开网站做销售,全景网站如何做,最新消息今天的新闻,网站开发与实训报告以下安装方式，在阿里云与腾讯云服务器上都测试可用。一、进入到opt目录下，执行： [rootmaster opt]# wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz解压： [rootmaster opt]#…

以下安装方式，在阿里云与腾讯云服务器上都测试可用。
一、进入到opt目录下，执行：

[root@master opt]# wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz

解压：

[root@master opt]# tar -xvf mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz

修改名字：

[root@master opt]# mv mysql-5.7.26-linux-glibc2.12-x86_64/ mysql-5.7.26

移动到/usr/local

[root@master opt]# mv mysql-5.7.26 /usr/local/

创建mysql用户组和用户：

[root@master opt]# groupadd mysql
[root@master opt]# useradd -r -g mysql mysql

进入/usr/local/mysql-5.7.26/目录下，创建一个/data/mysql目录

[root@master opt]# cd /usr/local/mysql-5.7.26/
[root@master opt]# mkdir data
[root@master opt]# cd data/
[root@master opt]# mkdir mysql

对该目录进行授权设置：

[root@master opt]# chown mysql:mysql -R ../data/mysql/

设置vim /etc/my.cnf参数

[mysqld]
bind-address=xxx.xxx.xxx.xxx
port=3306
user=mysql
basedir=/usr/local/mysql-5.7.26
datadir=/usr/local/mysql-5.7.26/data/mysql
socket=/tmp/mysql.sock
log-error=/usr/local/mysql-5.7.26/data/mysql/mysql.err
pid-file=/usr/local/mysql-5.7.26/data/mysql/mysql.pid
#character config
character_set_server=utf8
symbolic-links=0[client]
socket=/tmp/mysql.sock

初始化mysql:

进入到/usr/local/mysql-5.7.26/bin目录，执行

[root@master opt]# ./mysqld --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql-5.7.26/ --datadir=/usr/local/mysql-5.7.26/data/mysql/ --user=mysql --initialize

获取初始化生成的密码：zuN4F%E)R!q3

[root@master bin]# cat /usr/local/mysql-5.7.26/data/mysql/mysql.err

先进入/usr/local/mysql-5.7.26/support-files目录，看到有mysql.server脚本——

[root@master mysql-5.7.26]# pwd
/usr/local/mysql-5.7.26
[root@master mysql-5.7.26]# ll

-rwxr-xr-x 1 7161 31415 10576 Apr 13  2019 mysql.server

启动执行：

[root@master support-files]# ./mysql.server start
Starting MySQL.                                            [  OK  ]

然后切换到/usr/local/mysql-5.7.26/bin目录，执行进入mysql的指令：

[root@master bin]# ./mysql -u root -p

最后，就是修改密码操作了：

mysql> SET PASSWORD = PASSWORD('xxx');
Query OK, 0 rows affected, 1 warning (0.00 sec)mysql> ALTER USER 'xxx'@'localhost' PASSWORD EXPIRE NEVER;
Query OK, 0 rows affected (0.00 sec)mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

设置远程访问：

mysql> grant all on *.* to xxx@'%' identified by 'xxx' with grant option; 
Query OK, 0 rows affected, 1 warning (0.00 sec)mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

设置开机启动：

先将/usr/local/mysql-5.7.26/support-files/ 文件夹下的mysql.server文件复制到 /etc/rc.d/init.d/ 目录下

[root@master init.d]# cp /usr/local/mysql-5.7.26/support-files/mysql.server /etc/rc.d/init.d/
[root@master init.d]# ll
total 40
-rwxr-xr-x  1 root root  2415 Jun 30 21:19 aegis

-rwxr-xr-x  1 root root 10576 Oct 20 16:23 mysql.server
-rw-r--r--. 1 root root  1161 Mar 23  2021 README

将mysql.server修改为mysqld

[root@master init.d]# mv mysql.server mysqld

添加为服务: chkconfig --add mysqld

查看服务列表: chkconfig --list

[root@master init.d]#  chkconfig --listNote: This output shows SysV services only and does not include nativesystemd services. SysV configuration data might be overridden by nativesystemd configuration.If you want to list systemd services use 'systemctl list-unit-files'.To see services enabled on particular target use'systemctl list-dependencies [target]'.aegis          	0:off	1:off	2:on	3:on	4:on	5:on	6:off
jexec          	0:off	1:on	2:on	3:on	4:on	5:on	6:off
mysqld         	0:off	1:off	2:on	3:on	4:on	5:on	6:off

3、4、5状态为 on 则表示设置开机启动成功。
