mkdir /usr/local/mysql/etc
touch /usr/local/mysql/etc/my.cnf
ln -s /usr/local/mysql/etc/my.cnf /usr/local/etc

修改权限

chown -R mysql:mysql /usr/local/mysql/*
chown -R mysql:mysql /data/db/mysql /data/log/mysql

生成初始化密码

cd /usr/local/mysql
bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/db/mysql
bin/mysql_ssl_rsa_setup
vim /data/log/mysql/error.log
查看初始化密码
grep 'temporary password' /data/log/mysql/error.log

将mysql的启动服务添加到系统服务中

cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system
mkdir -p /var/run/mysqld/
chown mysql:mysql /var/run/mysqld
systemctl start mysqld
service mysql start

启动mysql

service mysqld start
检查mysql启动是否正常
service mysqld status 或者 ps -ef | grep mysql
设置mysqld服务开机自启动
systemctl enable mysqld.service
检查mysqld开机自启动是否设置成功
systemctl list-dependencies | grep mysqld
