centos7 二进制安装mysql 5.7.33

官方文档：

https://dev.mysql.com/doc/refman/5.7/en/binary-installation.html

下载地址：

https://dev.mysql.com/downloads/mysql/5.7.html

版本选择linux通用二进制x64：

# Select Operating System:
linux-Generic

# Select OS Version:
linux-Generic-(glibc2.12), (x86, 64-bit)

下载二进制包

wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.32-linux-glibc2.12-x86_64.tar.gz -P /tmp

卸载默认mariadb

rpm -qa | grep mariadb | xargs yum remove -y

安装mysql依赖

yum install -y libaio numactl-devel

创建mysql用户和用户组

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

解压二进制包到/opt/mysql目录

mkdir -p /opt/mysql
tar -zxvf /tmp/mysql-5.7.33-linux-glibc2.12-x86_64.tar.gz -C /opt/mysql --strip=1

配置环境变量，将/opt/mysql/bin目录添加到path变量中

echo 'export PATH=$PATH:/opt/mysql/bin' > /etc/profile.d/mysql.sh
source /etc/profile.d/mysql.sh
mysql --version

创建数据存储路径并授权

mkdir -p /opt/mysql/{data,logs,etc}
mkdir -p /opt/mysql/logs/binlog

创建mysql配置文

cat > /opt/mysql/etc/my.cnf <<EOF

socket=/tmp/mysql.sock

[mysqld]
port = 3306

配置目录权限

chown -R mysql.mysql /opt/mysql

初始化mysql

mysqld --defaults-file=/opt/mysql/etc/my.cnf --initialize

创建systemd启动文件

cat > /etc/systemd/system/mysqld.service << 'EOF'

启动mysql服务

systemctl enable --now mysqld

查看mysql服务运行状态

在日志文件里会提示一个临时密码，记录这个密码

password=$(grep 'temporary password' /opt/mysql/logs/error.log | awk '{print $NF}')

登录和重置root密码

mysql -uroot -p$password

ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
flush privileges;

配置支持远程连接

use mysql;
update user set host = '%' where user = 'root';
flush privileges;

重新登录进行验证

mysql -uroot -p123456

mysql -uroot -p123456 -h 192.168.92.20
