Pagoda panel docker failed to start and yum update failed: rpmdb: BDB0113 Thread/process 2673/140126198814528 failed: BDB1507 Thread died

 If the Pagoda panel fails to start docker , first check whether there are official updates , or ask the official

If it is determined that it is not an official problem, then it may be an error in the yum command.

Use command

yum update
If the update fails, it is basically certain that the failure of docker to start is caused by yum dependencies. The prompt is as follows:

yum update failed: rpmdb: BDB0113 Thread/process 2673/140126198814528 failed: BDB1507 Thread died

Clear, execute the following commands step by step, then update yum, and finally try restarting docker

#cd /var/lib/rpm
Basenames __db. 001 __db. 003 Group Name Packages Requirename Sigmd5
Conflictname __db. 002 Dirnames Installtid Obsoletename Providename Sha1header Triggername
#rm -rf __db*
#rpm --rebuilddb

If it still doesn't work, change the source with one click and try reinstalling docker.

bash <( wget --no-check-certificate -qO-

Run the following command on the server terminal to install it.

/bin / bash /www/server/panel/install/ 0 install docker_install


But the old version of the Pagoda panel is useless no matter how much you try. The smart command terminal installs it directly.

The following are some practical notes that the author recorded during the process of learning to build docker. I also encountered some pitfalls during the process, but they were all solved. I will record them here for direct reference when building again in the future.

1. First, check the CentOS version to ensure that it is CentOS7 or above and the system kernel is above 3.10——

[ root@ 192 opt ]# uname -r
3.10 . 0 - 693. el7 . x86_64

2. Uninstall the old docker version

sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest-logrotate \
docker-logrotate \

3. Install the required dependency packages

sudo yum install -y yum-utils
4. Set up a domestic mirror warehouse

sudo yum-config-manager \
--add-repo \

5. Update the yum package index

yum makecache fast
6. Install docker-related docker-ce community docker ee enterprise version

sudo yum install docker-ce docker-ce-cli
7. Start docker

systemctl start docker
At this time, a very strange exception occurred:

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

Don’t panic, let’s check the daemon.json file format first:

vim /etc/docker/daemon.json
I found that the daemon.json file looks like this, and I don’t know why it is missing some characters after updating and downloading it directly...

It needs to be modified like this, that’s it

{"registry-mirrors": [""],
"insecure-registries": []

Next, you can start docker normally——

[root@192 opt]# systemctl daemon-reload
[root@192 opt]# systemctl start docker

If no error is reported, enter systemctl status docker.service. If the following information is displayed, the installation is started and the startup is successful:

After successful installation, when using docker version, the following information will generally appear:

[ root@ 192 opt ]# docker version

When trying to pull down hello-world, a timeout problem occurred:

[root@192 opt]# docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get "": net/http: TLS handshake timeout.
See 'docker run --help'.

At this time, you need to change the information in the daemon.json file to the domestic Alibaba Cloud image configuration, which can improve the pulling speed and avoid timeout problems, as follows:

{"registry-mirrors": [""],
"insecure-registries": []
Then, restart systemctl restart docker.

[root@192 opt]# sudo systemctl restart docker
and try to execute docker run hello-world again. This time it works fine:

[root@192 opt]# docker run hello-world
Unable to find image 'hello-world:latest' locally

After enjoying Internet services for many years, I already have countless accounts and passwords. Whether it is a website or a major app, I have registered for hundreds of services. Password management is quite a headache. Whether it is cloud notes or new text files, it is always difficult to manage. Fortunately, some browsers support account and password synchronization.

The password synchronization and filling function that comes with the Chrome browser is really good, but the browser records your password in plain text locally on the computer. Although you need to unlock the password to view the password in the Chrome browser, it is also different from those "I am full". "18 years old and enter directly" is the same decoration. Security issues have always existed and have not been solved for many years. Even Github has multiple one-click query and reading browser password tools that can be downloaded at will. This shows that the passwords of major browsers are safe. The coefficient is really low. Although Trojans in computers are extremely unlikely events, it is still very necessary to do password protection in advance to prevent problems before they happen.

If you need a password synchronization management service for iOS, Android, Windows, Mac, Linux and other platforms, as well as a password management notebook-like tool, then today’s article is very suitable. Before this, Laoye has already integrated all browsers Password data was migrated to a multi-platform service. After using it for a few days, I regretted not using it earlier.

Popular password management tools currently on the market are LastPass , 1Password , KeePass , Bitwarden, etc.

LastPass is relatively well-known, but it has repeatedly exposed major security issues. It is no longer recommended for everyone to use it, not to mention that it does not support Chinese and is paid.

1Password is good at everything, but I’m a bit reluctant to pay a few hundred dollars a year. If you have money but no brains, you can definitely get into a car.

KeePass is a high-level operation, purely localized management tool. If you don’t trust cloud services, you can consider using this. Just synchronize the encrypted local files through WebDAV or cloud disk. Generally, programmers and computer gamers like to toss with this. If you need Chinese For the client, use KeePassXC

Bitwarden is the tool introduced today. It is also our own password hosting solution. The free prostitution function is basically enough. Even if the official payment is only about 100 a year, it is very cost-effective. It supports Chinese (except the official website) and third-party Self-built cloud hosting services are basically safe enough. Bitwarden provides self-built solutions. As an open source project, it also directly increases the popularity.
