在我百撕不得其姐情况下,百度到了一篇亲测有用的文章,如下:
1.这里我将Mysql安装在/usr/local/mysql目录里面，也可以安装在其他地方;
mkdir /usr/local/mysql
2.下载MySQL压缩包
wget http://dev.MySQL.com/get/Downloads/MySQL-5.7/mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz
// 由于MySQL运行需要libaio库，所以需要运行以下命令进行安装
yum install -y libaio // 如果上边的命令不行的话 可以使用下边的命令 curl -O -L http://dev.MySQL.com/get/Downloads/MySQL-5.7/mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz
3.解压并复制
tar -xvf mysql-5.7.11-Linux-glibc2.5-x86_64.tar.gz mv mysql-5.7.11-linux-glibc2.5-x86_64/* /usr/local/mysql/
4.创建data目录
mkdir /usr/local/mysql/data
5.创建mysql用户组及其用户
groupadd mysql
useradd -r -g mysql mysql
6.初始化数据
切换到mysql文件夹下面
[root@localhost mysql] ./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ 2016-01-20 02:47:35 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize 2016-01-20 02:47:45 [WARNING] The bootstrap log isn't empty: 2016-01-20 02:47:45 [WARNING] 2016-01-19T18:47:36.732678Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead 2016-01-19T18:47:36.750527Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000) 2016-01-19T18:47:36.750560Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000
7.复制配置文件到 /etc/my.cnf
cp -a ./support-files/my-default.cnf /etc/my.cnf (选择y)
8.MySQL的服务脚本放到系统服务中
cp -a ./support-files/mysql.server /etc/init.d/mysqld vim编辑etc文件夹下的my.cnf文件 # These are commonly set, remove the # and set as required. basedir = /usr/local/mysql datadir = /usr/local/mysql/data port = 3306 # server_id = ..... socket = /tmp/mysql.sock character-set-server = utf8 # 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. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M
9.创建In
ln -s /usr/local/mysql/bin/mysql /usr/bin/
10.启动服务
service mysqld start
11.初始化密码
mysql5.7会生成一个初始化密码，在root中.mysql_secret文件中。 [root@localhost ~]# cat /root/.mysql_secret # Password set for user 'root@localhost' at 2017-03-16 00:52:34 ws;fmT7yh0CM
12.登录并修改密码
[root@localhost ~]# mysql -u root -p alter user root@localhost identified by 'root'; flush privileges;
13.退出重新登录，完成
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| sys |
+--------------------+
4 rows in set (0.11 sec)
ok了
创建数据库：
create database abc;
导入sql文件：
source /xxx/xxx/xxxx.sql;
ok!
