【第二章】MySQL数据库基于Centos7.3-安顿

发布时间:2019-09-06 07:39编辑:工作委员会浏览(171)

    一、MySQL数据库的官方网址:

    • https://www.oracle.com/
    • http://dev.mysql.com/doc/refman/5.7/en/linux-installation.html
    •        //不同版本的安装文档和下载可以在这里找

    Centos6源码部署MySQL5.6

    mysql从5.5版本开始,不再使用./configure编译,而是使用cmake编译器

    mysql-5.6.16.tar.gz源码包下载地址:

    我的mysql目录配置如下:
    安装路径:/usr/local/mysql
    数据库路径:/data/mysql
    源码包存放位置:/usr/software

    准备工作:安装基本依赖包,先用yum安装cmake、automake 、autoconf ,另MySQL 5.6.x需要最少安装的包有:bison,gcc、gcc-c++、ncurses-devel
    [[email protected] ~]# yum install cmake make -y
    [[email protected] ~]# yum install gcc gcc-c++ autoconf bison automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel* -y
    [[email protected] ~]# cp /root/mysql-5.6.15.tar.gz /usr/software/
    [[email protected] ~]# cd /usr/software
    开始编译安装
    [[email protected] ~]# tar -zxvf mysql-5.6.15.tar.gz
    [[email protected] ~]# cd mysql-5.6.15
    [[email protected] ~]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql
    -DMYSQL_UNIX_ADDR=/data/mysql/mysql.sock
    -DDEFAULT_CHARSET=utf8
    -DDEFAULT_COLLATION=utf8_general_ci
    -DWITH_EXTRA_CHARSETS:STRING=utf8,gbk
    -DWITH_INNOBASE_STORAGE_ENGINE=1
    -DWITH_READLINE=1
    -DENABLED_LOCAL_INFILE=1
    -DMYSQL_DATADIR=/data/mysql/
    -DMYSQL_USER=mysql
    -DMYSQL_TCP_PORT=3306
    [[email protected] ~]# make && make install

    mysql官网英文文档简单翻译说明一下
    The MyISAM, MERGE, MEMORY, and CSV engines are mandatory (always compiled into the server) and need not be installed explicitly.(说明:mysql默认支持的数据库引擎有MyISAM, MERGE, MEMORY, CSV,无需在编译时再声明)
    所以上面的编译条件省掉了如下两行
    -DWITH_MYISAM_STORAGE_ENGINE=1
    -DWITH_MEMORY_STORAGE_ENGINE=1
    但INNODB一定要声明式安装,所以多了这一行
    -DWITH_INNOBASE_STORAGE_ENGINE=1

    查看mysql.mysql的用户及组是否存在

    [[email protected] ~]# cat /etc/passwd |grep mysql

    mysql:x:501:503::/home/mysql:/bin/bash

    [[email protected] ~]# cat /etc/group |grep mysql

    mysql:x:503:

    不OK就执行以下两行命令(否则跳过这一步)
    [[email protected] ~]# groupadd mysql #添加mysql用户组
    [[email protected] ~]# useradd mysql -g mysql -s /sbin/nologin # 添加mysql用户

    以下带红色字体的命令非常非常,必须要执行
    [[email protected] ~]# cd /usr/local/mysql
    [[email protected] ~]# chown mysql.mysql -R . #将mysql目录赋予mysql用户的执行权限
    [[email protected] ~]# chown mysql.mysql -R /data/mysql
    [[email protected] ~]# cp support-files/my-default.cnf /etc/my.cnf #mysql配置文件
    [[email protected] ~]# chmod 755 scripts/mysql_install_db #赋予mysql_install_db执行权限

    以下命令为mysql 启动及自启动配置
    [[email protected] ~]# scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql/

    输出如下信息:

    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/mysql/bin/mysqladmin -u root password 'new-password'

    /usr/local/mysql/bin/mysqladmin -u root -h ziteng26 password 'new-password'

     

    Alternatively you can run:

     

    /usr/local/mysql/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/mysql/bin/mysqld_safe &

     

    You can test the MySQL daemon with mysql-test-run.pl

     

    cd mysql-test ; perl mysql-test-run.pl

     

    Please report any problems with the ./bin/mysqlbug script!

     

    The latest information about MySQL is available on the web at

     

     

    Support MySQL by buying support/licenses at

     

    New default config file was created as /usr/local/mysql/my.cnf and

    will be used by default by the server when you start it.

    You may edit this file to change server settings

     

    WARNING: Default config file /etc/my.cnf exists on the system

    This file will be read by default by the MySQL server

    If you do not want to use this, either remove it, or use the

     

    --defaults-file argument to mysqld_safe when starting the server

     

    [[email protected] ~]# cp support-files/mysql.server /etc/init.d/mysqld
    [[email protected] ~]# chmod 755 /etc/init.d/mysqld
    查看mysqld服务是否设置为开机启动
    [[email protected] ~]# chkconfig --list|grep mysqld
    设置为开机启动
    [[email protected] ~]# chkconfig mysqld on

    启动mysql数据库,会输出一系列有用的信息,告诉你接下去如何初始化mysql

    [[email protected] mysql]# service mysqld start

    按照上述英文,我们来初始化管理员root的密码

    [[email protected] ~]# /usr/local/mysql/bin/mysqladmin -u root password 'yourpassword'

    此处yourpassword设置为 manager

     

     

    众所周知,mysql有两种帐号类型,即localhost和%,前者限本机连接mysql,后者可用于其它机器远程连接mysql

    最后,处理帐号登录问题,让root帐号密码可以本地和远程连接使用

    [[email protected] ~]# /usr/local/mysql/bin/mysql -u root -p #敲入该命令后,屏幕会提示输入密码,输入上一步设置的yourpassword

    删除root密码为空的记录

    mysql> use mysql;

    mysql> delete from user where password='';

    mysql> flush privileges;

    配置mysql允许root远程登录 #登录

    mysql> grant all privileges on *.* to [email protected]'%' identified by "manager";

    mysql> flush privileges;

    mysql> select User,Password,Host from user;

     

    上述命令如果执行成功

     

    mysql> quit

     

     

    至此,mysql安装已经全部结束.

     

    mysql从5.5版本开始,不再使用./configure编译,而是使用cmake编译器 mysql-5.6.16.tar.gz源码包下载地址: ...

    二、MySQL的安装方法:

    以下是MySQL常见的三种安装方式:

    • 二进制  rpm   Yum Repository    mysql57-community-release-el7-9.noarch.rpm
    • 二进制  预编译  Generic                        mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz
    • 源码包安             Source Code                mysql-5.7.19.tar.gz
