# 切换到mysql安装目录
cd /data/mysql
# 创建日志目录
mkdir logs
# 目录授权mysql用户
chown -R mysql:mysql /data/mysql
# 初始化mysql
bin/mysqld --initialize-insecure --user=mysql --basedir=/data/mysql --datadir=/data/mysql/data
# 拷贝启动文件
cp support-files/mysql.server /etc/init.d/mysqld
# 加执行权限
chmod +x /etc/init.d/mysqld
# 设置环境变量
vim /etc/profile
# 内容如下：
export PATH=$PATH:/data/mysql/bin
# 保存退出，环境变量生效
source /etc/profile
# 启动mysql
/etc/init.d/mysqld start
# 登陆mysql
mysql
# 设置root密码
update mysql.user set authentication_string=password('123qwe') where user='root' and Host = 'localhost';


//添加服务
chkconfig --add mysqld
//显示服务列表
