linux下非root許可權的mysql安裝

使用mysql使用者安裝mysql

Centos系統:

切換到使用者根目錄:cd ~

下載安裝包:

解壓包:

tar -zxvf mysql-5.1.28-rc.tar.gz

建立安裝目錄:mkdir mysql

cd mysql-5.1.28-rc

./configure –prefix=/home/mysql/mysql  –with-charset=utf8 –with-plugins=innobase

make

make install

新增使用者環境變數:

cd ~

vi .bash_profile

# .bash_profile
 
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=.:/home/mysql/ mysql/bin:$PATH:$HOME/bin
export PATH

使生效:source .bash_profile

修改mysql配置:

cd  ~/mysql

cp /home/mysql/mysql/share/mysql/my-medium.cnf  /home/mysql/mysql/my.cnf

vi 修改my.cnf

# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M – 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /home/mysql/mysql/mysql/var) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the “–help” option.
 
# The following options will be passed to all MySQL clients
 
[client]
#password       = your_password
port           = 3306
socket                = /home/mysql/mysql/mysql.sock
 
# Here follows entries for some specific programs
 
# The MySQL server
[mysqld]
port           = 3306

# Don’t listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the “enable-named-pipe” option) will render mysqld useless!

# Replication Master Server (default)
# binary logging is required for replication
log-bin=mysql-bin
 
# required unique id between 1 and 2^32 – 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master’s port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST=’125.564.12.1′, MASTER_PORT=3306,
#    MASTER_USER=’joe’, MASTER_PASSWORD=’secret’;
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables’ values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 – 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave – required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master – required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master – required
#master-password =   <password>
#
# The port the master is listening on.
# optional – defaults to 3306
#master-port     =  <port>

# binary logging – not required for slaves, but recommended

建立資料庫檔案目錄:mkdir var

初始化資料庫

mysql_install_db –user=mysql –datadir=/home/mysql/mysql/var

啟動:

nohup mysqld_safe  –defaults-file=/home/mysql/mysql/my.cnf &

修改root使用者密碼:

mysqladmin -h ’127.0.0.1′ -u root password 123456

進入mysql

mysql -S  /home/mysql/mysql/mysql.sock

或mysql  -h ’127.0.0.1′ -u root -p

mysql下面建立授權使用者

建立使用者,授權.
Sql程式碼
create user test identified by ’123456′;

grant all privileges on *.* to ‘test’@'localhost’ identified by ’123456′;

flush privileges;

所有主機訪問都可以訪問將localhost換為%
Sql程式碼
刪除使用者,收回許可權
Sql程式碼
delete from mysql.user where user=’test’ and host=’localhost’;

flush privileges;

——————————————
匯入資料命令
./mysql -u root -p -S /home/mysql/mysql/mysql.sock < test.sql

mysql建立使用者並設定為只讀
mysql>GRANT SELECT ON *.* TO ‘mysqlread’@'%’ IDENTIFIED BY ’123456′ WITH GRANT OPTION;
mysql>FLUSH PRIVILEGES;

賦予所有的許可權:

mysql>grant all privileges on *.* to ‘test’@'%’ identified by ’111111′ with grant option;

mysql>FLUSH PRIVILEGES;
備份資料庫:
mysqldump -h localhost -u root -p -S /home/mysql/mysql/mysql.sock dump> ~/dump.sql
