# 启动 mysql (指定 默认 的 配置文件)
./mysqld --defaults-file=my.cnf

# 后台 启动 mysql
./mysqld --defaults-file=my.cnf &

/lyc/mysql-5.5.62/tmp/mysql.sock

 

# 安装 一定要指定 basedir 和 datadir ！

./mysql_install_db --basedir=/lyc/mysql-5.5.62 --datadir=/lyc/mysql-5.5.62/mysql-data

 

一份配置 如下- (详情参考 https://dev.mysql.com/doc/refman/5.5/en/)

# *** 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]
port=3307
socket = /lyc/mysql-5.5.62/tmp/mysql.sock  # socket 名称，如果一个服务器有多个 mysql 请务必指定此值
max_allowed_packet=2G  # 最大文件导入限制 防止 导入数据过大时出错
wait_timeout=2880000   # 防止 导入数据过大时出错 
interactive_timeout = 2880000   # 防止 导入数据过大时出错
# 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 = .....
# datadir = .....
# port = .....
# server_id = .....
# socket = .....

basedir=/lyc/mysql-5.5.62  # mysql 目录
datadir=/lyc/mysql-5.5.62/mysql-data  # mysql 数据目录

# 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.
