It is very troublesome to set up the development and test environment. The company’s development and test server is poisoned to do data recovery. By the way, we can arrange the way of setting up.
I am a programmer, Linux system knowledge is relatively weak, so the system security aspect is not covered in this paper, please make security policy accordingly.
The e Intranet server was exposed to the public network using FRP, resulting in mining. The FRP is still not safe, now it can only be opened when it needs to be penetrated, other times
Shut down.

Basic Installation Commands
Some commands may not be installed by default. If the commands cannot be used, perform the following steps to install the commands.
Install the ifconfig
The IP addr command is used to query network information in centos 7
If you still want ifconfig
Install.net – tools
yum install net-tools
Install vim
yum install vim
The network configuration
In VM mode, change the network mode of the VM box to bridge.
Change the hostname
To view the hostname
[root@zhirui-base ~]# hostnamectl Static hostname: zhirui-base Icon name: computer-vm Chassis: vm Machine ID: c9cea1249eaf47379236a0ed4e371584 Boot ID: 94a2959e5c684c94ad6e4e4b096af282 Virtualization: kvm Operating System: CentOS Linux 7 (Core) CPE OS Name: CPE :/ O: CentOS: CentOS :7 Kernel: Linux 3.10.0-957.el7.x86_64 Architecture: x86-64Copy the code
To view only static, transient, or flexible host names, use the “–static”, “– TRANSIENT”, or “–pretty” options respectively
Change hostname and exit the connection

If you only want to change a specific host name (static, transient or flexible), you can use the “–static”, “–transient” or “–pretty” options.

Modify the hosts
[root@zhirui-test ~]# vim /etc/hosts
127.0.0.1 zhirui-test localhost
#127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain
::1 localhost localhost.localdomain localhost6 localhost6.localdomai
Copy the code
When changing static/transient host names, any special characters or whitespace characters are removed, and any uppercase letters in supplied parameters are automatically converted to lowercase. Once the static hostname is changed, /etc/hostname is automatically updated. However, /etc/hosts will not be updated to save the changes, so you must manually update /etc/hosts every time you change the host name before restarting CentOS 7. Otherwise, the system will be slow to restart.
Changing an IP Address
By default, the server uses DHCP to obtain the address. The address can change at any time, so you need to change it to a fixed address for easy management.
Command as follows:
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-enp0s3Copy the code
Run the following command to restart the nic: service network restart
You just need to make sure that the configuration in the annotation exists, and everything else doesn’t have to be the same.
TYPE="Ethernet" PROXY_METHOD="none" BROWSER_ONLY="no" BOOTPROTO="static" The default mode is DHCP. IPADDR="192.168.1.254" ### IP address of the NETWORK adapter BROADCAST-"192.168.1.255" ### subnet BROADCAST address GATEWAY="192.168.1.1" ### GATEWAY address DNS1="192.168.1.1" ###DNS address DEFROUTE="yes" IPV4_FAILURE_FATAL="no" IPV6INIT="yes" IPV6_AUTOCONF="yes" IPV6_DEFROUTE="yes" IPV6_FAILURE_FATAL="no" IPV6_ADDR_GEN_MODE="stable-privacy" NAME="enp0s3" UUID=" 226a0688-3a2F-4485-9694-d8FEa85694AD "DEVICE=" enp0S3" ONBOOT="yes" # UUID=" 226a0688-3a2F-4485-9694-d8FEa85694AD "DEVICE=" ENp0S3" ONBOOT="yes" # UUID=" 226a0688-3a2F-4485-9694-d8FEa85694ad "DEVICE=" enP0S3" ONBOOT="yes" # The default setting is yes.Copy the code
Run the ifconfig or IP addr command to view the configured IP address:
Run the systemctl enable sshd.service command to add the SSH service to the automatic startup list
$ systemctl enable sshd.serviceCopy the code
Modify the DNS

docker
Docker-io is the previous earlier version, version number is 1., the latest version is 1.13, and docker-CE is the new version, divided into community version docker-CE and enterprise version docker-EE, version number is 17., the latest version is 17.12. The enterprise version costs a fee.
Prerequisites for installation
A static IP address is configured and the DNS is configured. If no, refer to
To uninstall the previous version, use the following methods:
-D background running container; –name Specifies the container name. -p Specifies the port on which the service runs (5672: application access port; 15672: Console Web port number); -v Mapping directory or file. (one important thing about RabbitMQ is that it stores data according to what is called a “node name”, which is the hostname by default); -e Specifies the environment variable. RABBITMQ_DEFAULT_VHOST: specifies the default VM name. RABBITMQ_DEFAULT_USER: default user name. RABBITMQ_DEFAULT_PASS: password for the default user name); — Privileged =true Does -v directory mapping, which may result in no privileged.
Use the docker ps command to view the running container

Configure the warehouse address
When Jenkins was building, I configured the following two warehouses at the same time. The private server private JAR needed by the program kept running to Ali Cloud to download, and then prompted that it could not be downloaded. If this happens, try keeping only the private server’s warehouse address.
