2.4 安装系统以及系统设置
2.4.1 安装Redhat7.2
- 选择最小化安装
- 磁盘分区
| 分区 | 磁盘大小 |
|---|---|
| boot | 500m |
| / | 100g+ |
| /home | 50g+ |
| /var | 50g+ |
| /dfs | 100g+ |
2.4.2 修改主机名
分别修改每一台主机的主机名，方法如下
hostname 主机名称 #临时修改
hostnamectl set-hostname 主机名称 #永久修改
# vi /etc/hostname 在里面写入主机名 #编辑配置也可更改为永久
localhost.localdomain
# vi /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain
==修改后需要重新连接shell主机名才能生效==
2.4.3 配置IP地址
vi /etc/sysconfig/network-scripts/ifcfg-eth*****
添加如下信息
TYPE=Ethernet
BOOTPROTO=static #修改为静态
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=no
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=eth0
UUID=11a27cf6-7589-4220-8f93-8471d3c789fc
DEVICE=eth0
ONBOOT=yes #开机启动
IPADDR=192.168.1.243
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS=180.76.76.76
2.4.4 配置hosts
编辑 /etc/hosts文件 添加如下内容
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.240 jp-hadoop-00
192.168.1.241 jp-hadoop-01
192.168.1.242 jp-hadoop-02
192.168.1.243 jp-hadoop-03
192.168.1.244 jp-hadoop-04
192.168.1.245 jp-hadoop-05
192.168.1.246 jp-hadoop-06
192.168.1.247 jp-hadoop-07
192.168.1.248 jp-hadoop-08
192.168.1.249 jp-hadoop-09
192.168.1.55 jp-mysql-01
2.4.5 配置ssh免密登陆
-
配置 ssh
vi /etc/ssh/sshd_config， 找到以下内容，去掉前面的注释’#’ RSAAuthentication yes #启用 RSA 认证 PubkeyAuthentication yes #启用公钥私钥配对认证方式 AuthorizedKeysFile .ssh/authorized_keys #公钥文件路径 -
重启sshd服务
service sshd restart -
在每一台主机生成ssh 公钥和私钥,执行命令，加三个回车
ssh-keygen -t rsa -
分别将每一台机器的公钥文件值放到jp-hadoop-00:/root/.ssh/authorized_keys 文件中
scp .ssh/id_rsa.pub root@192.168.1.240:/root/id_rsa.pub cat id_rsa.pub >> /root/.ssh/authorized_keys
2.4.6 每一台主机分别执行脚本配置参数
-
执行脚本
#关闭防火墙 sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config systemctl stop firewalld systemctl disable firewalld #调整内核参数 echo 1 > /proc/sys/vm/overcommit_memory #调整ulimit和nproc sed -i '49d' /etc/security/limits.conf sed -i '/4/aroot - nofile 327680' /etc/security/limits.conf rm -rf /etc/pam.d/common-session echo 'session required pam_limits.so' > /etc/pam.d/common-session #调整内存交换 echo 'vm.swappiness=0' >> /etc/sysctl.conf #调整基础环境 echo never > /sys/kernel/mm/transparent_hugepage/defrag echo never > /sys/kernel/mm/transparent_hugepage/enabled echo 'echo never > /sys/kernel/mm/transparent_hugepage/defrag' >> /etc/rc.local echo 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' >> /etc/rc.local -
centos 7 禁用ipv6
1. 通过命令： Check to see if you’re installation is currently set up for IPv6: # cat /proc/sys/net/ipv6/conf/all/disable_ipv6 If the output is 0, IPv6 is enabled. If the output is 1, IPv6 is already disabled. 2. 临时禁用ipv6 vi /etc/sysctl.conf 添加下面的行： net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 执行命令 #sysctl -p 3. 永久禁用 # vim /etc/default/grub 在第6行 加上 GRUB_CMDLINE_LINUX="ipv6.disable=1" # grub2-mkconfig -o /boot/grub2/grub.cfg # reboot
