折腾：
【已解决】Mac本地搭建mysql数据库并导入已备份出的sql文件
期间，先要去Mac本地中，去安装和阿里云RDS上版本一样的5.7的mysql数据库。
mac install mysql 5.7
在MAC OSX 10.11 上安装 MySQL 5.7 – 简书

安装后，新开终端果然找不到：
<code>Last login: Thu Apr 26 09:12:23 on ttys008 ➜ ~ which mysql mysql not found </code>
所以去加到环境变量中
<code>➜ ~ ll /usr/local/mysql/bin/mysql* -rwxr-xr-x 1 root wheel 4.9M 3 4 23:25 /usr/local/mysql/bin/mysql -rwxr-xr-x 1 root wheel 26M 3 4 23:25 /usr/local/mysql/bin/mysql_client_test_embedded -rwxr-xr-x 1 root wheel 4.7K 3 4 22:27 /usr/local/mysql/bin/mysql_config -rwxr-xr-x 1 root wheel 4.3M 3 4 23:25 /usr/local/mysql/bin/mysql_config_editor -rwxr-xr-x 1 root wheel 26M 3 4 23:25 /usr/local/mysql/bin/mysql_embedded -rwxr-xr-x 1 root wheel 5.8M 3 4 23:25 /usr/local/mysql/bin/mysql_install_db -rwxr-xr-x 1 root wheel 3.6M 3 4 23:25 /usr/local/mysql/bin/mysql_plugin -rwxr-xr-x 1 root wheel 4.5M 3 4 23:25 /usr/local/mysql/bin/mysql_secure_installation -rwxr-xr-x 1 root wheel 3.7M 3 4 23:25 /usr/local/mysql/bin/mysql_ssl_rsa_setup -rwxr-xr-x 1 root wheel 3.6M 3 4 23:25 /usr/local/mysql/bin/mysql_tzinfo_to_sql -rwxr-xr-x 1 root wheel 5.3M 3 4 23:25 /usr/local/mysql/bin/mysql_upgrade -rwxr-xr-x 1 root wheel 4.5M 3 4 23:25 /usr/local/mysql/bin/mysqladmin -rwxr-xr-x 1 root wheel 5.0M 3 4 23:25 /usr/local/mysql/bin/mysqlbinlog -rwxr-xr-x 1 root wheel 4.6M 3 4 23:25 /usr/local/mysql/bin/mysqlcheck -rwxr-xr-x 1 root wheel 28M 3 4 23:25 /usr/local/mysql/bin/mysqld -rwxr-xr-x 1 root wheel 60M 3 4 23:25 /usr/local/mysql/bin/mysqld-debug -rwxr-xr-x 1 root wheel 26K 3 4 22:27 /usr/local/mysql/bin/mysqld_multi -rwxr-xr-x 1 root wheel 28K 3 4 22:27 /usr/local/mysql/bin/mysqld_safe -rwxr-xr-x 1 root wheel 4.6M 3 4 23:25 /usr/local/mysql/bin/mysqldump -rwxr-xr-x 1 root wheel 7.3K 3 4 22:27 /usr/local/mysql/bin/mysqldumpslow -rwxr-xr-x 1 root wheel 4.5M 3 4 23:25 /usr/local/mysql/bin/mysqlimport -rwxr-xr-x 1 root wheel 5.5M 3 4 23:25 /usr/local/mysql/bin/mysqlpump -rwxr-xr-x 1 root wheel 4.5M 3 4 23:25 /usr/local/mysql/bin/mysqlshow -rwxr-xr-x 1 root wheel 4.6M 3 4 23:25 /usr/local/mysql/bin/mysqlslap -rwxr-xr-x 1 root wheel 26M 3 4 23:25 /usr/local/mysql/bin/mysqltest_embedded -rwxr-xr-x 1 root wheel 7.2M 3 4 23:25 /usr/local/mysql/bin/mysqlxtest ➜ ~ vi ~/.bashrc ➜ ~ cat ~/.bashrc export NVM_DIR="/Users/crifan/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && .

加好了。
<code>➜ ~ sudo /usr/local/mysql/support-files/mysql.server stop Password: Sorry, try again. Password: ERROR! MySQL server PID file could not be found! </code>
注意：此处密码是sudo的密码。不是那个临时密码。
但是貌似此处并没有开启mysql的server
所以估计才提示找不到pid
<code>➜ ~ mysqld_safe --skip-grant-tables /usr/local/mysql/bin/mysqld_safe: line 647: /usr/local/mysql/data/promote.cache-dns.local.err: Permission denied Logging to '/usr/local/mysql/data/promote.cache-dns.local.err'. 2018-04-26T03:39:13.6NZ mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data /usr/local/mysql/bin/mysqld_safe: line 144: /usr/local/mysql/data/promote.cache-dns.local.err: Permission denied /usr/local/mysql/bin/mysqld_safe: line 198: /usr/local/mysql/data/promote.cache-dns.local.err: Permission denied /usr/local/mysql/bin/mysqld_safe: line 906: /usr/local/mysql/data/promote.cache-dns.local.err: Permission denied rm: /usr/local/mysql/data/promote.cache-dns.local.pid.shutdown: Permission denied 2018-04-26T03:39:13.6NZ mysqld_safe mysqld from pid file /usr/local/mysql/data/promote.cache-dns.local.pid ended /usr/local/mysql/bin/mysqld_safe: line 144: /usr/local/mysql/data/promote.cache-dns.local.err: Permission denied ➜ ~ sudo mysqld_safe --skip-grant-tables Logging to '/usr/local/mysql/data/promote.cache-dns.local.err'. 2018-04-26T03:39:20.6NZ mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data </code>
再去开另外一个终端：
<code>
Last login: Thu Apr 26 11:33:48 on ttys009
➜ ~ sudo mysql -u root
Password:

