#4.安装MySQL
#对于mysql来说我们一般安装下面四个文件就好
rpm -ivh percona-server-server-8.0.22-13.1.el7.x86_64.rpm percona-server-client-8.0.22-13.1.el7.x86_64.rpm percona-server-shared-8.0.22-13.1.el7.x86_64.rpm percona-server-shared-compat-8.0.22-13.1.el7.x86_64.rpm
 
#5.编写my.cnf文件
 
#6.创建必需的文件夹以及授权 根据配置文件中操作
mkdir -p /data/mysql/
mkdir -p /data/logs/
mkdir -p /data/mysql_tmp
chown -R mysql:mysql /data/mysql_tmp
chown -R mysql:mysql /data/mysql
chown -R mysql:mysql /data/logs
 
#7.修改/etc/systemd/system/mysql.service 以及修改文件中open_file_limits的值
mv /etc/systemd/system/mysql.service /etc/systemd/system/mysqld.service
 
# Sets open_files_limit
LimitNOFILE = 10000
#修改为65535
LimitNOFILE = 65535
 
#修改完之后重新reload
systemctl daemon-reload
 
#8. 启动mysqld服务
systemctl start mysqld
 
#9.加入开机自启
systemctl enable mysqld
 
#查看是否加入成功
systemctl list-unit-files |grep mysqld
 
#10.修改MySQL密码
cat /data/logs/mysql-error.log |grep temporary
#用临时密码登录到mysql修改密码
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '你的密码';
 
 
#12.将第五步中的配置文件取消注释，然后重新启动mysqld
 
#整理
如果遇到问题
yum install numactl
安装对应的依赖。
