• mysql安装配置


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

    MySQL所使用的SQL语言是用于访问数据库的最常用标准化语言。

    MySQL由于其体积小、速度快、总体拥有成本低,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、安装编译工具及库文件

    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

    mysql1

    2、解压安装包

    $ tar zxvf cmake-3.1.1.tar.gz

    3、进入安装包目录

    $ 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

    mysql2

    2、解压安装包

    $ tar zxvf mysql-5.6.15.tar.gz

    3、进入安装包目录

    $ 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

    mysql3

    到此,mysql安装完成。


    MySQL 配置

    1、创建mysql运行使用的用户mysql:

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

    2、创建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、创建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 = 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

    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、创建开机启动脚本

    $ 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

    mysql4

    7、连接 MySQL

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

    mysql5

    修改MySQL用户密码

    mysqladmin -u用户名 -p旧密码 password 新密码

    或进入mysql命令行

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

    创建新用户并授权:

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

    其他命令

    • 启动:service mysqld start
    • 停止:service mysqld stop
    • 重启:service mysqld restart
    • 重载配置:service mysqld reload
