mysql的安裝和基本配置

標籤：mysql

一、mysql的安裝和基本配置

1 安裝cmake
#./configure
#make &&make install

2 安裝mysql
# yum install ncurses* bison*
  # cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/database/mydata -DSYSCONFDIR=/etc -DTMPDIR=/tmp -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DENABLED_LOCAL_INFILE=1 -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DWITH_EXTRA_CHARSETS=all
  # make
  # make install

3 mysql基本配置 

# vim /etc/my.cnf
[client]
user = mysql
port = 3306
socket = /tmp/mysql.sock

[mysqld]
innodb_buffer_pool_size = 128M
log_bin = master-log
basedir = /usr/local/mysql
datadir = /database/mydata
port = 3306
server_id = 1
socket = /tmp/mysql.sock
join_buffer_size = 128M
sort_buffer_size = 2M
read_rnd_buffer_size = 2M

character_set_server = utf8

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

# cd /usr/local/mysql
  # ./scripts/mysql_install_db --user=mysql --datadir=/database/mydata --explicit_defaults_for_timestamp=1
  # service mysqld start
 
4 串連到資料庫
# mysql -S /tmp/mysql.sock  \\使用socket串連到mysql
# mysql -u root -h localhost

資料庫檔案預設在：cd /usr/share/mysql
設定檔預設在：/etc/my.cnf
———————————–
資料庫目錄：/var/lib/mysql/
設定檔：/usr/share/mysql(mysql.server命令及設定檔)
相關命令：/usr/bin(mysqladmin、mysqldump等命令)(*mysql的一種安全啟動方式：/usr/bin/mysqld_safe –user=root &)
啟動指令碼：/etc/rc.d/init.d/
首先你可以使用以下的命令來尋找MySQL
[[email protected] /]# find / -name “mysql” -print
一般來說mysql是放在/usr/local/mysql/下的。
然後在其bin目錄下有個mysql_config檔案，vi之，你會看見這麼一句：
ldata=’/usr/local/mysql/var’

忘記root密碼
service mysqld stop
mysqld_safe --user=root --skip-grant-tables
mysql -u root
use mysql
update user set password=password("666666") where user="root";
flush privileges;
