mysql 5.5.23的安装及配置

myql 5.5.23安装：

1. 安装一些需要的库

yum install gcc-c++　 gperf　 ncurses-devel　 readline-devel　 libaio-devel bison ncurses-devel

2. mysql 5.5以后用cmake编译了，安装cmake:

wget http://www.cmake.org/files/v2.8/cmake-2.8.8.tar.gz
cd cmake-2.8.8

./configure

make && make install



3.编译mysql:

下载解压后：

cd mysql-5.5.23

cmake -DCMAKE_INSTALL_PREFIX=/data1/app/services/mysql5_5 -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DWITH_SSL=system -DWITH_ZLIB=system -DENABLED_LOCAL_INFILE=1 -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DMYSQL_TCP_PORT=3306 -DMYSQL_USER=mysql

make && make install

cd /data1/app/services/mysql5_5
scripts/mysql_install_db --user=mysql --datadir=data
cp support-files/mysql.server /etc/init.d/mysql55
chmod 755 /etc/init.d/mysql55
chkconfig --level 345 mysql55 on

启动：

service mysql start

修改密码：

mysql -h 127.0.0.1

GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY 'password' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO root@"127.0.0.1" IDENTIFIED BY 'password' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO root@"localhost" IDENTIFIED BY 'password' WITH GRANT OPTION;
flush privileges;
