Linux下安装MySQL8.0.11的教程

1. 去官网下载安装包

下载链接：点击打开链接

如果你的系统是32位选择第一个，64位选择第二个

也可以用wget 下载

wget https://dev.mysql.com/get/downloads/mysql-8.0/mysql-8.0.11-linux-glibc2.12-i686.tar.gz

解压文件

tar -zxvf mysql-8.0.11-linux-glibc2.12-i686.tar.gz

2 移动压缩包到usr/local目录下,并重命名文件

mv /root/mysql-8.0.11-linux-glibc2.12-i686 /usr/local/mysql

3.在mysql根目录下新建一个文件夹data,用于存放数据

mkdir data

4.创建 mysql 用户组和 mysql 用户

groupadd mysql
useradd -g mysql mysql

5.改变 mysql 目录权限

chown -r mysql.mysql /usr/local/mysql/
 
或者
 
chown -r mysql .
 
chgrp -r mysql .

注意最后有一点

6.初始化数据库

创建mysql_install_db安装文件

mkdir mysql_install_db
chmod 777 ./mysql_install_db

初始化

bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data //初始化数据库

或者

/usr/local/mysql/bin/mysqld --initialize --user=mysql
/usr/local/mysql/bin/mysqld --initialize --user=mysql
/usr/local/mysql/bin/mysqld (mysqld 8.0.11) initializing of server in progress as process 5826
 [server] a temporary password is generated for root@localhost: twi=tlsi<0o!
/usr/local/mysql/bin/mysqld (mysqld 8.0.11) initializing of server has completed

记录好自己的临时密码：

twi=tlsi<0o!

这里遇到了问题没有libnuma.so.1

zsh: command not found: mysqld
./bin/mysqld --initialize
./bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: no such file or directory

2018-04-29 17:06:30 [warning] mysql_install_db is deprecated. please consider switching to mysqld --initialize
2018-04-29 17:06:30 [error] can't locate the language directory.

需要安装 libnuma

yum install libnuma
yum -y install numactl
yum install libaio1 libaio-dev

安装文件

7.mysql配置

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

修改my.cnf文件

vim /etc/my.cnf

[mysqld]
 basedir = /usr/local/mysql 
 datadir = /usr/local/mysql/data
 socket = /usr/local/mysql/mysql.sock
 character-set-server=utf8
 port = 3306
 sql_mode=no_engine_substitution,strict_trans_tables
 [client]
 socket = /usr/local/mysql/mysql.sock
 default-character-set=utf8

esc保存

:wq 退出

8建立mysql服务

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

cp mysql.server /etc/init.d/mysql
chmod +x /etc/init.d/mysql

添加到系统服务

chkconfig --add mysql

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

chmod +x /etc/rc.d/init.d/mysqld

chkconfig --add mysqld

检查服务是否生效

chkconfig --list mysqld

9. 配置全局环境变量

编辑 / etc/profile 文件

# vi /etc/profile

在 profile 文件底部添加如下两行配置，保存后退出

export path=$path:/usr/local/mysql/bin:/usr/local/mysql/lib

export path

设置环境变量立即生效

source /etc/profile

10.启动mysql服务

service mysql start

查看初始密码

cat /root/.mysql_secret

11.登录mysql

mysql -uroot -p密码

修改密码：

set password for 'root'@localhost=password('123456'); #对应的换成你自己的密码即可了。

12设置可以远程登录

mysql>use mysql

mysql>update user set host='%' where user='root' limit 1;

刷新权限

mysql>flush privileges;

然后检查3306端口是否开放

netstat -nupl|grep 3306

开放3306端口

firewall -cmd --permanent --add-prot=3306/tcp

重启防火墙

firewall -cmd --reload
