Linux下安裝mysql-5.7.30詳細步驟

前言
下面記錄了我在Linux環境下安裝Mysql的完整過程，實操記錄，只為讓更多人少踩坑，本次安裝版本為：mysql-5.7.30，64位操作系統
官網下載地址：mysql-5.7.30-el7-x86_64.tar.gz
百度網盤地址：百度網盤地址 提取碼：lyqh

1、安裝前准備
檢測系統是否自帶mysql

[root@localhost /]# rpm -qa | grep mysql

如果是，則使用下面命令進行刪除：

[root@localhost /]# rpm -e --nodeps ‘上一步查找的名稱’

刪除成功后，查詢所有Mysql對應的文件夾

[root@localhost ~]# whereis mysql
mysql: /usr/bin/mysql /usr/local/mysql
[root@localhost ~]# find / -name mysql
/run/lock/subsys/mysql
/etc/rc.d/init.d/mysql
/usr/bin/mysql
/usr/local/mysql
/usr/local/mysql/bin/mysql
/usr/local/mysql/include/mysql
/usr/local/mysql/data/mysql

刪除上面查找的所有文件夾
2、安裝
使用rz命令上傳下載好的jar包

[root@localhost ~]# cd /usr/local/
[root@localhost local]# rz

解壓

[root@localhost local]# tar -zxvf mysql-5.7.30-el7-x86_64.tar.gz

修改解壓目錄名稱

[root@localhost local]# mv mysql-5.7.30-el7-x86_64/ mysql

在/usr/local/mysql目錄下創建data目錄

[root@localhost local]# mkdir mysql/data

檢查mysql用戶組和用戶是否存在，如果沒有，則創建

[root@localhost local]# cat /etc/group | grep mysql
[root@localhost local]# cat /etc/passwd | grep mysql
[root@localhost local]# groupadd mysql
[root@localhost local]# useradd -r -g mysql mysql

更改mysql目錄下所屬的用戶組和用戶，以及權限

[root@localhost local]# chown -R mysql:mysql /usr/local/mysql/
[root@localhost local]# chmod -R 755 /usr/local/mysql

編譯安裝並初始化mysql

[root@localhost local]# cd mysql/bin/
[root@localhost bin]# ./mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data/ --basedir=/usr/local/mysql/

8. 查看並安裝libaio包

[root@localhost bin]# rmp -qa|grep libaio
-bash: rmp: command not found
[root@localhost bin]# yum -y install libaio-devel.x86_64

9.再次執行步驟7，並記住日志最后的初始化密碼（記住）

10.編輯配置文件my.cnf

[root@localhost bin]# vi /etc/my.cnf

添加配置如下

[mysqld]
datadir=/usr/local/mysql/data
port=3306
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd
[mysqld_safe]
log-error=/usr/local/mysql/data/mysql.log
pid-file=/usr/local/mysql/data/mysql.pid

11.啟動mysql服務器

[root@localhost bin]# /usr/local/mysql/support-files/mysql.server start

13. 添加軟連接，並重啟mysql服務

[root@localhost bin]# ln -s /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
[root@localhost bin]# ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql
[root@localhost bin]# service mysql restart
Shutting down MySQL.. SUCCESS!
Starting MySQL. SUCCESS!

14.登錄mysql，修改密碼為123456(登錄的密碼是步驟9中初始化密碼)

[root@localhost bin]# mysql -u root -p
Enter password:
mysql>set password for root@localhost = password('123456');

15.開放遠程連接

mysql>use mysql;
msyql>update user set user.Host='%' where user.User='root';
mysql>flush privileges;

3、測試
1.關閉Linux防火牆

[root@localhost bin]# systemctl stop firewalld.service

2.Navicat連接測試
