1. 去官網(wǎng)下載安裝包

下載鏈接：點(diǎn)擊打開鏈接

https://dev.mysql.com/downloads/mysql/

如果你的系統(tǒng)是32位選擇第一個(gè)，64位選擇第二個(gè)

也可以用wget 下載

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

解壓文件

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

2 移動(dòng)壓縮包到usr/local目錄下,并重命名文件

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

3.在MySQL根目錄下新建一個(gè)文件夾data,用于存放數(shù)據(jù)

mkdir data

4.創(chuàng)建 mysql 用戶組和 mysql 用戶

groupadd mysql
useradd -g mysql mysql

5.改變 mysql 目錄權(quán)限

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

注意最后有一點(diǎn)

6.初始化數(shù)據(jù)庫(kù)

創(chuàng)建mysql_install_db安裝文件

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 //初始化數(shù)據(jù)庫(kù)

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=Tlsi0O!
/usr/local/mysql/bin/mysqld (mysqld 8.0.11) initializing of server has completed

記錄好自己的臨時(shí)密碼：

twi=Tlsi0O!

這里遇到了問(wèn)題沒有l(wèi)ibnuma.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.

需要安裝 libnuma

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

安裝文件

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服務(wù)

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

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

添加到系統(tǒng)服務(wù)

chkconfig --add mysql

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

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

chkconfig --add mysqld

檢查服務(wù)是否生效

chkconfig --list mysqld

9. 配置全局環(huán)境變量

編輯 / etc/profile 文件

# vi /etc/profile

在 profile 文件底部添加如下兩行配置，保存后退出

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

export PATH

設(shè)置環(huán)境變量立即生效

source /etc/profile

10.啟動(dòng)MySQL服務(wù)

service mysql start

查看初始密碼

cat /root/.mysql_secret

11.登錄MySQL

mysql -uroot -p密碼

修改密碼：

SET PASSWORD FOR 'root'@localhost=PASSWORD('123456'); #對(duì)應(yīng)的換成你自己的密碼即可了。

12設(shè)置可以遠(yuǎn)程登錄

mysql>use mysql

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

刷新權(quán)限

mysql>flush privileges;

然后檢查3306端口是否開放

netstat -nupl|grep 3306

開放3306端口

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

重啟防火墻

firewall -cmd --reload
