CentOS设置静态IP地址
vi /etc/sysconfig/network-scripts/ifcfg-enp0s8
BOOTPROTO=static #dhcp改为static
IPADDR=172.31.44.100 #静态IP
GATEWAY=172.31.44.1 #默认网关
NETMASK=255.255.255.0 #子网掩码
DNS1=172.28.4.103 #DNS 配置
CentOS 7 修改主机名
hostname
hostnamectl set-hostname "Registry"
hostname
关防火墙
/etc/init.d/iptables stop
systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动
systemctl restart network #重启网络 service network restart
打开端口号
vim /etc/sysconfig/iptables
centos防火墙开启端口--在22端口后添加一行
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
service iptables restart
Centos7设置成开机默认命令行模式
1，命令模式
systemctl set-default multi-user.target
2,图形模式
systemctl set-default graphical.target
ssh root@172.31.46.32
如何开启Centos7系统的SSH服务
1、登录Centos7系统。
示例：使用root用户登录。
注：若为非root用户登录，输入执行某些命权限不够时需加sudo
2、查看SSH是否安装。
输入命令：rpm -qa | grep ssh
注：若没安装SSH则可输入：yum install openssh-server安装。
3、启动SSH服务。
输入命令：service sshd restart 重启SSH服务。
命令：service sshd start 启动服务 | 命令：service sshd stop 停止服务
重启后可输入：netstat -antp | grep sshd 查看是否启动22端口（可略）。
4、如何设置SSH服务为开机启动？
输入命令：chkconfig sshd on 即可。
注：若是chkconfig sshd off则禁止SSH开机启动。
5、远程访问连接Centos7系统。
Windows下使用：putty、SecureCRT可远程连接SSH服务。
Linux下直接使用命令：ssh ip（如：ssh 192.168.1.11）。
配置Java环境变量
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

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

安装mysql
http://www.cnblogs.com/hb_cattle/archive/2011/10/16/2213825.html
卸载老版本
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 字符集
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 配置主从
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 ‘YUNLU!@#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
?
注释掉下面的
#server-id = 1
CHANGE MASTER TO MASTER_HOST = ‘60.194.51.21‘, MASTER_PORT = 3306, MASTER_USER = ‘repl_user‘, MASTER_PASSWORD = ‘YUNLU!@#qwe‘;
START SLAVE;
停止主从复制
slave stop;
reset slave;
flush privileges;
