Centos 7 下載安裝 mysql server 5.7
更改權限
[zoro@localhost ~]$ su root
輸入密碼進來 管理者命令行
切換目錄
[root@localhost zoro]# cd /root
下載安裝包MySQL5.7 Linux版本
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
打開目錄有這麼個包
[root@localhost ~]# ls
mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
安裝依賴
[root@localhost ~]# rpm -qa |grep libaio
[root@localhost ~]#
[root@localhost ~]# yum -y install libaio
// 安裝好後查看
[root@localhost ~]# rpm -qa |grep libaio
libaio-0.3.109-13.el7.x86_64
[root@localhost ~]# rpm -qa | grep numactl
[root@localhost ~]#
[root@localhost ~]# yum -y install numactl
// 安裝好後查看
[root@localhost ~]# rpm -qa | grep numactl
numactl-libs-2.0.9-7.el7.x86_64
準備工作完畢！！！
解壓準備好的安裝包
[root@localhost ~]# tar -zxvf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
名字更改爲mysql 並且修改位置
[root@localhost ~]# mv mysql-5.7.24-linux-glibc2.12-x86_64 /usr/local/mysql
[root@localhost ~]# cd /usr/local
創建mysql組，創建mysql用戶，修改權限
[root@localhost local]# groupadd mysql
[root@localhost local]# useradd -g mysql mysql
//修改文件用戶
[root@localhost local]# chown -R mysql mysql/
//修改文件用戶組
[root@localhost local]# chgrp -R mysql mysql/
[root@localhost local]# ll
mysql 文件夾下創建data 目錄
[root@localhost local]# mkdir /usr/local/mysql/data
編譯安裝並初始化mysql,務必記住初始化輸出日誌末尾的密碼（數據庫管理員臨時密碼）
cd /usr/local/mysql/bin
[root@localhost bin]# ./mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ --lc_messages_dir=/usr/local/mysql/share --lc_messages=en_US

修改配置文件
[root@localhost local]# vi /etc/my.cnf
複製下面的, 貼到 /etc/my.cnf 裏面
[mysql]

cd /usr/local/mysql
[root@localhost mysql]# cp ./support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql]#
複製啓動腳本到資源⽬錄
[root@localhost mysql]# vi /etc/init.d/mysqld
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
# Default value, in seconds, afterwhich the script should timeout waiting
# for server start.
# Value here is overriden by value in my.cnf.
# 0 means don't wait at all
# Negative numbers mean to wait indefinitely
service_startup_timeout=900
# Lock directory for RedHat / SuSE.
lockdir='/var/lock/subsys'
lock_file_path="$lockdir/mysql"
:wq
:wq 保存退出
設置爲可執行狀態
//授權爲可執行狀態
//⾸先增加 mysqld 服務控制腳本執⾏權限：
[root@localhost mysql]# chmod +x /etc/init.d/mysqld
//開機啓動
//同時將 mysqld 服務加⼊到系統服務：
[root@localhost mysql]# chkconfig --add mysqld
//最後檢查 mysqld 服務是否已經⽣效即可：
[root@localhost mysql]# chkconfig --list mysqld
啓動mysql
[root@localhost mysql]# service mysqld start

修改密碼
mysql> set password for root@localhost = password('123456');
Query OK, 0 rows affected, 1 warning (0.00 sec)
開放遠程連接
mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql>quit
==============================================================================================
但是還是有問題
windows 上的Navicat是連接不上的
這個問題該怎麼解決呢？
打開遠程訪問權限，修改完退出mysql ,quit 命令
BY 後面是數據庫密碼
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY '123456' WITH GRANT OPTION;
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql>quit
Bye
防火牆開放mysql使用的3306端口
[root@localhost mysql]# cd /root
[root@localhost ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
success
重啓防火牆
[root@localhost ~]# systemctl restart firewalld.service
[root@localhost ~]#
查看防火牆開放的端口
[root@localhost ~]# firewall-cmd --list-ports
3306/tcp
