一键安装MySQL python 程序脚本
主要功能:一键安装mysl服务器端,mysql client 端。
在运行该脚本之前需要两个必要的文件
mysql.tar.gz:该文件是编译完成后的文件压缩包,需要注意的是这个压缩包不是对目录的压缩,目录下面的文件以及子目录压缩.
例如,basedir 目录是/usr/local/mysql ,不需要对整个mysql目录进行压缩, 压缩里面的文件和子目录就行了,
cd /usr/local/mysql tar -zcvf mysql.tar.gz *
解压之后是许多的文件和目录,而不是一个目录
my.cnf:配置文件模板,这个模板可以自己定义
[client]
port=3306
socket=/opt/mysql/data/mysql.sock
[mysqld]
innodb_buffer_pool_size = 512M
log_bin = /opt/mysql/binlog/binlog
join_buffer_size = 1M
sort_buffer_size = 1M
read_rnd_buffer_size = 1M
datadir= /opt/mysql/data
basedir = /usr/local/mysql
tmpdir = /opt/mysql/tmp
sql_mode=‘‘
innodb_log_file_size = 1G
以下是具体实现脚本
