I'm trying to install MySQL(pure) on Arch Linux so I downloaded the following file from https://dev.mysql.com/downloads/mysql/.
mysql-8.0.26-linux-glibc2.17-x86_64-minimal-rebuild.tar.xz
I extracted it and tried to run ./mysql_secure_installation but after I enter the root password I get the following error message:
[rob#archrob bin]$ sudo ./mysql_secure_installation
Securing the MySQL server deployment.
Enter password for user root:
Error: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
How can I fix this?
I tried to download it from AUR repository too but when I run the makepkg -si it get a point of the installation it looks like will take forever.
Build files have benn written to /home/rob/mysql/src/build
[0%] Built target INFO_BIN
[0%] built target abi_check
[0%] built target INFO_SRC
[0%] Building CXX object extra/protobuf...
[0%] and so on...
After one hour it was at [22%] so I stopped the installation and tried from the official website.
You'll need to start mariadb before running mysql_secure_installation:
$ sudo systemctl start mariadb.service

I was try to unistall and install the HomeBrew and the MYSQL again but always had the same ¡s errors.
Thanks for the help.
Not a real answer:
If it is not absolutely required for you to run it as a native process, run it in docker.
Besides that: mysql wants to run as root, as the error message says. Maybe you need to correct the mode bits. Inspect the brew post installation steps carefully, usually there is a hing or command to execute.
I am trying to setup KVM, but when running $ sudo virsh net-define br10.xml I get this:
error: failed to connect to the hypervisor
error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such file or directory
And when jumping into virt-manager GUI a get this dialog Unable to connect to libvirt qemu:///system.
I checked if I am in both kvm and libvirt groups and that seems okay.
I also checked if the libvrt-sock file is created when running $ sudo systemctl start libvirtd.service but there is nothing.
So it showed up that privilges for my files wasn't set correctly. Now everything works
I started working on ejabberd recently and ran into a problem while connecting with mysql.
I had installed ejabberd using the command line on Ubuntu - sudo apt-get install ejabberd
I had referenced the following tutorial for setting up ejabberd - Install ejabberd on Ubuntu
Now, in order to connect to Mysql I have done the following changes in ejabberd.yml -
auth_method: odbc
odbc_type: mysql
odbc_server: "localhost"
odbc_database: "ejabberd"
odbc_username: "ejabberd"
odbc_password: "password"
##
## If you want to specify the port:
odbc_port: 3306
But on restarting the service, I get this error
[critical] <0.38.0>#ejabberd:exit_or_halt:133 failed to start application 'p1_mysql': {error,
{"no such file or directory",
"p1_mysql.app"}}
I saw a few links where it was mentioned to use ./configure --enable-odbc --enable-mysql to solve this issue(works when you install ejabberd by compiling the source), but since I have not compiled the source code to install ejabberd (like I mentioned above), I am unable to do this. How do I solve this issue. Thanks in advance.
To use ejabberd with Mysql in Ubuntu you need to install the erlang-p1-mysql package:
sudo apt install erlang-p1-mysql
I had the same issue and that solved it.
Compile it from source and put resulting p1_mysql* files in the installed ejabberd's ebin directory, e.g.:
$ ./configure --enable-mysql
$ make
$ cp deps/p1_mysql/ebin/* /path/to/running/ejabberd/ebin/
I am on FreeBSD 10.2 32 bit and installed the newest version of mysql with the following command:
pkg install mysql57-server-5.7.12
Now, when I try to start mysql:
service mysql-server start
/usr/local/etc/rc.d/mysql-server: WARNING: failed precmd routine for mysql
I am getting this error. I hope you can help me.
Check your /var/db/mysql folder, if it contains files, make a backup and delete dir content:
rm -rf /var/db/mysql/*
Then do a data directory initialization:
/usr/local/libexec/mysqld --initialize --user=mysql
You should get a new temporary password, write it down, then start mysql-server
service mysql-server start
After mysql starts, secure the installation via:
/usr/local/bin/mysql_secure_installation
Open /etc/rc.conf and append or modify this line :
mysql_enable="YES"
Save the file, close it and retry to start the server.
