Linux下自己创建目录/tigger
上传mysql压缩包到此目录
[root@localhost tigger]# tar zxvf mysql.tar.gz
[root@localhost tigger]# cp -r mysql /usr/local/mysql
/usr/local/mysql 为安装目录
cd /usr/local/mysql
[root@localhost mysql]# groupadd mysql
[root@localhost mysql]# useradd -g mysql mysql
[root@localhost mysql]# chown -R mysql .
[root@localhost mysql]# chown -R root .
[root@localhost mysql]# ./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
拷贝mysql.server文件到/etc/rc.d/init.d/并且命名为mysqld。mysql.server这个文件相当重要,是mysql的设置,可以多看看
[root@localhost mysql]# cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld
设置权限为755,不然启动mysql会失败的
[root@localhost mysql]# chmod 755 /etc/rc.d/init.d/mysqld
启动mysql:
[root@localhost bin]# service mysqld start
结果失败:
[root@localhost bin]# service mysqld start
Starting MySQL............................................ ERROR! The server quit without updating PID file (/usr/local/mysql/data/localhost.localdomain.pid)
解决办法:
1、/usr/local/mysql/data/ 查看并设置此目录权限
2、chmod 755 /etc/rc.d/init.d/mysqld 查看并设置此文件权限
localhost.localdomain.pid 记录进程的进程号,在mysql的配置文件里可以配这个文件的名称
