本篇內容主要講解“5.7.17版本的安裝步驟”，感興趣的朋友不妨來(lái)看看。本文介紹的方法操作簡(jiǎn)單快捷，實(shí)用性強。下面就讓小編來(lái)帶大家學(xué)習“MYSQL5.7.17版本的安裝步驟”吧!

MYSQL 5.7.17 安裝：

• 軟件獲?。?

官網(wǎng)下載mysql-advanced-5.7.17-linux-glibc2.5-x86_64.tar.gz

• 解壓安裝：

解壓mysql-advanced-5.7.17-linux-glibc2.5-x86_64.tar.gz

tar -xvzf mysql-advanced-5.7.17-linux-glibc2.5-x86_64.tar.gz

將解壓的安裝文件拷貝到安裝目錄（可自定義）

[root@VMOS01 mysql]# cp -r mysql-advanced-5.7.17-linux-glibc2.5-x86_64 /usr/local/

[root@VMOS01 mysql]# cd /usr/local

[root@VMOS01 local]# mv mysql-advanced-5.7.17-linux-glibc2.5-x86_64 mysql-5.7.17

• 建立軟鏈接：

[root@VMOS01 local]# ln -s mysql-5.7.17 mysql

[root@VMOS01 local]# ln -s /usr/local/mysql/bin/mysql  /usr/bin/mysql

• 添加MYSQL 運行用戶(hù)：

[root@VMOS01 local]# useradd -r -M -u 496 -s /sbin/nologin mysql

將軟件、目錄賦權給運行用戶(hù)mysql:

[root@VMOS01 local]# chown -R mysql.mysql /usr/local/mysql-5.7.17/

[root@VMOS01 local]# chown -R mysql.mysql /usr/local/mysql

[root@VMOS01 local]# chgrp -R mysql /usr/local/mysql-5.7.17/

• 初始化mysql db:

[root@VMOS01 local]# cd /usr/local/mysql

[root@VMOS01 bin]# cd ..

[root@VMOS01 mysql]# ./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/

2017-04-09 22:38:11 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize

2017-04-09 22:38:20 [WARNING] The bootstrap log isn't empty:

2017-04-09 22:38:20 [WARNING] 2017-04-10T05:38:12.530858Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead

mysql5.7新特性：由上面可以看出， mysql_install_db 已經(jīng)不再推薦使用了，建議改成 mysqld --initialize 完成實(shí)例初始化。

[root@VMOS01 mysql]# ./bin/mysqld --defaults-file=/etc/my.cnf --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/  --initialize

2017-04-10T06:12:09.706181Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

2017-04-10T06:12:11.269373Z 0 [Warning] InnoDB: New log files created, LSN=45790

2017-04-10T06:12:11.496771Z 0 [Warning] InnoDB: Creating foreign key constraint system tables.

2017-04-10T06:12:11.564642Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: a27f16b1-1db4-11e7-b5f3-000c2993673d.

2017-04-10T06:12:11.566539Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened.

2017-04-10T06:12:12.196832Z 0 [Warning] CA certificate ca.pem is self signed.

2017-04-10T06:12:12.439938Z 1 [Note] A temporary password is generated for root@localhost: S8t6ikvw<t1E 【記住初始密碼】

• 啟動(dòng)mysql：

[root@VMOS01 support-files]# ./mysql.server start

Starting MySQL SUCCESS!

***

• 將mysql添加到系統服務(wù)管理：

[root@VMOS01 support-files]# cp -v mysql.server /etc/init.d

`mysql.server' -> `/etc/init.d/mysql.server'

[root@VMOS01 support-files]# cd /etc/init.d

[root@VMOS01 init.d]# chkconfig --add mysql.server

[root@VMOS01 init.d]# service mysql.server status

SUCCESS! MySQL running (33215)

[root@VMOS01 init.d]# service mysql.server stop

Shutting down MySQL.. SUCCESS!

[root@VMOS01 init.d]# service mysql.server start

Starting MySQL. SUCCESS!

• 注意點(diǎn)：

編輯my.cnf 讓本地命令行登陸管理mysql， 不會(huì )提示找不到mysql.sock文件錯誤：

[root@VMOS01 mysql]# more /etc/my.cnf

[client]

socket=/var/lib/mysql/mysql.sock

[root@VMOS01 init.d]# mysql -uroot -p

Enter password: 【輸入初始DB的密碼】

**************************

• 需要更改root@localhost初始密碼：

第一次登陸mysql,需要更改root@localhost密碼，否則會(huì )出現如下錯誤：

[root@VMOS01 support-files]# mysql -ur0ot -p

Enter password:

mysql> show databases;

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

mysql> alter user root@localhost identified by "Root15()";

mysql> show databases;

至此mysql 5.7.17安裝完成。