i am trying to setup mysql-proxy on ubuntu on amazon ec2
i have done following:
sudo apt-get install mysql-proxy --yes
vi /etc/default/mysql-proxy
i put following content on "/etc/default/mysql-proxy"
ENABLED="true"
OPTIONS="--proxy-lua-script=/usr/share/mysql-proxy/rw-splitting.lua
--proxy-address=127.0.0.1:3306
--proxy-backend-addresses=private_ip_of_another_ec2_db_server:3306,private_ip_of_another_ec2_db_server:3306"
also tied with "--proxy-address=private_ip_or_public_ip_of_proxy-server:3306 or 4040"
and "--proxy-backend-addresses=public_ip_of_another_ec2_db_server:3306,public_ip_of_another_ec2_db_server:3306"
after that i tried to connect proxy server from another pc using mysql like:
mysql -u some_user -pxxxxx -h proxy_server_ip
or
mysql -u some_user -pxxxxx -h proxy_server_ip -P 4040
but its not working
its showing error:
ERROR 2003 (HY000): Can't connect to MySQL server on 'ip' (10061)
i want to tell you can connect the db server remotely where i allowed remote connection to any host
i also tried /etc/init.d/mysql-proxy start or /etc/init.d/mysql-proxy restart but no result
just to inform you that /etc/init.d/mysql-proxy stop is showing failed
can anyone please help me to setup and configure mysql-proxy on ubuntu
===
Edit
i found some help from other question of stackoverflow and also according to a suggestion in the comments, have done following procedure. and it seems its working now.
i installed mysql-client and mysql-server locally(on proxy server)
then i tried to run mysql-proxy using following command:
mysql-proxy --proxy-backend-addresses=10.73.151.244:3306 --proxy-backend-addresses=10.73.198.7:3306 --proxy-address=:4040 --admin-username=root --admin-password=root --admin-lua-script=>/usr/lib/mysql-proxy/lua/admin.lua
then i tried to connect remotely to the proxy server and its working.
but it seems i need to run this command under screen because when i close the terminal proxy stops working.
Can you please tell me that do i need to run this command under screen or is there any other way to make it alive all time?
There is no need to install Mysql client or Mysql Server on your mysql-proxy.
Installing mysql-proxy does have "full daemon capabilities" compiled into it.
If your are running Ubuntu Server, you may wish to use an UPSTART service script.
This script can be copied into /etc/init/mysql-proxy.conf
# mysql-proxy.conf (Ubuntu 14.04.1) Upstart proxy configuration file for AWS RDS
# mysql-proxy - mysql-proxy job file
description "mysql-proxy upstart script"
author "shadowbq <shadowbq#gmail.com>"
# Stanzas
#
# Stanzas control when and how a process is started and stopped
# See a list of stanzas here: http://upstart.ubuntu.com/wiki/Stanzas#respawn
# When to start the service
start on runlevel [2345]
# When to stop the service
stop on runlevel [016]
# Automatically restart process if crashed
respawn
# Essentially lets upstart know the process will detach itself to the background
expect daemon
# Run before process
pre-start script
[ -d /var/run/mysql-proxy ] || mkdir -p /var/run/mysql-proxy
echo "starting mysql-proxy"
end script
# Start the process
exec /usr/bin/mysql-proxy --plugins=proxy --proxy-lua-script=/usr/share/mysql-proxy/rw-splitting.lua --log-level=debug --proxy-backend-addresses=private_ip_of_another_ec2_db_server:3306,private_ip_of_another_ec2_db_server:3306 --daemon --log-use-syslog --pid-file=/var/run/mysql-proxy/mysql-proxy.pid
In the above example I hard coded the AWS RDS server into script, instead of fiddling with defaults and config file
Install Upgraded version 0.8.5
Note:
apt repo does not have 0.8.5 so we need to download tar from mysql official site
Prerequisite :-
Create file /etc/default/mysql-proxy with following content
ENABLED="true"
OPTIONS="--defaults-file=/etc/mysql/mysql-proxy.cnf"
Installation Procedure :-
Download mysql-proxy 0.8.x
Untar in /usr/local
Update PATH environment with /usr/local/mysql-proxy-0.8.5-linux-debian6.0-x86-64bit/bin
vim /etc/environment (to update environment path)
cd /usr/local/mysql-proxy-0.8.5-linux-debian6.0-x86-64bit/bin
Run command sudo ./mysql-proxy --defaults-file=/etc/mysql/mysql-proxy.cnf
Sample mysql-proxy.cnf file
[mysql-proxy]
log-level=debug
log-file=/var/log/mysql-proxy.log
pid-file = /var/run/mysql-proxy.pid
daemon = true
--no-proxy = false

proxy-address=0.0.0.0:4040
admin-address=localhost:4041
change host ip and port of RDS or mysql
connect to Mysql server via proxy with
mysql -h{proxy-host-ip} -P 4040 -u{mysql_username} -p
