mysql 5.6.38 安装（redhat 6）

本文只适用于通过 rpm 二进制的方式安装，使用源码安装的请自行百度。

1. 准备步骤

下载地址 ：https://dev.mysql.com/downloads/mysql/5.6.html

只需要以下安装文件

MySQL-client*.rpm
MySQL-devel*.rpm
MySQL-server*.rpm

需要使用 root 的账号进行操作

2. 卸载

卸载包

找出所有已经安装的包

rpm -qa | grep -i mysql

移除上面命令列出来的包

rpm -e pagename --nodeps

参数 pagename 上面出现的包名
参数 --nodeps 表示不检查依赖进行删除

删除文件

查找 mysql 的文件

find / -name mysql

删除

rm -rf folderORFileNamw

3. 安装

安装软件

依次执行

rpm -ivh MySQL-devel*.rpm
rpm -ivh MySQL-client*.rpm
rpm -ivh MySQL-server*.rpm

此时安装完成后 mysql 已经自动启动。查看是否启动成功可以使用

lsof -i:3306

来查看。

配置 my.cnf

使用命令

find / -name my-default.cnf

找到此文件。

复制配置文件到

/etc/

目录下

cp thisFilePath/my-default.cnf /etc/my.cnf

编辑修改 my.cnf 文件，只需要修改以下配置

# mysql 安装的基础目录
basedir = /usr
# mysql 数据库文件目录（默认目录）
datadir = /var/lib/mysql
# 端口（可随意修改）
port = 3306
# 大小写忽略（用于表名、字段）
lower_case_table_names=1

附上我的 my.cnf 配置

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/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
datadir = /var/lib/mysql
port = 3306
# server_id = .....
# socket = .....

# 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 = 16M
# read_rnd_buffer_size = 2M
lower_case_table_name = 1

thread_cache_size = 16
query_cache_size = 128M
max_connections = 3000

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
