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 socket = /home/mysql/mysql/mysql.sock skip-locking key_buffer = 16M max_allowed_packet = 10M table_cache = 64 sort_buffer_size = 512K net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 8M # 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! # #skip-networking # Disable Federated by default #skip-federated # 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 server-id = 1 # 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 #log-bin=mysql-bin # Point the following paths to different dedicated disks #tmpdir = /tmp/ #log-update = /path-to-dedicated-directory/hostname # Uncomment the following if you are using InnoDB tables #innodb_data_home_dir = /home/mysql/mysql/var/ #innodb_data_file_path = ibdata1:10M:autoextend #innodb_log_group_home_dir = /home/mysql/mysql/var/ #innodb_log_arch_dir = /home/mysql/mysql/var/ # You can set .._buffer_pool_size up to 50 – 80 % # of RAM but beware of setting memory usage too high #innodb_buffer_pool_size = 16M #innodb_additional_mem_pool_size = 2M # Set .._log_file_size to 25 % of buffer pool size #innodb_log_file_size = 5M #innodb_log_buffer_size = 8M #innodb_flush_log_at_trx_commit = 1 #innodb_lock_wait_timeout = 50 [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates [isamchk] key_buffer = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [myisamchk] key_buffer = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] wait_timeout=2880000 interactive-timeout=2880000
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
