Ubuntu调教日志

Posted on 2021-01-14，7 min read

前言

  • 此记录为Linux的一个调教记录，方便以后查看

基本篇

设置软件源

  • 由于Ubuntu自带的源是国外的，所以同步的时候会比较慢。因此一般都需要修改源。由于Ubuntu自带gedit，所以就不用vi来编辑了。
 sudo gedit /etc/apt/sources.list

然后注释原来的源。添加阿里的源。

deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse

因为以后需要添加Deepin的软件。所以多添加一个deepin的源。

deb http://packages.deepin.com/deepin stable main contrib non-free
#deb-src http://packages.deepin.com/deepin stable main contrib non-free

添加完成后保存退出。

sudo apt update

等待更新完成。

环境篇

  • 由于大部分的环境能直接apt安装。我就不自己配置了。

Java

以下是apt支持的Java版本。直接输入后就能安装了（注：是openjdk不是Hotpot的JDK）。

sudo apt install default-jre              # version 2:1.11-72, or
sudo apt install openjdk-11-jre-headless  # version 11.0.7+10-3ubuntu1
sudo apt install openjdk-13-jre-headless  # version 13.0.3+3-1ubuntu2
sudo apt install openjdk-14-jre-headless  # version 14.0.1+7-1ubuntu1
sudo apt install openjdk-8-jre-headless   # version 8u252-b09-1ubuntu1

Mysql

终端中输入命令：

sudo apt install mysql-server

Mysql的常见路径

/usr/bin                 客户端程序和脚本  
/usr/sbin                mysqld 服务器  
/var/lib/mysql           日志文件，数据库  ［重点要知道这个］  
/usr/share/doc/packages  文档  
/usr/include/mysql       包含( 头) 文件  
/usr/lib/mysql           库  
/usr/share/mysql         错误消息和字符集文件  
/usr/share/sql-bench     基准程序

无法访问

  • 出现类似ERROR 1045 (28000): Access denied for user 'gloduck'@'localhost' (using password: NO)的提示。一是设置密码（默认没有密码），二是跳过密码验证

跳过密码验证：
进入配置文件

sudo gedit /etc/mysql/mysql.conf.d/mysqld.cnf

[mysqld]下添加skip-grant-tables

#
# The MySQL database server configuration file.
#
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# Here is entries for some specific programs
# The following values assume you have at least 32M ram

[mysqld]
skip-grant-tables
#
# * Basic Settings
#
user		= mysql
# pid-file	= /var/run/mysqld/mysqld.pid
# socket	= /var/run/mysqld/mysqld.sock
# port		= 3306
# datadir	= /var/lib/mysql


# If MySQL is running as a replication slave, this should be
# changed. Ref https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_tmpdir
# tmpdir		= /tmp
#
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address		= 127.0.0.1
mysqlx-bind-address	= 127.0.0.1
#
# * Fine Tuning
#
key_buffer_size		= 16M
# max_allowed_packet	= 64M
# thread_stack		= 256K

# thread_cache_size       = -1

# This replaces the startup script and checks MyISAM tables if needed
# the first time they are touched
myisam-recover-options  = BACKUP

# max_connections        = 151

# table_open_cache       = 4000

#
# * Logging and Replication
#
# Both location gets rotated by the cronjob.
#
# Log all queries
# Be aware that this log type is a performance killer.
# general_log_file        = /var/log/mysql/query.log
# general_log             = 1
#
# Error log - should be very few entries.
#
log_error = /var/log/mysql/error.log
#
# Here you can see queries with especially long duration
# slow_query_log		= 1
# slow_query_log_file	= /var/log/mysql/mysql-slow.log
# long_query_time = 2
# log-queries-not-using-indexes
#
# The following can be used as easy to replay backup logs or for replication.
# note: if you are setting up a replication slave, see README.Debian about
#       other settings you may need to change.
# server-id		= 1
# log_bin			= /var/log/mysql/mysql-bin.log
# binlog_expire_logs_seconds	= 2592000
max_binlog_size   = 100M
# binlog_do_db		= include_database_name
# binlog_ignore_db	= include_database_name

重启mysql
