  • Linux 网络一般设置

    一、更改IP及添加路由

    1、IPADDR=192.168.150.154    

    2、NETMASK=255.255.255.0

    3、GATEWAY=192.168.150.1

    Vi /etc/sysconfig/network-scripts/route-eno16777984

    10.50.1.0/24 via 10.5.16.221 dev eno16777984

    10.10.16.0/24 via 10.5.16.221 dev eno16777984

    Service network restart   // systemctl restart network

    二、关闭防火墙

             Systemctl stop firewalld.service

             Systemctl disable firewalld.service

             Firewall-cmd –state  (查看防火墙状态)   service firewalld status

             Centos6.9版本:service iptables stop(关闭)

                                           Service iptables start(开启)

                                           Service iptables status(查看)

                                           Chkconfig iptables on/off (永久关闭/开启)

                                           Chkconfig –list iptables (查看状态)

                                          

    三、设置代理服务器

    vi ~/.bashrc

    fi

    export http_proxy=http://admin:xmgps@10.5.16.29:808

    source ~/.bashrc   (执行脚本)

    六、关闭

    Vi /etc/selinux/config

    #SELINUX=enforcing

    SELINUX=disabled

    // setenforce 0

    // setenforce 1

    // getenforce

    四、时间同步

             Yum install –y ntp

             // rpm –qa|grep ntp*

             // rpm –qa|grep ntp

             Ntpdate 10.5.18.200

             Crontab –e

             0 */1 * * * /usr/sbin/ntpdate 10.5.18.200 >null 2>&1

             Crontab –l

    [时区在其余地区处理:

    # rm   -f /etc/localtime 
    # ln -sf  /usr/share/zoneinfo/Asia/Shanghai    /etc/localtime     

    五、zabbix安装

             // rpm –qa|grep zabbix*

             // rpm –qa|grep zabbix

             Vi /etc/resolv.conf

             Nameserver 218.85.157.99

             Yum remove zabbix-release

             // yum remove zabbix-agent

             // yum install http://repo.zabbix.com/zabbix/2.2/rhel/6/x86_64/zabbix-release-2.2-1.el6.noarch.rpm

             Rpm –ivh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm

             Rpm –ivh http://mirrors.aliyun.com/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm

             Yum install –y wget

             Rpm –ivh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-agent-3.0.12-1.el7.x86_64.rpm

    http://repo.zabbix.com/zabbix/3.0/rhel/6/x86_64/zabbix-agent-3.0.9-1.el6.x86_64.rpm

             Cd /usr/lib/system/system

             Systemctl enable zabbix-agent

             // Systemctl start zabbix-agent(启用)

             Systemctl status zabbix-agent (查询状态)

    七、检测

    其他机器:telnet IP 10050

    磁盘管理

    创建pv: pvcreate /dev/sdb1

    查看pv:  pvdisplay 或者pvscan

    创建VG: vgcreate vg_xxx /dev/sdb1

    查看vg:   vgdisplay

    拓展vg: vgextend vg_xxx /dev/sdb1

    创建lv:  lvcreate –l 5g –n lv_xxx vg_xxx

    查看lv: lvdisplay

    拓展lv: lvextend –l +100%free /dev/vg_xmxxx/lv_xxx

    #lvextend –l +5g /dev/vg_xxx/lv_xxx

    格式化lv: mkfs.ext4 /dev/vg_xxx/lv_xxx

    挂载使用:mkdir /mnt/lv_xxx

    Mount /dev/vg_xxx/lv_xxx /mnt/lv_xxx/

    Rpm –ivh http://101.96.10.65/repo.zabbix.com/zabbix/3.0/rhel/6/x86_64/zabbix-agent-3.0.5-1.el6x86_64.rpm

    # 查看网卡设备

     

    [root@localhost ~]# nmcli dev

    [root@localhost ~]# nmcli con sh

    # 删除异常网卡

     

    [root@localhost ~]# nmcli con del ens2f0

     

    # 重新添加网卡配置文件

    [root@localhost ~]# nmcli con add type ethernet con-name ens2f0 ifname ens2f0

    # 进入ens2f0网卡配置

    [root@localhost ~]#vi /etc/sysconfig/network-scripts/ifcfg-ens2f0

    #更改以下内容:

    路由找不到的话则直接添加vi /etc/sysconfig/network-scripts/route-ens2f0

    10.5.16.0/20 via 172.29.0.201 dev ens160
