Linux安装64位Mysql5.7.22

 转自https://www.cnblogs.com/jxrichar/p/9248480.html

以安装在/usr/local目录下为例

1.下载安装包地址:https://dev.mysql.com/downloads/file/?id=476936,安装包保存到/usr/local

2.解压:

cd /usr/local

tar -zxvf mysql-5.7.22-linux-glibc2.12-x86_64.tar

mv mysql-5.7.22-linux-glibc2.12-x86_64 mysql-5.7.22

3.添加用户组和用户

#添加用户组
groupadd mysql
#添加用户mysql 到用户组mysql
useradd -g mysql mysql

4.安装

cd /usr/local/mysql-5.7.22

mkdir data

chown -R mysql:mysql ./

./bin/mysqld –-initialize --user=mysql --basedir=/usr/local/mysql-5.7.22/ --datadir=/usr/local/mysql-5.7.22/data/

#将mysql/目录下除了data/目录的所有文件,改回root用户所有
chown -R root .
#mysql用户只需作为mysql-5.7.20/data/目录下所有文件的所有者
chown -R mysql data

5.复制启动文件

cp support-files/mysql.server /etc/init.d/mysqld

chmod 755 /etc/init.d/mysqld

cp /bin/my_print_defaults /usr/bin/ 

6.修改启动脚本

vi /etc/init.d/mysqld
#修改项:
basedir=/usr/local/mysql-5.7.20/
datadir=/usr/local/mysql-5.7.20/data
port=3306

#加入环境变量,编辑 /etc/profile,这样可以在任何地方用mysql命令了
vi /etc/profile
#添加mysql路径,加入下面内容,按ESC-->:wq保存
export PATH=$PATH:/usr/local/mysql-5.7.20/bin
#刷新立即生效
source /etc/profile

7.修改mysql配置项

vi /etc/my.cnf

配置如下:

[mysqld]
basedir = /usr/local/mysql-5.7.22
datadir = /usr/local/mysql-5.7.22/data
socket = /tmp/mysql.sock
user = mysql
tmpdir = /tmp
symbolic-links=0

[mysqld_safe]

log-error = /usr/local/mysql-5.7.22/data/error.log
pid-file = /usr/local/mysql-5.7.22/data/mysql.pid
!includedir /etc/my.cnf.d

 8.启动mysql

service mysqld start

如启动失败,删除 /usr/local/mysql-5.7.22/data下所有文件,重新执行./bin/mysqld –-initialize --user=mysql --basedir=/usr/local/mysql-5.7.22/ --datadir=/usr/local/mysql-5.7.22/data/,再启动

9.进入mysql修改初始密码,修改远程连接的用户权限问题

mysql -uroot -p

 

ALTER USER USER() IDENTIFIED BY '123';

use mysql;

update user set host = '%' where user ='root';

flush privileges;
