mysql 5.7.14二進位包安裝

標籤：二進位   mysql   作業系統   

作業系統版本：

[[email protected] ~]# cat /etc/redhat-release

CentOS release 6.5 (Final)

作業系統核心：

[[email protected] ~]# uname -r

2.6.32-431.el6.x86_64

關閉防火牆並關閉自啟動：

[[email protected] ~]# /etc/init.d/iptables stop

[[email protected] ~]# chkconfig --level 2345 iptables off

臨時禁用selinux，並修改設定檔重啟系統也禁用：

[[email protected] ~]# setenforce 0

[[email protected] ~]# vim /etc/sysconfig/selinux

SELINUX=disabled

建立目錄，把mysql二進位包上傳到此目錄下：

[[email protected] ~]# mkdir -p /home/tools

切換到目錄下，解壓二進位包：

[[email protected] ~]# cd /home/tools/

[[email protected] tools]# tar zxf mysql-5.7.14-linux-glibc2.5-x86_64.tar.gz

建立解壓包的軟連結，建立軟串連的目的主要是方便以後升級：

[[email protected] tools]# ln -s /home/tools/mysql-5.7.14-linux-glibc2.5-x86_64  /usr/local/mysql

建立使用者組和使用者：

[[email protected] local]# groupadd mysql     

[[email protected] local]# useradd -M -g mysql -s /sbin/nologin -d /usr/local/mysql/ mysql

建立mysql資料，日誌，臨時等目錄，並修改所有者和所屬組：

[[email protected] local]# mkdir -p /data/mysql/mysql3306/data /data/mysql/mysql3306/log /data/mysql/mysql3306/tmp

[[email protected] local]# chown -R mysql:mysql /data/mysql/mysql3306/

修改/etc/my.cnf檔案，使用預設my.cnf的也可以初始化成功，不過一些檔案的位置會有點亂，這雷根據個人習慣修改如下：

[[email protected] tools]# vim /etc/my.cnf

[client]

port            = 3306

socket          = /tmp/mysql.sock

[mysql]

prompt="\\[email protected]\\h [\\d]>"

資料庫初始化，預設是帶密碼的，也可以指定參數--initialize-insecure則不要求輸入密碼

[[email protected] data]# cd /usr/local/mysql/bin/   

[[email protected] bin]# ./mysqld --initialize --user=mysql

查看密碼：

[[email protected] data]# cat /data/mysql/mysql3306/data/error.log |grep password

2016-11-17T13:29:25.055578Z 1 [Note] A temporary password is generated for [email protected]: XgqTE9Cb+rLc

複製啟動指令碼並改名為mysql：

[[email protected] init.d]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql

啟動mysql服務，並加入自啟動中：

[[email protected] init.d]# /etc/init.d/mysql start

[[email protected] ~]# chkconfig --add mysql

執行命令加入環境變數：

echo ‘export PATH=$PATH:/usr/local/mysql/bin/‘>>/etc/profile

[[email protected] init.d]# source /etc/profile

[[email protected] init.d]# mysql -S /tmp/mysql.sock -p

Enter password:   --寫入上面查看到的密碼

立即修改使用者密碼：

unknown)@localhost [(none)]>alter user user() identified by ‘147258‘;

查看資料庫帳號，5.7中user表中帳號比較安全，不需要帳號安全強化，即不需要刪除無用帳號

[email protected] [(none)]>select user,host from mysql.user;

+-----------+-----------+

| user      | host      |

+-----------+-----------+

| mysql.sys | localhost |

| root      | localhost |

+-----------+-----------+
