mysql5.7.36二进制部署

一、准备

1.1、包下载地址

https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.36-el7-x86_64.tar.gz

https://www.percona.com/downloads/Percona-XtraBackup-2.4/LATEST/

1.2、依赖检查

yum remove mariadb

1.3、时间同步

yum -y install ntp

ntpq -p

二、Mysql环境安装

2.1、创建系统用户

useradd --system mysql

2.2、创建目录并授权

mkdir -p /data/mysql/{binlogs,dbfiles,logs,relays}
chown -R mysql. /data/mysql

2.3、安装包下载及解压

wget https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.36-el7-x86_64.tar.gz && tar xf mysql-5.7.36-el7-x86_64.tar.gz -C /usr/local/

vim /etc/bashrc
...
​
# Mysql
export MYSQL_HOME=/usr/local/mysql-5.7.36
export PATH=$PATH:$MYSQL_HOME/bin