</code>
然后再去：
关掉之前的–skip-grant-tables的窗口：
用Control+Z去关掉：
<code>➜ ~ sudo mysqld_safe --skip-grant-tables Logging to '/usr/local/mysql/data/promote.cache-dns.local.err'. 2018-04-26T03:39:20.6NZ mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data ^C^C^C^C^C^Z [1] + 21662 suspended sudo mysqld_safe --skip-grant-tables </code>
去试试mysql的正常登录：
结果竟然不用密码直接登录了：
<code>➜ ~ mysql -u root Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 Server version: 5.7.22 MySQL Community Server (GPL) Copyright (c) 2000, 2018, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql> [2] + 22192 suspended mysql -u root </code>
去看看进程：
<code>➜ ~ ps -ef | grep mysql_safe 501 22210 20742 0 11:43上午 ttys009 0:00.00 grep --color=auto --exclude-dir=.bzr --exclude-dir=CVS --exclude-dir=.git --exclude-dir=.hg --exclude-dir=.svn mysql_safe ➜ ~ </code>
好像没有了那个mysql_safe了啊。
又开了终端，发现还是无需密码就可以登录mysql
去取消这个不带密码的限制
好像刚才少了：
flush privileges;
去加上：
<code>➜ ~ mysql -u root
Welcome to the MySQL monitor. Commands end with ; or \g.

</code>然后继续找找
然后flush后，就生效了：
就需要密码登录了：
<code> ~ mysql -u root ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO) ➜ ~ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

Type '\c' to clear the current input statement. mysql> </code>
然后就可以正常操作了。
然后找到之前的mysql的工具，比如navicat或Sequel Pro
去连接本地mysql看看
结果连接出错：
【已解决】Mac中Sequel连接本地Mysql出错：Unable to connect to host 127.0.0.1, or the request timed out
【总结】
此处在Mac本地中，安装并正常访问mysql的过程是：
1.先去mysql官网下载dmg安装文件，然后安装：
MySQL :: Download MySQL Community Server
-》
MySQL :: Download MySQL Community Server
找到此处需要的：
341.1M的(mysql-5.7.22-macos10.13-x86_64.dmg)
macOS 10.13 (x86, 64-bit), DMG Archive
下载后，双击dmg即可安装。
注意期间会有生成一个临时密码。
2.把mysql加到PATH环境变量中
<code>vi ~/.bashrc </code>
把：
<code>/usr/local/mysql/bin </code>
加进去：
<code>export PATH="/usr/local/mysql/bin:/Users/crifan/Library/Python/2.7/bin:/Users/crifan/Library/Python/3.6/bin:$PATH" </code>
然后source一下使得当前就生效：
<code>source ~/.bashrc </code>
通过：
<code>➜ ~ which mysql /usr/local/mysql/bin/mysql </code>
确认已把mysql加到环境变量中了。
3.Mac中dmg安装的mysql默认不需要密码就可以登录的
所以此处最好去设置对应的密码
且如果用默认的临时密码，可能会导致其他工具无法正常连接
单独开个终端shell去：
<code>sudo mysqld_safe --skip-grant-tables </code>
然后另外再开个终端去：
<code>use mysql;
update user set authentication_string=password('new_password') where user='root’;
flush privileges;
exit
</code>注意：
<code>password('new_password
</code>中，是英文的单引号’，不是中文的单引号‘
-》我就是从别人网页中拷贝过来，结果发现是单引号，导致无法继续正常执行的。
然后就可以正常使用：
<code>mysql -u root </code>
去用新密码登录进去了。
4.为了防止其他mysql工具连接出错，还需要设置密码不过期，且重新再去设置一下新密码
<code>mysql -u root -p
SET PASSWORD = PASSWORD('your_new_password’);
use mysql;
update user set password_expired='N' where user='root’;
flush privileges;
exit
</code>即可。
5.后续记得用mysql之前，确保mysql（的server）是正常运行了的：
对于mysql的服务的管理是：
<code>sudo /usr/local/mysql/support-files/mysql.server status sudo /usr/local/mysql/support-files/mysql.server start sudo /usr/local/mysql/support-files/mysql.server stop sudo /usr/local/mysql/support-files/mysql.server restart </code>
