[Solved] Minidlna Error: checking for avformat_open_input in -lavformat -lavcodec -lavutil -lz… no

I have installed FFmpeg, but when I configured minidlna1.3.0, I found an error when I executed. /configure and found an error
checking for avformat_open_input in -lavformat -lavcodec -lavutil -lz… no
configure: error: Could not find libavformat – part of ffmpeg
Opening the configuration results file config.log reveals various errors.
For example.
libavformat/rtmpproto.c:1077: undefined reference to ‘inflateInit_’
libavcodec/vaapi_encode_h264.c:871: Undefined reference to ‘vaQueryVendorString’.

So the configure file needs to be modified

as_ac_Lib=`$as_echo "ac_cv_lib_avformat -lavcodec -lavutil -lz''_av_open_input_file" | $as_tr_sh`
modify to
as_ac_Lib=`$as_echo "ac_cv_lib_avformat -lavcodec -lavutil -lz -lm -lbz2 -lswresample -llzma -lX11 -lva -lva-x11 -lva-drm''_avformat_open_input" | $as_tr_sh`

LIBS="-lavformat -lavcodec -lavutil -lz  $LIBS"
modify to
LIBS=" -lpthread -lavformat -lavcodec -lavutil -lz  -lm -lbz2 -lswresample -llzma -lX11 -lva -lva-x11 -lva-drm $LIBS"

if test x"$ac_cv_lib_avformat__lavcodec__lavutil__lz___av_open_input_file" != x"yes" &&
test x"$ac_cv_lib_avformat__lavcodec__lavutil__lz___avformat_open_input" != x"yes"; then
modify to
if eval test \"x\$"$as_ac_Lib"\" != x"yes"; then

SSH keygen (option)

-b: specify the length of the key. 
-e : read the private or public key file of openssh. 
-C: add comment. 
-f: specify the name of the file used to save the key. 
-i : reads the unencrypted ssh-v2 compatible private/public key file and then displays the openssh compatible private/public key on the standard output device.

Cannot find module ‘.. / lib / utils / unsupported. JS’ problem in installing node in centos7

When installing node in centos7 virtual machine, an error is reported: cannot find module ‘…/lib/utils/unsupported. JS’. The complete error is as follows:

the prompt is that an unsupported.js file cannot be found. Finally, it is found that the soft connection is wrong when installing this version of node in centos7, This problem may not be solved by re installation (at present, I only encounter this problem in the virtual machine of centos7). Delete the original NPM connection and re create one.

1. First, download the CD to the bin folder of the node version, where version 12.16.2 is installed

cd /opt/node-v12.16.2-linux-x64/bin

2. Delete the NPM file in the path, and enter yes when prompted

rm npm

3. Reestablish file connection

ln -s ../lib/node_modules/npm/bin/npm-cli.js ./npm

Using NPM – V command again, it is found that it is almost OK.
the whole operation is shown as follows:

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

terms of settlement:

Just run the following three instructions

ed -i "s|enabled=1|enabled=0|g" /etc/yum/pluginconf.d/fastestmirror.conf
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
curl -o /etc/yum.repos.d/CentOS-Base.repo https://www.xmpan.com/Centos-6-Vault-Aliyun.repo

There is another solution in the original, but I solved it with the first one. If you can’t solve it with this method, you can try the second one in the original https://blog.csdn.net/weixin_ 45621658/article/details/110734514

[Solved] ln: failed to create symbolic link ‘/usr/bin/java’: File exists

MySql Install Error: Can‘t connect to local MySQL server through socket ‘/tmp/mysql.sock‘

@[TOC] (error 2002 (HY000): can’t connect to local MySQL server through socket ‘/ TMP/MySQL. Socket’)

System overview

CentOS 7 + MySql-community-release-el6-5.noarch。

Install MySQL process

First, download the RPM installation package as follows:
WGet – P/usr/software/ http://repo.mysql.com/mysql-community-release-el-5.noarch.rpm
Then, run the following command to install the yum source:
RPM – IVH mysql-community-release-el-5. Noarch. RPM
after the yum source is installed, you can view it as follows:
ll/etc/yum. Repos. D/
if the yum source is installed correctly, It should be displayed:

– rw-r – r–. 1 root 616 November 23 2020 centos-x86_ Next, run the following command to install MySQL:
Yum – y install MySQL
at the end of the process, Run the following command to start MySQL service and report an error:
Service mysqld start
at this time, the error content is as shown in the question. After checking the above installation process with the following command, the packages to be installed are:
RPM – QA | grep MySQL
the packages to be seen at this time are as follows:
mysql-community-release-el6-5. Noarch
mysql-community-common-5.6.51-2. El6.x86_ 64
mysql-community-client-5.6.51-2.el6.x86_ 64
mysql-community-libs-5.6.51-2.el6.x86_ 64
you can see that there is no MySQL Server package in the above package. So next, install MySQL server with the following command:
Yum – y install MySQL server
after the above command is executed successfully, start MySQL service:
Service mysqld start
and then run:
MySQL – uroot to enter MySQL server.

Resolving yum source-related issues: Cannot retrieve metalink for repository: epel/x86_64. Please verify its path and try again

Loaded plug-ins: fastestmirror
Loading mirror speeds from cached hostfile
One of the configured repositories failed (none),
and yum doesn’t have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work “fix” this:

 1. Contact the upstream for the repository and get them to fix the problem.

 2. Reconfigure the baseurl/etc. for the repository, to point to a working
    upstream. This is most often useful if you are using a newer
    distribution release than is supported by the repository (and the
    packages for the previous distribution release still work).

 3. Run the command with the repository temporarily disabled
        yum --disablerepo=<repoid> ...

 4. Disable the repository permanently, so yum won't use it by default. Yum
    will then just ignore the repository until you permanently enable it
    again or use --enablerepo for temporary usage:

        yum-config-manager --disable <repoid>
    or
        subscription-manager repos --disable=<repoid>

 5. Configure the failing repository to be skipped, if it is unavailable.
    Note that yum will try to contact the repo. when it runs most commands,
    so will have to try and fail each time (and thus. yum will be be much
    slower). If it is a very temporary problem though, this is often a nice
    compromise:

        yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
