/webserver/mysql/mysql_slow.log

long_query_time = 1[mysqldump]

quick

max_allowed_packet = 32M

4、初始化数据库

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

显示如下信息：

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).

OK

Filling 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、创立开机启动脚本

$ 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、启动mysql服务器

$ service mysqld start

7、衔接 MySQL

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

修改MySQL用户暗码

mysqladmin -u用户名 -p旧暗码 password 新暗码

或进入mysql命令行

SET PASSWORD FOR '用户名'@'主机' = PASSWORD(‘暗码');

创建新用户并授权:

grant all privileges on *.* to 用户名@'%' identified by '暗码' with grant option;

其他命令

·启动：service mysqld start

·结束：service mysqld stop

·重启：service mysqld restart

·重载设置装备摆设：service mysqld reload
