学以致用二十七-----Centos7.5二进制安装mysql5.7.23

首先去官网查看mysql版本。才一个礼拜不到，我之前下载的是mysql5.7.23，现在在官网页面已然找不到了，只有5.7.24版本，不得不说更新真快。不过我下载的是mysql5.7.23，所以还是安装的是5.7.23

下载地址：https://www.mysql.com/downloads/

----------------------->  

下载下来后，比较坑的是。竟然没有源码编译安装的版本了，只有二进制版本。好吧，安装确实也比编译安装快了。。。。。

也是写了脚本来安装，自从shell脚本入门后，就要多尝试写脚本，加深印象。虽写的很low，希望之后装mysql8.0能复用

脚本运行效果

说明：mysql初始化后，会提供一个临时密码。需要记录下来

mysql 启动成功，但是进mysql的时候，报错

原因是my.cnf里[mysql] 和[client] 没有指定socket路径。很坑爹的是，我安装的这版连my.cnf也没有了。还是到网上下的模板

# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
 basedir = /usr/local/mysql
 datadir = /var/lib/mysql
 port = 3306
# server_id = .....
 socket = /tmp/mysqld.sock

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_ZERO_DATE,NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER
explicit_defaults_for_timestamp=true

[client]
default-character-set = utf8
socket = /tmp/mysqld.sock

[mysql]
default-character-set = utf8
socket = /tmp/mysqld.sock

sql_mode没有指定的话，初始化的时候会有警告

开启查询缓存

explicit_defaults_for_timestamp=true

第一次进mysql，用临时密码进去后，会提示更改密码

mysql> SET PASSWORD = PASSWORD('123456') ;

Query OK, 0 rows affected, 1 warning (0.01 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

好像在8.0版本重设密码是，以后要实践一下

mysql> SET PASSWORD = '123456';

Query OK, 0 rows affected (0.01 sec)

至此简单的mysql就安装完毕。当然还有很多配置，需要在my.cnf中去配置。
