Linux Common Tips

First, set the fixed IP address
1.config See which NIC is used
This is supposed to be eth1.
2. Modify the DNS address
Vim/etc/resolv.conf
Search domain Address
NameServer 192.168.3.2 #主dns地址
NameServer 14.114.114.114 #次dns地址
3 Modify Ifcfg-eth1 File
Vim/etc/sysconfig/network-scripts/ifcfg-eth1
The next few items that must be set
Device=eth1
ipaddr=192.168.3.128
netmask=255.255.255.0 #子网掩码
gateway=192.168.3.2 #网关地址
Onboot=yes #引导时是否激活设备
Bootroto=static #设置ip地址为静态
dns1=192.168.3.2
4. Restart the NIC
Service Network

Second, add the command path to the $path variable
1. Modify the profile file
Vim/etc/profile
In the last line, add the PHP command line directory path modified to:
Export path= "$PATH:/usr/local/bin:/data/local/php/bin"
2. Make the file changes effective immediately
Source/etc/profile
So we can use it directly.
Php-v to see the PHP version.

Third, set up a soft link to achieve direct use of the command
1. If the Luajit installation path is
/usr/local/bin/luajit-2.1.0-beta1
View version can be
/usr/local/bin/luajit-2.1.0-beta1-v
2. Now create a soft link to execute directly from a command
Note: It is important to note that if you want to execute the command directly, you must create the/bin directory under the root directory to
The specific actions are:
Ln/usr/local/bin/luajit-2.1.0-beta1/bin/luajit
Luajit-v can also view the version, can be directly operated
