檢查環境

• 是否安裝mysql

rpm -qa|grep -i mysql

• 是否安裝MariaDB

rpm -qa|grep -i mariadb

• 解除安裝命令

yum -y remove xxx

• 準備安裝包
  mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz
• 是否安裝libaio

rpm -qa|grep libaio

• 安裝libaio

yum install libaio-devel.x86_64
 

解壓安裝包並重命名

tar -zxvf mysql-5.7.29-linux-glibc2.12-x86_64.tar.gz
mv mysql-5.7.29-linux-glibc2.12-x86_64 mysql-5.7.29

建立使用者和使用者組

groupadd mysql
useradd -r -g mysql -s /bin/false mysql

授予目錄許可權

chown -R mysql.mysql /usr/software/mysql

建立data資料夾

mkdir data

初始化資料庫

/usr/software/mysql/mysql-5.7.29/bin/mysqld --user=mysql --basedir=/usr/software/mysql/mysql-5.7.29 --datadir=/usr/software/mysql/mysql-5.7.29/data --initialize
 

• 記下臨時密碼 在完成後最後一行

配置檔案

vim /etc/my.cnf

[mysqld]
datadir=/usr/software/mysql/mysql-5.7.29/data
basedir=/usr/software/mysql/mysql-5.7.29
socket=/tmp/mysql.sock
user=mysql
port=3306
character-set-server=utf8

#跳過密碼驗證，忘記密碼 可以設定，然後修改密碼，再關閉
#skip-grant-tables

# 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=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
# include all files from the config directory
!includedir /etc/my.cnf.d
 

將mysql加入服務

cp /usr/software/mysql/mysql-5.7.29/support-files/mysql.server /etc/init.d/mysql

修改目錄basedir datadir

vim /etc/init.d/mysql

basedir=/usr/software/mysql/mysql-5.7.29
datadir=/usr/software/mysql/mysql-5.7.29/data

//開機啟動
chkconfig mysql on
//建立目錄
mkdir /etc/my.cnf.d/

啟動服務

service mysql start

配置環境變數

vim /etc/profile

export PATH=$PATH:/usr/software/mysql/mysql-5.7.29/bin

//使配置生效
source /etc/profile

登入mysql修改密碼、設定遠端

mysql -uroot -p

alter user 'root'@'localhost' identified by '201619706';
flush privileges;

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

//重啟服務
service mysql restart
