安装包下载
MySQL 的官网下载地址:http://www.mysql.com/downloads/
我安装的是5.7版本
第二步:
选择:TAR
(mysql-5.7.24-el7-x86_64.tar) 点击下载
然后点击 No thanks, just start my download. 进行下载。
检查是否安装过mysql
[root@master mysql]# rpm -qa|grep mysql
mysql-community-common-5.7.10-1.el7.x86_64
mysql-community-libs-5.7.10-1.el7.x86_64
mysql-community-server-5.7.10-1.el7.x86_64
qt-mysql-4.8.5-13.el7.x86_64
mysql-community-client-5.7.10-1.el7.x86_64
下载已经安装
[root@master mysql]# rpm -e --nodeps mysql-community-common-5.7.10-1.el7.x86_64
[root@master mysql]# rpm -e --nodeps mysql-community-common-5.7.10-1.el7.x86_64
[root@master mysql]# rpm -e --nodeps mysql-community-libs-5.7.10-1.el7.x86_64
[root@master mysql]# rpm -e --nodeps mysql-community-server-5.7.10-1.el7.x86_64
[root@master mysql]# rpm -e --nodeps qt-mysql-4.8.5-13.el7.x86_64
[root@master mysql]# rpm -e --nodeps mysql-community-client-5.7.10-1.el7.x86_64
再次查看
[root@master mysql]# rpm -qa|grep mysql
[root@master mysql]#
查看是否按照自带的mariadb数据库
[root@master mysql]# rpm -qa|grep -i mariadb
5.MySQL的server端需要Perl支持,安装一下
[root@master mysql]# yum install perl -y
检查mysql组和用户
是否存在,如无创建:
[root@master mysql]# cat /etc/group | grep mysql
[root@master mysql]# cat /etc/passwd |grep mysql
[root@master mysql]# groupadd mysql
[root@master mysql]# useradd -r -g mysql mysql
放置安装包
从官网下载mysql安装包,解压后移动到/usr/local/mysql下
[root@master mysql]# ls
bin COPYING COPYING-test data docs include lib man mysql-test README README-test share support-files
创建数据目录data
mkdir -p /usr/local/mysql/data
cd /usr/local
chown -R mysql:mysql mysql/
chmod -R 755 mysql/
安装初始化MySQL
[root@master bin]# /usr/local/mysql/mysql/bin/mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data --basedir=/usr/local/mysql 2019-01-03T04:39:31.511114Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

启动MySQL服务
[root@master ~]# /usr/local/mysql/support-files/mysql.server start
Starting MySQL. SUCCESS!
[root@master ~]#
做个软连接重启服务
ln -s /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
[root@master ~]# service mysql restart
Shutting down MySQL.. SUCCESS!
Starting MySQL. SUCCESS!
[root@master ~]#
做个软链接,将安装目录下的mysql 放在/usr/bin 目录下
[root@master ~]# ln -s /usr/local/mysql/bin/mysql /usr/bin
修改密码,开放远程
[root@master ~]# mysql -u root -p Enter password: Server version: 5.7.24 Type 'help;' or 'h' for help. Type 'c' to clear the current input statement. mysql> alter user 'root'@'localhost' identified by 'mysql'; Query OK, 0 rows affected (0.00 sec) mysql> use mysql; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> update user set user.Host='%' where user.User='root'; Query OK, 1 row affected (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql>
