Linux安装Mysql_8.0.18_linux rpm安装mysql8.0.18 报upacking of archive failed

 

1.下载MySQL，http://dev.mysql.com/downloads/mysql/

 

选择适合你的版本下载即可。

2.将下载MySQL包上传到linux，进行解压：tar -xvf mysql.....

3.移动并修改文件名: mv /bigdata/mysql-8.0.18-linux-glibc2.12-x86_64.tar /usr/local/mysql

4.新建mysql用户、组及目录：groupadd mysql；useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql

5.创建数据仓库目录：mkdir /data/mysql；

6.改变目录属有者：chown -R mysql .；chgrp -R mysql .；chown -R mysql /data/mysql；【注：分号前的' .'】

7.初始化：① bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql 【注意你的参数值】

 此处需要注意记录生成的临时密码，如上文结尾处的： o9dQXD_R,g&w

② bin/mysql_ssl_rsa_setup  --datadir=/data/mysql

8.修改系统配置文件：

① cp mysql.server /etc/init.d/mysql   【mysql.server 在你mysql_home的support-files目录中】

vim /etc/init.d/mysql

basedir=/usr/local/mysql
datadir=/data/mysql

② vi /etc/my.cnf

[mysqld]
datadir=/usr/local/mysql/
datadir=/data/mysql/
socket=/data/mysql/mysql.sock
# 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
 
log-error=/usr/local/mysql/mysqld.log
 
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
 
 
character_set_server=utf8
init_connect='SET NAMES utf8'
 
 
#
# include all files from the config directory
#
!includedir /etc/my.cnf.d

9.启动： /etc/init.d/mysql start

/etc/init.d/mysql start

10.登陆：

mysql -hlocalhost -uroot -p

输入：第七步时候生成的临时密码 o9dQXD_R,g&w

输入完后无问题直接进入，而我在此报错。。。

①错误1

解决方式：ln -s /data/mysql/mysql.sock /tmp/mysql.sock 【注：/data/mysql/mysql.sock文件地址根据实际情况填写】

②  错误2
Starting MySQL.The server quit without updating PID file (/data/mysql//vm10-38-248-204.ksc.com.pid).                                      [失败]

解决方式：配置 vi /etc/my.cnf

11.登陆到mysql第一件事就是修改临时密码，不然你操作任何命令，都是报错：

修改密码：alter user 'root'@'localhost' identified by '123456';

12.添加系统路径
# vim /etc/profile
添加：
export PATH=/usr/local/mysql/bin:$PATH

source /etc/profile

13.设置系统命令，不然无法使用service mysqld status

①find / -name mysql.server

②cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

14.mysql服务设置远程连接 解决1251 client does not support ..问题

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'newpassword';

附加：

Linux杀掉MySQL进程（关键词：Linux/MySQL/杀死进程/mysql/mysqld）
1.查看mysql程序对应的进程号使用命令：ps -e|grep mysql
2.杀死mysql进程使用命令：sudo kill -9 mysql的进程号
3.杀死mysqld进程使用命令：sudo killall mysqld
4.检查是否还有mysql进程存在使用命令：psps -e|grep mysql
