Linux centos 推拉、共享、监控的设置的分享

新建四台虚拟机

打开第一台连接shell更改主机名、网卡

backup

1、主机名网卡配置

    [root@jytcentos7.6 ~]# hostnamectl set-hostname backup #更改主机名
    [root@jytcentos7.6 ~]# sed -i 's#200#41#'g /etc/sysconfig/network-scripts/ifcfg-eth0 #更改网卡ip
    [root@jytcentos7.6 ~]# sed -i 's#200#41#'g /etc/sysconfig/network-scripts/ifcfg-eth1 #更改网卡ip
    [root@jytcentos7.6 ~]# systemctl restart network    #重启网卡

连接xshell

    [root@backup ~]#
    ip add #查看
    2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu     1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:ae:8e:87 brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.41/24 brd 10.0.0.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::20c:29ff:feae:8e87/64 scope link
       valid_lft forever preferred_lft forever
    3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:ae:8e:91 brd ff:ff:ff:ff:ff:ff
    inet 172.16.1.41/24 brd 172.16.1.255 scope global eth1
       valid_lft forever preferred_lft forever
    inet6 fe80::20c:29ff:feae:8e91/64 scope link
       valid_lft forever preferred_lft forever
- 更改第二台、第三台、第四台

1nfs

    [root@jytcentos7.6 ~]# hostnamectl set-hostname nfs
    [root@jytcentos7.6 ~]# sed -i 's#200#31#'g /etc/sysconfig/network-scripts/ifcfg-eth0
    [root@jytcentos7.6 ~]# sed -i 's#200#31#'g /etc/sysconfig/network-scripts/ifcfg-eth1
    [root@jytcentos7.6 ~]# systemctl restart network
    [root@nfs ~]#

2web01

    [root@jytcentos7.6 ~]# hostnamectl set-hostname     web01
    [root@jytcentos7.6 ~]# sed     -i 's#200#7#'g /etc/sysconfig/network-scripts/ifcfg-eth0
    [root@jytcentos7.6 ~]# sed -i 's#200#7#'g /etc/sysconfig/network-scripts/ifcfg-eth1
    [root@jytcentos7.6 ~]# systemctl restart network
    [root@web01 ~]#

3web02

    [root@jytcentos7.6 ~]# hostnamectl set-hostname web02
    [root@jytcentos7.6 ~]# sed -i 's#200#8#'g /etc/sysconfig/network-scripts/ifcfg-eth0
    [root@jytcentos7.6 ~]# sed -i 's#200#8#'g /etc/sysconfig/network-scripts/ifcfg-eth1
    [root@jytcentos7.6 ~]# systemctl restart network
    [root@web02 ~]#

2backup 配置rsyncd.conf

    useradd rsync
    mkdir /backup
    chown -R rsync.rsync /backup
    cp /etc/rsyncd.conf{,.ori}    #做备份防止出错
cat >/etc/rsyncd.conf<<EOF
　#rsync_config_______________start
   #created by oldboy
   #site: http://www.oldboyedu.com
   uid = rsync    #管理备份目录的用户
   gid = rsync    # 管理备份目录的用户组
   use chroot = no    # 安全功能，数据是否锁定到备份目录
   max connections = 200 #并发链接同时多少用户端访问
   timeout = 600 #超时时间
   pid file = /var/run/rsyncd.pid   #进程号所在文件
   lock file = /var/run/rsync.lock #锁文件
   log file = /var/log/rsyncd.log   #日志文件查看报错等
   ignore errors   # 忽略错误
   read only = false   #可写
   list = false    #不容许列表
   hosts allow = 172.16.1.0/24   #那些主机可以访问
   hosts deny = 0.0.0.0/32        #那些主机不容许访问
   auth users = rsync_backup #远程虚拟连接用户
   secrets file = /etc/rsync.password   #存放密码的文件：格式：用户名：密码权限必须660
   [backup]    #【模块名】远程访问使用模块名访问
   comment = welcome to oldboyedu backup!   #说明注释
   path = /backup/ #服务器端用户备份的目录用户合组，rsync.rsync
   EOF
    systemctl start rsyncd #开启rsync服务
    systemctl enable rsyncd #设置开机自启
    systemctl status rsyncd #查看服务状态
    echo "rsync_backup:oldboy" > /etc/rsync.password #添加密码
    chmod 600 /etc/rsync.password #设置密码权限
    cat /etc/rsync.password
    ls -l /etc/rsync.password
- 欧了！

nfs推拉配置

    [root@nfs ~]#     echo ' export     RSYNC_PASSWORD=oldboy' >>/etc/bashrc
    [root@nfs ~]#     tail -1 /etc/bashrc
     export RSYNC_PASSWORD=oldboy
    [root@nfs ~]#      . /etc/bashrc
    [root@nfs ~]#     echo $RSYNC_PASSWORD
    oldboy
    [root@nfs ~]#

共享web01和web02以nfs为媒介

1、nfs配置

    yum install nfs-utils rpcbind -y    #下载插件
    rpm -qa nfs-utils rpcbind #查看插件
    systemctl start nfs #开启服务
    systemctl enable nfs #设置开机自启
    mkdir /data
    echo "#oldboy-jyt" >/etc/exports
    echo "/data 172.16.1.0/24(rw,sync)" >>/etc/exports #设置共享目录
    grep nfsno /etc/passwd
    chown -R nfsnobody.nfsnobody /data #设置目录属主属组
    systemctl reload nfs #开启nfs服务
    showmount -e 172.16.1.31 #查看共享目录
        Export list for 172.16.1.31:
        /data 172.16.1.0/24
配置成功

2、web01

3、web02

    yum install nfs-utils rpcbind -y#下载插件
    rpm -qa nfs-utils rpcbind
    showmount -e 172.16.1.31
    mount -t nfs 172.16.1.31:/data /mnt#挂载共享目录
    chmod +x /etc/rc.local
    echo "/usr/bin/mount -t nfs 172.16.1.31:/data /mnt" >>/etc/rc.local #设置开机自动挂载

监控nfs的data目录做到实时推送备份

安装插件

yum install inotify-tools -y
rpm -ql inotify-tools|head -2
