Centos7安裝完畢後重啟提示Initial setup of CentOS Linux 7 (core)的解決方案

問題：

CentOS7安裝完畢，重新開機啟動後顯示：

Initial setup of CentOS Linux 7 (core)

1) [x] Creat user 2) [!] License information

(no user will be created) (license not accepted)

Please make your choice from above [‘q‘ to quit | ‘c‘ to continue | ‘r‘ to refresh]:

解決方案：

輸入“1”，按Enter鍵

輸入“2”，按Enter鍵

輸入“q"，按Enter鍵

輸入“yes”，按Enter鍵

 

CentOS設定靜態IP地址

vi /etc/sysconfig/network-scripts/ifcfg-enp0s8

 

BOOTPROTO=static #dhcp改為static

IPADDR=172.31.44.100 #靜態IP

GATEWAY=172.31.44.1 #預設閘道

NETMASK=255.255.255.0 #子網路遮罩

DNS1=172.28.4.103 #DNS 配置

 

CentOS 7 修改主機名稱

hostname

hostnamectl set-hostname "Registry"

hostname

 

關防火牆

/etc/init.d/iptables stop

systemctl stop firewalld.service #停止firewall

systemctl disable firewalld.service #禁止firewall開機啟動

systemctl restart network #重啟網路 service network restart

 

開啟連接埠號碼

vim /etc/sysconfig/iptables

centos防火牆開啟連接埠--在22連接埠後添加一行

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

service iptables restart

 

Centos7設定成開機預設命令列模式

1，命令模式

systemctl set-default multi-user.target

2,圖形模式

systemctl set-default graphical.target

 

ssh [email protected]

 

如何開啟Centos7系統的SSH服務

1、登入Centos7系統。

樣本：使用root使用者登入。

註：若為非root使用者登入，輸入執行某些命許可權不夠時需加sudo

 

2、查看SSH是否安裝。

輸入命令：rpm -qa | grep ssh

註：若沒安裝SSH則可輸入：yum install openssh-server安裝。

 

3、啟動SSH服務。

輸入命令：service sshd restart  重啟SSH服務。

  命令：service sshd start 啟動服務 |  命令：service sshd stop 停止服務  

  重啟後可輸入：netstat -antp | grep sshd 查看是否啟動22連接埠（可略）。

 

4、如何設定SSH服務為開機啟動？

輸入命令：chkconfig sshd on 即可。

註：若是chkconfig sshd off則禁止SSH開機啟動。

 

5、遠端存取串連Centos7系統。

Windows下使用：putty、SecureCRT可遠端連線SSH服務。

Linux下直接使用命令：ssh ip（如：ssh 192.168.1.11）。

 

配置Java環境變數

vim /etc/profile

 

export JAVA_HOME=/root/Java/jdk1.7.0_79

export PATH=$JAVA_HOME/bin:$PATH

 

export MAVEN_HOME=/root/Java/apache-maven-3.3.9

export PATH=$MAVEN_HOME/bin:$PATH

 

source /etc/profile

 

cron

http://blog.csdn.net/yq495/article/details/7399277

1、yum install vixie-cron

2、vi backup.sh

#!/bin/sh

# file:/home/mysql/backup.sh

today=`date +%Y%m%d`

echo $today

mysqldump -uroot -pYunluqwe -h 127.0.0.1 yunlu > /home/mysql/backup/$today.sql

3、crontab -e

33 3 * * * /home/mysql/backup/backup.sh

4、/sbin/service crond restart

安裝mysql 

http://www.cnblogs.com/hb_cattle/archive/2011/10/16/2213825.html

卸載老版本

yum remove mysql-libs-5.1.71-1.el6.x86_64

rpm -qa | grep mysql

yum -y install perl

yum install libaio

rpm -ivh libaio-0.3.107-10.el6.x86_64.rpm

rpm -ivh MySQL-server-5.5.39-2.rhel5.x86_64.rpm

rpm -ivh MySQL-client-5.5.39-2.rhel5.x86_64.rpm

rpm -ivh MySQL-devel-5.5.39-2.rhel5.x86_64.rpm

 

修改 mysql 字元集

cp /usr/share/doc/mysql-server-5.1.61/my-medium.cnf /etc/my.cnf

vi /etc/my.cnf

[client]

default-character-set=utf8

 

[mysqld]

character-set-server=utf8

collation-server=utf8_general_ci

init-connect = ‘set names utf8‘

 

flush privileges;

 

Centos mysql 配置主從

 

Master

# The MySQL server

[mysqld]

user = mysql

pid-file = /var/lib/mysql/mysqld.pid

socket = /var/lib/mysql/mysqld.sock

port = 3306

basedir = /usr

datadir = /var/lib/mysql

tmpdir = /tmp

log-bin = master-bin

log-bin-index = master-bin.index

server-id = 1

 

CREATE USER repl_user;

GRANT REPLICATION SLAVE ON *.* TO repl_user IDENTIFIED BY ‘[email protected]#qwe‘;

 

Slave

# The MySQL server

[mysqld]

user = mysql

pid-file = /var/lib/mysql/mysqld.pid

socket = /var/lib/mysql/mysqld.sock

port = 3306

basedir = /usr

datadir = /var/lib/mysql

tmpdir = /tmp

server-id = 2

relay-log-index = slave-relay-bin.index

relay-log = slave-relay-bin

log-bin=mysql-bin

?

注釋掉下面的

#server-id = 1

 

CHANGE MASTER TO MASTER_HOST = ‘60.194.51.21‘, MASTER_PORT = 3306, MASTER_USER = ‘repl_user‘, MASTER_PASSWORD = ‘[email protected]#qwe‘;

 

START SLAVE;

 

停止主從複製

slave stop;

reset slave;

flush privileges;
