MySQL的安装分为三种：

1、RPM包安装；

2、二进制包安装；

3、源码安装。

第一种方式比较简单，直接RPM包安装就OK了，或者通过yum源来安装，但无法自定义安装目录。

而第三种方式比较复杂。

一般项目中使用比较多的是通过二进制包来安装，这种安装方式可以根据企业的不同需求进行相关的自定义配置，比如安装在哪个目录，如何配置等。

MySQL5.7与5.6安装有所改变。

CentOS版本

[mysql@new ~]$ cat /etc/redhat-release

CentOS release 6.3 (Final)

[mysql@new ~]$

把安装文件上传至服务器

[mysql@new ~]$ ls

重命名目录

[mysql@guoqing ~]$ mv mysql-5.7.10-linux-glibc2.5-x86_64 mysql

[mysql@guoqing ~]$ ls

mysql  mysql-5.7.10-linux-glibc2.5-x86_64.tar.gz

[mysql@guoqing ~]$ cd mysql

[mysql@guoqing mysql]$ ls

新建存放数据的目录data

[mysql@guoqing mysql]$ mkdir data

拷贝my.cnf文件

[mysql@guoqing mysql]$ su

Password:

[root@guoqing mysql]# cp support-files/my-default.cnf /etc/

[root@guoqing mysql]# chown mysql.mysql /etc/my.cnf

拷贝MySQL服务文件

[root@guoqing mysql]# cp support-files/mysql.server /etc/init.d/mysql

在MySQL服务文件中把/usr/local/指替换成自己安装MySQL目录

这里是替换成的home/mysql

[root@guoqing mysql]# vi /etc/init.d/mysql# 0 means don't wait at all

# Negative numbers mean to wait indefinitely

service_startup_timeout=900

# Lock directory for RedHat / SuSE.

lockdir='/var/lock/subsys'

lock_file_path="$lockdir/mysql"

# The following variables are only set for letting mysql.server find things.

# Set some defaults

mysqld_pid_file_path=

if test -z "$basedir"

then

basedir=/home/mysql/mysql

bindir=/home/mysql/mysql/bin

if test -z "$datadir"

then

datadir=/home/mysql/mysql/data

fi

sbindir=/home/mysql/mysql/bin

libexecdir=/home/mysql/mysql/bin

else

bindir="$basedir/bin"

if test -z "$datadir"

then

datadir="$basedir/data"

fi

sbindir="$basedir/sbin"

libexecdir="$basedir/libexec"

fi

# datadir_set is used to determine if datadir was set (and so should be

# *not* set inside of the --basedir= handler.)

datadir_set=

#

# Use LSB init script functions for printing messages, if possible

#

lsb_functions="/lib/lsb/init-functions"

if test -f $lsb_functions ; then

. $lsb_functions

else

"/etc/rc.d/init.d/mysql" 393L, 10981C written

[root@guoqing mysql]# exit

exit

修改my.cnf文件，主要添加basedir、datadir

[mysql@guoqing mysql]$ vi /etc/my.cnf

[mysqld]

basedir=/home/mysql/mysql

datadir=/home/mysql/mysql/data

socket=/home/mysql/mysql/mysql.sock

user=mysql

# Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

[mysqld_safe]

log-error=/home/mysql/mysql/data/mysqld.log

pid-file=/home/mysql/mysql/data/mysqld/mysqld.pid

"/etc/my.cnf" 11L, 316C written

初始化MySQL

MySQL 5.7.6之后版本为 ./bin/mysqld --initialize --user=mysql --basedir=/home/mysql/mysql --datadir=/home/mysql/mysql/data/

[mysql@guoqing mysql]$ ./bin/mysqld --initialize --user=mysql --basedir=/home/mysql/mysql --datadir=/home/mysql/mysql/data/

添加环境变量:/home/mysql/mysql/bin

[mysql@guoqing ~]$ vi .bash_profile

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

# User specific environment and startup programs

export PATH

使变量生效[mysql@guoqing ~]$ . .bash_profile

启动MySQL服务[mysql@new ~]$ service mysql start

Starting MySQL.                                            [  OK  ]

登录

用到上面日志中的密码，注意qnW8usF=o;=e全是密码内容

[mysql@guoqing ~]$ mysql -uroot  -p

Enter password:

修改密码

至此，MySQL5.7.10安装完成，整体与5.6安装差别不大，便要注意root密码的长度，初始化方式等。
