1. 去官网下载安装包
下载链接:点击打开链接
https://dev.mysql.com/downloads/mysql/
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
1
|
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
1
|
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
1
|
mkdir data
|
4.创建 mysql 用户组和 mysql 用户

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
1

|
mkdir mysql_install_db
chmod 777 ./mysql_install_db
|
初始化
1
|
bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data //初始化数据库

/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 directory2018-04-29 17:06:30 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
