使用二进制包安装MySQL

安装依赖包

yum install libaio -y

下载安装包

wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.30-linux-glibc2.12-x86_64.tar.gz

解压创建目录

tar zxf mysql-5.7.30-linux-glibc2.12-x86_64.tar.gz -C /opt
ln -s /opt/mysql-5.7.30-linux-glibc2.12-x86_64 /opt/mysql
mkdir -p /data/mysql

修改启动脚本并添加开机自启动

sed -i '46s#basedir=#basedir=/opt/mysql#' /opt/mysql/support-files/mysql.server
sed -i '47s#datadir=#datadir=/data/mysql#' /opt/mysql/support-files/mysql.server
cp /opt/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld
chkconfig mysqld

创建用户

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

赋予data目录和base目录普通用户组

chown -R mysql.mysql /opt/mysql/
chown -R mysql.mysql /data/

ln -s /opt/mysql/bin/mysql /usr/bin/

创建配置文件

vim /etc/my.cnf

chown -R mysql.mysql /etc/my.cnf

初始化

/opt/mysql/bin/mysqld --initialize --user=mysql --basedir=/opt/mysql --datadir=/data/mysql

过滤初始密码

mysql_passwd=$(grep 'A temporary password is generated' /data/mysql/mysql.err |awk '{print $NF}')

启动服务

service mysqld start

修改初始密码

/opt/mysql/bin/mysqladmin -uroot -p${mysql_passwd} password '123456'

客户端环境变量

echo "export PATH=\$PATH:/opt/mysql/bin" | tee /etc/profile.d/mysql.sh
source /etc/profile.d/mysql.sh
