搭建yum源
分为两步，先搭建本地yum源，再搭建ftpyum源。
1.本地yum源
1：将iso文件复制到需要的目录下
2：mkdir /mnt/iso
3：mount */*.iso /mnt/iso
4：vi vi /etc/yum.repos.d/local.repo
内容如下：
[local]
name=local
baseurl=file:///mnt/iso
enabled=1
gpgcheck=0
然后执行命令，刷新yum源
yum clean all
yum search all
如果没有问题，则：安装vsftpd
yum install vim vsftpd -y
systemctl enable vsftpd
systemctl restart vsftpd
systemctl status vsftpd
安装后，默认ftp路径是/var/ftp/pub/
cp -r /mnt/iso/* /var/ftp/pub
关闭防火墙和沙盒机制
systemctl disable firewalld
vim /etc/selinux/config
改为disabled
需要重启生效
reboot
暂时session的：setenforce 0
getenforce
配之ftpyum源
mv local.repo ftp.repo
修改baseurl=ftp://$IP/pub
yum clean all
yum search all
安装相关包，修改时区
yum install gcc gdb iotop libaio net-snmp perf sysstat ntp ntpdate vim -y
java rpm包
rpm -ivh *.rpm
systemctl enable snmpd
systemctl restartt snmpd
timedatectl set-timezone Asia/Shanghai
还有ntp配置
NTP 配置
修改默认参数
vim /etc/sysctl.conf
net.core.rmem_default = 2097152
net.core.wmem_default = 2097152
net.core.rmem_max = 8388608
net.core.wmem_max = 8388608
system -p
vim /etc/profile
ulimit -s 20480
修改网卡配置，不赘述
设置磁盘准备，自动挂载
mkfs.ext4 /dev/sdb
mkdir /mnt/sdb
mount /dev/sdb /mnt/sdb
blkid
vim /etc/fstab
UUID=09dd5e41-4577-4438-8467-620b8c8e39c2 /mnt/sdb ext4 defaults 0 0
准备完毕
准备启动数据库
