配置mysql(mariadb)启动配置文件my.conf
[client]
port = #端口号
socket = #socket所在路径
[mysqld]
user = #使用哪个用户
port = #端口号
socket = #socket所在路径
basedir = #表示MySQL的安装路径
datadir = #数据库所在路径
log-bin =
server-id = 6 #表示是本机的序号为1,一般来讲就是master的意思
log-error= #错误日志
[mysqld_safe]
log-error= #错误日志
pid-file= #进程ID文件 -
初始化数据库
-
mysql_install_db --basedir=/usr/local/mysql/ --datadir=/opt/mysqld/data1 --user=mysql
-
mysqld --defaults-file=*/my.cnf --initialize --basedir=/usr/local/mysql/ --datadir=/home/mysql/data3308/data
-
-
启动mysql数据库
- mysqld_safe --defaults-file=*/my.cnf &
- mysqld --defaults-file=*/my.cnf &
-
停止mysql
systemctl stop mariadb -
测试连接数据
mysql -S */*.socket -uroot -p

以上脚本是根据一片帖子进行修改的,增加了数据库的初始化和my.conf的配置过程,但是由于后期无法找到相关帖子,特此说明!!!!!
