centos7 安装包安装mysql8.0.18 rpm-bundle

一、资源地址

下载地址  https://dev.mysql.com/downloads/mysql/

二、安装前准备，卸载自带的 mariadb，安装依赖环境

列出已安装的 mariadb

[root@mysql ~]# rpm -qa | grep mariadb mariadb-libs-5.5.60-1.el7_5.x86_64 方法一：rpm -e --nodeps 卸载 mariadb [root@mysql ~]# rpm -e --nodeps mariadb-libs-5.5.60-1.el7_5.x86_64 方法二：yum -y remove 卸载 mariadb [root@mysql ~]# yum -y remove mariadb-libs-5.5.60-1.el7_5.x86_64

 

如果有多余的残留目录删除它，没有则跳过

[root@mysql ~]# find / -name mysql -print 如下： [root@mysql ~]# rm -rf /var/lib/mysql [root@mysql ~]# rm -rf /var/lib/mysql/mysql [root@mysql ~]# rm -rf /usr/bin/mysql [root@mysql ~]# rm -rf /usr/lib64/mysql

 

安装基础软件。

[root@mysql ~]# yum -y install wget (如果你不用ftp或者lrzsz上传) [root@mysql ~]# yum -y install lrzsz (简单好用的上传下载软件) [root@mysql ~]# yum -y install vim

 

安装依赖软件。

[root@mysql ~]# yum -y install net-tools [root@mysql ~]# yum -y install openssl openssl-devel [root@mysql ~]# yum -y install libaio libaio-devel [root@mysql ~]# yum -y install perl perl-devel [root@mysql ~]# yum -y install perl-JSON.noarch [root@mysql ~]# yum -y install autoconf

 

三、查看、关闭 firewall 防火墙

[root@mysql home]# firewall-cmd --state [root@mysql home]# systemctl stop firewalld.service [root@mysql home]# systemctl disable firewalld.service

 

四、关闭selinux，进入到/etc/selinux/config文件，将SELINUX=enforcing 改为SELINUX=disabled

[root@mysql home]# vi /etc/selinux/config

 

五、重启 CentOS…

[root@mysql home]# reboot

 

六、上传mysql的tar包，解压tar包

[root@mysql ~]# cd /home [root@mysql home]# tar -xvf mysql-8.0.17-1.el7.x86_64.rpm-bundle.tar [root@mysql mysql]# ls -lShr

 

 

七、开始安装mysql

PS：注意安装顺序 common -> -client-plugins -> libs -> client -> server [root@mysql mysql]# rpm -ivh mysql-community-common-8.0.17-1.el7.x86_64.rpm [root@mysql mysql]# rpm -ivh mysql-community-libs-8.0.17-1.el7.x86_64.rpm [root@mysql mysql]# rpm -ivh mysql-community-client-8.0.17-1.el7.x86_64.rpm [root@mysql mysql]# rpm -ivh mysql-community-server-8.0.17-1.el7.x86_64.rpm [root@mysql mysql]# rpm -ivh mysql-community-libs-compat-8.0.17-1.el7.x86_64.rpm（可选） [root@mysql mysql]# rpm -ivh mysql-community-devel-8.0.17-1.el7.x86_64.rpm（可选） [root@mysql mysql]# rpm -ivh mysql-community-embedded-compat-8.0.17-1.el7.x86_64.rpm（可选） [root@mysql mysql]# rpm -ivh mysql-community-test-8.0.17-1.el7.x86_64.rpm（可选） [root@mysql mysql]# rpm -qa | grep mysql

 

八、初始化数据库，目录授权，启动mysql服务 [注意操作顺序]

 

 [root@gnome mysql]# mysqld --initialize --console --lower_case_table_names=1 （初始化，并设置不区分大小写） [root@gnome mysql]# chown -R mysql:mysql /var/lib/mysql/ [root@gnome mysql]# systemctl start mysqld

 

九、查看是否启动成功，active (running)

 

 

 

十、查看初始化后的临时密码

[root@gnome mysql]# grep 'temporary password' /var/log/mysqld.log 或者 [root@gnome mysql]# cat /var/log/mysqld.log | grep 'temporary password'

十一、登录mysql

[root@mysql home]# mysql -u root -p Enter password: 直接粘贴初始密码 ，回车确认

 

 

十二、修改初始密码，授权远程登录

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'HomeTest$2019'; (修改 “HomeTest$2019” 为你自己的密码) mysql> use mysql; (切换到mysql库) mysql> update user set host = "%" where user='root'; (授权远程登录) mysql> flush privileges; (刷新) mysql> quit; (退出登录)

 

十四、配置 后重启

vim /etc/my.cnf
