1、安装相关包
yum -y install libaio numactl-libs
2、创建用户和组
groupadd mysql
useradd -r -g mysql -s /bin/false mysql
3、准备二进制压缩包
tar xf mysql-5.7.38-linux-glibc2.12-x86_64.tar.gz) –C /usr/local
cd /usr/local/
ln -s mysql-5.7.38-linux-glibc2.12-x86_64 mysql
chown -R mysql.mysql /usr/local/mysql/
4、准备PATH变量
echo ‘PATH=/usr/local/mysql/bin:$PATH’ > /etc/profile.d/mysql.sh
. /etc/profile.d/mysql.sh
5、准备配置文件
cp /etc/my.cnf{,.bak}
vim /etc/my.cnf
[mysqld]
datadir=/data/mysql
skip_name_resolve=1
socket=/data/mysql/mysql.sock
log-error=/data/mysql/mysql.log
pid-file=/data/mysql/mysql.pid
[client]
socket=/data/mysql/mysql.sock
6、生成数据库文件,并提取root密码
mysqld –initialize –user=mysql –datadir=/data/mysql
…省略…
2022-06-30T13:03:54.258140Z 1 [Note] A temporary password is generated for
root@localhost: LufavlMka6,! #注意生成root的初始密码
grep password /data/mysql/mysql.log
2022-06-30T13:31:30.458826Z 1 [Note] A temporary password is generated for
root@localhost: LufavlMka6,!
awk ‘/temporary password/{print $NF}’ /data/mysql/mysql.log
LufavlMka6,！
7、准备服务脚本和启动
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chkconfig –add mysqld
service mysqld start
8、修改密码
mysqladmin -uroot -p’LufavlMka6,!’ password 123456
