导读:mysql5.6单实例安装: 1.下载二进制安装包 mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz tar -xvf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz 2.拷贝安装包和配置文件(如果没有特殊情况,将安装包解压放置在该目录) cp -rf mysql /usr/local/mysql cp -r
        mysql5.6单实例安装:

1.下载二进制安装包
      mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
     tar -xvf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
 
2.拷贝安装包和配置文件(如果没有特殊情况,将安装包解压放置在该目录)
     cp -rf mysql /usr/local/mysql
     cp -rf my5.6.cnf /etc/my.cnf
 
3.创建mysql用户
useradd mysql
 
4.添加数据目录
mkdir -p /home/mysql3306/mysql3306
mkdir -p /home/mysql3306/logs
 
5.修改目录权限
chown mysql:mysql -R /home/mysql3306
 
6.修改配置文件
socket          = /tmp/mysql.sock(socket文件存放位置)
datadir         = /home/mysql3306/mysql3306(数据文件存放目录)
server-id               = 12013306(设置serverid 命名规则:ip后两位+端口号)
port            = 3306(启动端口)
innodb_buffer_pool_size         = 1024M(innodb buffer pool大小)
*如果是核心节点单实例 配置成系统总内存的75%左右,如果不是核心节点则按照具体业务压力来设置
 
7.初始化数据库(确认2个OK)

# /usr/local/mysql/bin/mysql --help

Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved.

Usage: /usr/local/mysql/bin/mysql [OPTIONS] [database]
-?, --help Display this help and exit.
-I, --help Synonym for -?
--auto-rehash Enable automatic rehashing. One doesn't need to use
'rehash' to get table and field completion, but startup
and reconnecting may take a longer time. Disable with
--disable-auto-rehash.
(Defaults to on; use --skip-auto-rehash to disable.)
-A, --no-auto-rehash
No automatic rehashing. One has to use 'rehash' to get
table and field completion. This gives a quicker start of
mysql and disables rehashing on reconnect.
--auto-vertical-output
Automatically switch to vertical output mode if the
result is wider than the terminal width.
-B, --batch Don't use history file. Disable interactive behavior.
(Enables --silent.)
--bind-address=name IP address to bind to.
-b, --binary-as-hex Print binary data as hex
--character-sets-dir=name
Directory for character set files.
--column-type-info Display column type information.
-c, --comments Preserve comments. Send comments to the server. The
default is --skip-comments (discard comments), enable
with --comments.
-C, --compress Use compression in server/client protocol.
-#, --debug[=#] This is a non-debug version. Catch this and exit.
--debug-check Check memory and open file usage at exit.
-T, --debug-info Print some debug info at exit.
-D, --database=name Database to use.
--default-character-set=name
Set the default character set.
--delimiter=name Delimiter to be used.
--enable-cleartext-plugin
Enable/disable the clear text authentication plugin.
-e, --execute=name Execute command and quit. (Disables --force and history
file.)
-E, --vertical Print the output of a query (rows) vertically.
-f, --force Continue even if we get an SQL error.
-G, --named-commands
Enable named commands. Named commands mean this program's
internal commands; see mysql> help . When enabled, the
named commands can be used from any line of the query,
otherwise only from the first line, before an enter.
Disable with --disable-named-commands. This option is
disabled by default.
-i, --ignore-spaces Ignore space after function names.
--init-command=name SQL Command to execute when connecting to MySQL server.
Will automatically be re-executed when reconnecting.
--local-infile Enable/disable LOAD DATA LOCAL INFILE.
-b, --no-beep Turn off beep on error.
-h, --host=name Connect to host.
-H, --html Produce HTML output.
-X, --xml Produce XML output.
--line-numbers Write line numbers for errors.
(Defaults to on; use --skip-line-numbers to disable.)
-L, --skip-line-numbers
Don't write line number for errors.
-n, --unbuffered Flush buffer after each query.
--column-names Write column names in results.
(Defaults to on; use --skip-column-names to disable.)
-N, --skip-column-names
Don't write column names in results.
--sigint-ignore Ignore SIGINT (CTRL-C).
-o, --one-database Ignore statements except those that occur while the
default database is the one named at the command line.
--pager[=name] Pager to use to display results. If you don't supply an
option, the default pager is taken from your ENV variable
PAGER. Valid pagers are less, more, cat [> filename],
etc. See interactive help (h) also. This option does not
work in batch mode. Disable with --disable-pager. This
option is disabled by default.
-p, --password[=name]
Password to use when connecting to server. If password is
not given it's asked from the tty.
-P, --port=# Port number to use for connection or 0 for default to, in
order of preference, my.cnf, $MYSQL_TCP_PORT,
/etc/services, built-in default (3306).
--prompt=name Set the mysql prompt to this value.
--protocol=name The protocol to use for connection (tcp, socket, pipe,
memory).
-q, --quick Don't cache result, print it row by row. This may slow
down the server if the output is suspended. Doesn't use
history file.
 
--net-buffer-length=#
The buffer size for TCP/IP and socket communication.
--select-limit=# Automatic limit for SELECT when using --safe-updates.
--max-join-size=# Automatic limit for rows in a join when using
--safe-updates.
--secure-auth Refuse client connecting to server if it uses old
(pre-4.1.1) protocol.
(Defaults to on; use --skip-secure-auth to disable.)
--server-arg=name Send embedded server this as a parameter.
--show-warnings Show warnings after every statement.
--plugin-dir=name Directory for client-side plugins.
--default-auth=name Default authentication client-side plugin to use.
--histignore=name A colon-separated list of patterns to keep statements
from getting logged into mysql history.
--binary-mode By default, ASCII '' is disallowed and 'rn' is
translated to 'n'. This switch turns off both features,
and also turns off parsing of all clientcommands except
C and DELIMITER, in non-interactive mode (for input
piped to mysql or loaded using the 'source' command).
This is necessary when processing output from mysqlbinlog
that may contain blobs.
--connect-expired-password
Notify the server that this client is prepared to handle
expired password sandbox mode.
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/local/mysql/etc/my.cnf ~/.my.cnf
The following groups are read: mysql client
The following options may be given as the first argument:
--print-defaults Print the program argument list and exit.
--no-defaults Don't read default options from any option file,
except for login file.
--defaults-file=# Only read default options from the given file #.
--defaults-extra-file=# Read this file after the global files are read.
--defaults-group-suffix=#
Also read groups with concat(group, suffix)
--login-path=# Read this path from the login file.
Variables (--variable-name=value)
and boolean options {FALSE|TRUE} Value (after reading options)
