走了一些彎路, 搞定後發一篇自己的教程.
前提, 登陸賬戶爲 root , 如果不是 root 賬戶則在命令前面加 sudo
登陸到 Mysql root 賬戶
使用命令:
mysql -uroot -p
出現 Enter password: , 輸入密碼.
登陸完成出現下列提示:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 249
Server version: 5.5.62-log Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql>
增加授權
GRANT ALL PRIVILEGES ON . TO 'root'@'%'IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;
其中 password 改爲自己要設置的密碼. 執行後要再執行 FLUSH PRIVILEGES; 命令才能使新增的授權生效.
之後使用下面的命令查看所有賬戶, 看到表中有 host 列爲 % , user 列爲 root 即代表設置成功.
use mysql;
select host, user from user;
使用 ctrl + c 退出 mysql
修改 my.cnf 文件
找到並修改 my.cnf 文件, 不清楚的話使用 find / -name my.cnf 搜索, 假如有多個的情況下, 選擇不是 mysql-test 目錄下的那個文件修改.
使用 vim 打開後會看到類似如下內容:
[client]
#password = your_password
port = 3306
socket = /tmp/mysql.sock
[mysqld]
port = 3306
socket = /tmp/mysql.sock
datadir = /usr/local/mysql/var
skip-external-locking
key_buffer_size = 16M
max_allowed_packet = 1M
table_open_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
thread_cache_size = 8
query_cache_size = 8M
tmp_table_size = 16M
bind-address = 0.0.0.0
#skip-networking
max_connections = 500
max_connect_errors = 100
open_files_limit = 65535
...
在 [mysqld] 下加入這行 bind-address = 0.0.0.0 , 已存在但地址不是 0.0.0.0 的話則修改爲 0.0.0.0 , 然後重啓 mysql.
重啓 mysql
/usr/local/mysql/support-files/mysql.server stop
/usr/local/mysql/support-files/mysql.server start
注意有可能你的 mysql.server 文件不在這個目錄下, 那就 find / -name mysql.server 找一下.
