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
