When compiling the go project under windowds, when you perform the following operations:
SET CGO_ENABLED = 0 set GOARCH = amd64 set GOOS = linux go build main.go
The operation of set GOOS= linux is followed by a space after the linux, the compiler cannot automatically remove the space, causing the compilation to fail.
end!
nginx: [error] open() “/usr/local/nginx/logs/nginx.pid” failed (2: No such file or directory)
This error is: the pid file is missing in the logs directory.
Solution: Re-specify the configuration file loaded at startup, and then restart. If the nginx configuration file directory is: /usr/local/nginx/conf/nginx.conf
First execute the command: /usr/local/nginx/sbin/nginx -c/usr/local/nginx/conf/nginx.conf
Then: /usr/local/nginx/sbin/nginx -s reload for smooth restart, no error will be reported
Error when installing software using yum
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
Eg. Invalid release/repo/arch combination/
removing mirrorlist with no valid mirrors: /var/cache/yum/x86_64/6/base/mirrorlist.txt
1. View yum configuration file
vim /etc/yum.repos.d/CentOS-Base.repo
2. Add a comment to the mirrorlist in the original configuration, and delete the comment from the baseurl to make it effective. Take the base module as an example, and the other modules are treated the same

baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
It still doesn’t work because the baseurl link mirror.centos.org has no resources.
3. Reconfigure the resource path https://vault.centos.org/6.8/
Modified configuration
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

rm -rf /var/cache/yum
yum makecache
Run again
Due to the configuration of oracle restart, the database instance will automatically start to read-only mode after it goes down. Data synchronization needs to be started manually. Several failures are at night. Before finding the cause, add zabbix to monitor the adg synchronization status. When the synchronization stops, it will be issued. Early warning for timely processing.
Check the database log and found the following error:
ORA-04021: timeout occurred while waiting to lock object
LGWR (ospid: 9817): terminating the instance due to error 4021
Query mos, suspected oracle bug, oracle gave a repair method, increase the shadow parameter: ALTER SYSTEM set “_adg_parselock_timeout”=550 scope=both
So adjust the parameters, restart the database, observe for a period of time, the downtime does not appear again, hereby record.

Error:
Jul 19 08:04:57 mail kernel : ACPI: No handler for Region [POWR] (ffff88012e5ad2b8) [IPMI]
Symptoms are to be seen, and the Internet says it will cause an automatic restart .
# Online collection solutions (try after the automatic restart appears)
Method 1: (to be tested)
# vi /boot/grub/grub.conf
Add intremap=off or intremap=no_x2apic_optout at the end of the kernel line
Method 2: (This method will cause multi-core to single-core, use with caution in production environment )
# vi /boot/grub/grub.conf
Add acpi=off noacip at the end of the kernel line, and turn off the advanced power management interface as follows:
kernel … acpi=off noacip
Method 3: Upgrade the kernel ( use with caution in production environment )
# yum install kernel

conda install --use-local bioconductor-genomeinfodbdata-1.2.0-r351_0.tar.bz2An error occurred when using supercomputer local installation .
The main reason is that supercomputing does not allow links to external networks, and other data will be downloaded when the package is installed, so an error occurs.
So just download the files needed by genomeinfodbdata and place them in the folder where the library is located.

Solution:
1. yarn install again (npm mirroring is not recommended for initialization, npm needs to be considered if the network is good)
2. npm start
nginx.exe -s reload execution error
wrong reason:
Nginx has not been started yet, execute the start nginx command to start Nginx
nginx.exe -s reload
So far the problem is solved
