Install CentOS7 in VMware (set static IP address) and install mySql database through docker container (super detailed tutorial)

A sophomore asked me how to install and configure these. I made a simple tutorial, recorded it here, and shared it with friends in need.

The installation process is sufficient for learning and use, and some tedious configurations in actual work are skipped!

Open the VM virtual machine, menu bar [File] -> select [New Virtual Machine], select "o Custom (Advanced)" -> [Next]

By default, keep clicking [Next] until you reach the installation disk selection location, select the official DVD image file you have downloaded (do not use other images to avoid unnecessary

pit)

[Next] Set the virtual machine name (give it a suitable name and set the appropriate path)

The processor is set to default. After installing the virtual centos, you can adjust it according to the situation. It is not necessary to set it at this time.

The memory settings are default and will be adjusted later based on usage

[Next] Select the network type and use the "NAT" network mode. This is required if CentOS needs to configure a static IP address. If you do not need to configure a static IP address, select "Bridge". It is recommended to select "NAT"

Always press [Next] to "Select Disk", and select "Create a new virtual disk" by default.

[Next] "Specify disk capacity", change the default value 20 to 10, and increase it later if it is not enough

Default【Next】Finally click "Finish"

After clicking [Finish], the installation wizard will appear. For learning purposes, it is recommended that you select "Chinese" language to avoid pitfalls. However, English is generally recommended, after all, you are a programmer

Click [Continue]

Click "Software Selection", select "o Server with GUI", and do not check the accessory options on the right for the time being. It is recommended to learn to use the GUI for personal PC to avoid pitfalls and bury yourself. Those who like to torture themselves can choose the minimum installation, and those who like to tinker can choose any one

Click [Finish] to exit. Click "Installation Location", set the default settings, and then click [Finish] to exit.

Click "Network and Hostname", turn on the Ethernet switch, and set the hostname yourself. Don’t touch the configuration options yet.

After configuration is completed, click [Start Installation], click "Root Password" to set the password to 123456 (do not set it too complicated), and click the [Finish] button twice to exit. Click "Create User", set the user and password (don't make it too complicated), and check "Make this user an administrator". Wait for the installation to complete~~~~

After the installation is complete, click [Restart] and wait for it to start by itself

After restarting, the "Initial Settings" pops up. Click to enter, check the "I Agree to the Agreement" check box, and click the "Finish" button to jump out. Finally, click "Finish Configuration" in the lower right corner.

The login user listed on the interface is the user we created earlier. We log in as the root user and click "Not Listed"

Enter the username "root", enter the previously set password 123456, confirm the login and enter the system interface "Forward"--》"Forward"--》"Skip"

Click "Applications" in the upper left corner and select "Terminal"

Open a Terminal window and enter ifconfig

ens33 is the default network connection name, and there is no IP address. At this time, whether you ping the host machine's IP or ping Baidu's website, you can't ping it.

Configure the network connection of virtual centos7

Select "Edit" - "Virtual Network Editor"

Click [Change settings]

In the figure below, select the "NAT Mode" column in the list above the pop-up window, and set the subnet IP to 192.168.xxx.0. xxx should not be set the same as the host machine. For example, if the host machine IP is 192.168.1.123, then xxx should not be equal to 1. If the host machine IP is similar to 170.20.12.14, then xxx can be set at will. (It is recommended not to set xxx to 0 or 1, but to set it to 110, 111 or other similar numbers. When the host machine is connected to different WiFi (routers), the IP change may cause the xxx value of "subnet ip" to be the same as that of the host machine. If they are the same, modify the xxx value of "subnet ip" to avoid the same.)

Click the [NAT Settings (S)...] button to set the gateway IP. The first three segments of the gateway IP should be the same as the subnet IP. The last segment should be different from the subnet IP. Finally, click "Confirm" - "Apply" - "Confirm"

Next, edit the configuration file and open a Terminal window.

Enter: vim /etc/sysconfig/network-scripts/ifcfg-eno33 to modify the configuration file

Once in the file, press a to enter edit mode

Modify and add configuration, as shown in red

After the modification is completed, press the "ESC key" - enter ":wq" in the terminal window, click the Enter key to save and exit the editing restart service: service network restart enter: ifconfig to view the network information, you can see that our static IP setting is successful

ping Baidu can ping successfully. (Ctrl+z to exit ping)

The host machine can also ping the virtual centos7

If the virtual centos7 fails to ping Baidu, set:

Select the correct network adapter vmnet8 is the network adapter for NAT settings, right click "Properties"

Check whether the IPv4 IP address of the VMnet8 network adapter is customized. The customized IP address cannot be the same as the gateway configured by VMware (192.168.11.1) or the static IP address configured in the virtual centos7 (192.168.11.101).

Then ping Baidu in the virtual centos and you will be able to ping

Finally, no matter which new WiFi (router) the host machine is connected to, the IP address of the virtual centos7 remains fixed.

Install Docker

1. Log in with root privileges and update yum (make sure the network speed meets the update requirements before updating). Generally, yum is only updated on personal systems, and the production environment should not be updated at will.

Terminal input:

yum update

3. If an error occurs:

Package does not match intended download indicates a version conflict during the update. In this case, execute: yum clean all

4. Uninstall the old version:

yum remove docker docker-common docker-selinux docker-engine

5. Install the required software packages:

yum install -y yum-utils device-mapper-persistent-data lvm2

6. Set up the yum source (Ali's source, faster)

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

7. Installation: (Since only the stable repository is enabled by default in the repo, the latest stable version 17.12.0 is installed here) yum install docker-ce Start and add it to the boot

8. Start: systemctl start docker systemctl enable docker

Verify that the installation is successful (the presence of client and service parts indicates that the docker installation and startup are successful)

docker version

Docker installs mysql

1. Terminal naming symbol: docker search mysql

2. Pull the mysql image

docker pull mysql:5.6

3. Configure MySQL

Name symbol:

docker run -p 3306:3306 --restart=always --name mysql-demo -v /usr/local/gourd/docker/mysql/conf:/etc/mysql/conf.d -v /usr/local/gourd/docker/mysql/logs:/logs -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.6 

Command Explanation:

-p 3306:3306: Maps port 3306 of the container to port 3306 of the host.

--restart=always When Docker is restarted, the container will also be restarted

--name mymysql gives the container a name

-v $PWD/conf:/etc/mysql/conf.d: Mount conf/my.cnf in the current directory of the host to /etc/mysql/my.cnf in the container.

-v $PWD/logs:/logs: mounts the logs directory under the current directory of the host to the /logs of the container.

-v $PWD/data:/var/lib/mysql : Mount the data directory under the current directory of the host to /var/lib/mysql of the container.

-e MYSQL_ROOT_PASSWORD=123456: Initialize the root user's password.

4. Name symbol: docker start (image-name) starts the image

Name symbol: docker ps -s to view the running image

Use Navicat to connect to mysql:
