RHEL6.6下MySQL8.0安装配置初体验

MySQL8.0的官方社区开源版出来有段时间了，而percona的8.0版本还没有正式对外发布（已发布测试版），一直以来也没安装体验下这个号称质的飞跃的版本，今天正好有些时间就下了安装体验体验。

一、MySQL8.0下载

下载地址：https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.13-linux-glibc2.12-x86_64.tar.xz

二、安装环境

三、MySQL8.0安装

官方参考：https://dev.mysql.com/doc/refman/8.0/en/binary-installation.html

1.软件下载

[root@node tools]# wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.13-linux-glibc2.12-x86_64.tar.xz

2.依赖包安装

[root@node mysql]# yum search libaio [root@node mysql]# yum install libaio 3.用户创建 [root@node mysql]# groupadd mysql [root@node mysql]# useradd -r -g mysql -s /bin/false mysql

4.解压缩安装包

[root@node mysql]# cd /usr/local [root@node mysql]# tar -xvf mysql-8.0.13-linux-glibc2.12-x86_64.tar.xz

5.规划软件和数据文件目录 [root@node tools]# mv mysql-8.0.13-linux-glibc2.12-x86_64 /usr/local/mysql [root@node mysql]# cd /usr/local/mysql [root@node mysql]# mkdir -p /data/mysql/data

6.修改属主权限 [root@node mysql]# chown -R mysql:mysql /data/mysql/data [root@node mysql]# chmod -R 750 /data/mysql/data

7.数据库初始化 [root@node mysql]# bin/mysqld --initialize --user=mysql  --datadir=/data/mysql/data 2018-11-12T02:49:23.293863Z 0 [System] [MY-013169] [Server] /usr/local/mysql/bin/mysqld (mysqld 8.0.13) initializing of server in progress as process 24839 2018-11-12T02:49:26.840424Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: Vxxx1n%Mj7uZ 2018-11-12T02:49:29.671663Z 0 [System] [MY-013170] [Server] /usr/local/mysql/bin/mysqld (mysqld 8.0.13) initializing of server has completed

8.ssl部署 [root@node mysql]# bin/mysql_ssl_rsa_setup Generating a 2048 bit RSA private key .......+++ ............................+++ writing new private key to 'ca-key.pem' ----- Generating a 2048 bit RSA private key ...........................................+++ ..+++ writing new private key to 'server-key.pem' ----- Generating a 2048 bit RSA private key ..................................................................+++ ...................+++ writing new private key to 'client-key.pem' -----

9.启动数据库 [root@node mysql]# bin/mysqld_safe --user=mysql --datadir=/data/mysql/data & [1] 25195 [root@node mysql]# Logging to '/data/mysql/data/node.err'. 2018-11-12T02:51:59.390239Z mysqld_safe Starting mysqld daemon with databases from /data/mysql/data

10.连接数据库 [root@node mysql]# mysql -uroot -p'Vjk01n%Mj7uZ'  -hlocalhost

mysql> select user,host from mysql.user; ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

11.修改数据库初始密码

mysql> alter user root@'localhost' identified by 'xxxx'; Query OK, 0 rows affected (0.07 sec)

12.数据库查询 mysql> select user,host from mysql.user;    +------------------+-----------+ | user            | host      | +------------------+-----------+ | mysql.infoschema | localhost | | mysql.session    | localhost | | mysql.sys        | localhost | | root            | localhost | +------------------+-----------+ 4 rows in set (0.00 sec)

13.MySQL启动服务配置 [root@node mysql]# cp -rp support-files/mysql.server  /etc/init.d/mysqld

[root@node data]# chkconfig  --add mysqld [root@node mysql]# vi /etc/my.cnf

[root@node ~]# vi /root/.bash_profile PATH=PATH:HOME/bin:/usr/local/sysbench/bin:/usr/local/mysql/bin/[root@node ~]# source ~/.bash_profile

14.杀掉MySQL进程，通过service服务重启数据库 [root@node data]# service mysqld start Starting MySQL..................                          [  OK  ]

至此MySQL8.0二进制包数据库安装完毕，开始体验其功能。
