  • linux系统安装mysql数据库

    1、首先关闭linux的防火墙,执行命令

    chkconfig iptables off

    2、从mysql官网上下载自己适合的mysql版本https://dev.mysql.com/downloads/mysql/5.6.html#downloads,进入mysql官网,依次点击

     

     

    3、下载后的mysql文件

    mysql-5.6.40-linux-glibc2.12-i686.tar.gz

     将下载好的mysql压缩文件放置在linux的/usr/local文件夹下,解压该压缩文件

     tar -zxvf mysql-5.6.40-linux-glibc2.12-i686.tar.gz

    将解压后的文件重命名为mysql

    mv mysql-5.6.40-linux-glibc2.12-i686 mysql

    4、创建mysql用户组及用户

    groupadd mysql
    useradd -r -g mysql mysql

    5、进入到mysql目录,执行添加MySQL配置的操作

    cp support-files/my-medium.cnf /etc/my.cnf
    或:
    cp support-files/my-default.cnf /etc/my.cnf
    是否覆盖?按y 回车

    6、编辑/etc/my.cnf文件;

    vi /etc/my.cnf

    在my.cnf文件中添加或者修改相关配置,更改完成后保存退出

    复制代码
     1 # For advice on how to change settings please see
     2 # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
     3 # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
     4 # *** default location during install, and will be replaced if you
     5 # *** upgrade to a newer version of MySQL.
     6 
     7 [mysqld]
     8 
     9 # Remove leading # and set to the amount of RAM for the most important data
    10 # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
    11 # innodb_buffer_pool_size = 128M
    12 
    13 # Remove leading # to turn on a very important data integrity option: logging
    14 # changes to the binary log between backups.
    15 # log_bin
    16 
    17 # These are commonly set, remove the # and set as required.
    18 basedir = /usr/local/mysql
    19 datadir = /usr/local/mysql/data
    20 port = 3306
    21 # server_id = .....
    22 socket = /tmp/mysql.sock
    23 character-set-server = utf8
    24 skip-name-resolve
    25 log-err = /usr/local/mysql/data/error.log
    26 pid-file = /usr/local/mysql/data/mysql.pid
    27 
    28 # Remove leading # to set options mainly useful for reporting servers.
    29 # The server defaults are faster for transactions and fast SELECTs.
    30 # Adjust sizes as needed, experiment to find the optimal values.
    31 # join_buffer_size = 128M
    32 # sort_buffer_size = 2M
    33 # read_rnd_buffer_size = 2M 
    34 
    35 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
    复制代码

    7、在mysql当前目录下设定目录的访问权限(注意后面的小点,表示当前目录)

    chown -R mysql .
    chgrp -R mysql .
    scripts/mysql_install_db --user=mysql
    chown -R root .
    chown -R mysql data

    8、初始化数据(在mysql/bin或者mysql/scripts下有个 mysql_install_db 可执行文件初始化数据库),进入mysql/bin或者mysql/scripts目录下,执行下面命令

    ./mysql_install_db --verbose --user=root --defaults-file=/etc/my.cnf --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql --pid-file=/usr/local/mysql/data/mysql.pid --tmpdir=/tmp

    9、启动mysql,进入/usr/local/mysql/bin目录,执行下面命令

    ./mysqld_safe --defaults-file=/etc/my.cnf --socket=/tmp/mysql.sock --user=root &
    注意,如果光标停留在屏幕上,表示启动成功,需要我们先关闭shell终端,再开启一个新的shell终端,不要执行退出操作。如果出现 mysql ended这样的语句,表示Mysql没有正常启动,你可以到log中查找问题. 

    10、设置开机启动,新开启shell中断后,进入mysql目录,执行下面命令

    复制代码
    cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
    cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql
    chmod 700 /etc/init.d/mysql
    chkconfig --add mysqld
    chkconfig --level 2345 mysqld on
    chown mysql:mysql -R /usr/local/mysql/
    复制代码

    重启linux

    reboot

    查看mysql状态

    service mysqld status

    11、添加远程访问权限

      (1)、添加mysql命令

    ln  -s /usr/local/mysql/bin/mysql  /usr/bin  (mysql的安装路径)

      (2)、更改访问权限

    登录mysql,执行下面命令
    mysql -uroot -p 
    密码为空直接回车,运行以下两条命令
    GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'duan' with grant option;
    Flush privileges;

    退出mysql

    exit

    重启linux,就完成了

    reboot

    注:本机访问mysql,root账户默认是没有密码的,端口号默认3306,如果需要修改root账户密码,在/usr/local/mysql/bin目录下,执行下面命令

    ./mysqladmin -h 127.0.0.1 -P3306 -uroot password 'duan'exit
