mysql在centos上的安裝與配置

標籤：mysql

groupadd mysql

useradd -r -g mysql mysql

mv mysql-5.5.27-linux2.6-i686/ /usr/local/

ln -s mysql-5.5.27-linux2.6-i686/ mysql

cd /usr/local/mysql

chown -R mysql .

chgrp -R mysql .

/usr/local/mysql/scripts/mysql_install_db --user=mysql

ERROR:

scripts/mysql_install_db: ./bin/my_print_defaults: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

Neither host ‘host-1‘ nor ‘localhost‘ could be looked up with

./bin/resolveip

Please configure the ‘hostname‘ command to return a correct

hostname.

If you want to solve this at a later stage, restart this script

with the --force option

yum install glibc.i686

yum install zlib.i686

yum install libgcc.i686

#與mysql的版本對應，下載libaio-0.3.107-10.el6.i686.rpm安裝

rpm -ivh libaio-0.3.107-10.el6.i686.rpm 

chown -R root:root ./

chown -R mysql:mysql data

cp support-files/mysql.server /etc/init.d/mysql

service mysql start

ps -ef|grep mysql 

#修改mysql的root使用者密碼，root初始密碼為空白的：

執行命令：./bin/mysqladmin -u root password ‘密碼‘

# ‘Can‘t connect to local MySQL server through socket ‘/tmp/mysql.sock‘

# find / -name mysql.sock

# /var/lib/mysql/mysql.sock，執行以下命令後再重設密碼Ok，

ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

Error：

# ./bin/mysql -uroot -p

./bin/mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

安裝兩個包後解決：

yum install libstdc++.so.6 

yum install libncurses.so.5

授權root遠程登入

mysql>GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ WITH GRANT OPTION

mysql>FLUSH PRIVILEGES

#Mysql初始化root密碼和允許遠端存取

mysql預設root使用者沒有密碼，輸入mysql –u root 進入mysql

1、初始化root密碼

進入mysql資料庫

mysql>update user set password=PASSWORD(‘123456’) where User=‘root‘;

2、允許mysql遠端存取,可以使用以下三種方式:

a、改表。

mysql -u root –p

mysql>use mysql;

mysql>update user set host = ‘%‘ where user = ‘root‘;

mysql>select host, user from user;

b、授權。

例如，你想root使用123456從任何主機串連到mysql伺服器。

mysql>GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘123456‘ WITH GRANT OPTION;

如果你想允許使用者jack從ip為10.10.50.127的主機串連到mysql伺服器，並使用654321作為密碼

mysql>GRANT ALL PRIVILEGES ON *.* TO ‘jack‘@’10.10.50.127’ IDENTIFIED BY ‘654321‘ WITH GRANT OPTION;

mysql>FLUSH RIVILEGES

c:在安裝mysql的機器上運行：

//進入MySQL伺服器

d:\mysql\bin\>mysql -h localhost -u root

//賦予任何主機訪問資料的許可權

mysql>GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ WITH GRANT OPTION

//使修改生效

mysql>FLUSH PRIVILEGES

//退出MySQL伺服器

mysql>EXIT
