cd?mysql-5.5.56

2.4.2 ?編譯安裝

cmake?.?-DCMAKE_INSTALL_PREFIX=/app/mysql-5.5.56?-DMYSQL_DATADIR=/app/mysql-5.5.56/data?-DMYSQL_UNIX_ADDR=/app/mysql-5.5.56/tmp/mysql.sock?-DDEFAULT_CHARSET=utf8?-DDEFAULT_COLLATION=utf8_general_ci?-DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii?-DENABLED_LOCAL_INFILE=ON?-DWITH_INNOBASE_STORAGE_ENGINE=1?-DWITH_FEDERATED_STORAGE_ENGINE=1?-DWITH_BLACKHOLE_STORAGE_ENGINE=1?-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1?-DWITHOUT_PARTITION_STORAGE_ENGINE=1?-DWITH_FAST_MUTEXES=1?-DWITH_ZLIB=bundled?-DENABLED_LOCAL_INFILE=1?-DWITH_READLINE=1?-DWITH_EMBEDDED_SERVER=1?-DWITH_DEBUG=0

make?&&?make?install

2.4.3 創建tmp目錄及配置文件

mkdir?/app/mysql-5.5.56/tmp

cd?/app/mysql-5.5.56

cp?support-files/my-small.cnf?/etc/my.cnf

chown?-R?mysql.mysql?/app/mysql-5.5.56

chmod?-R?1777?/app/mysql-5.5.56/tmp

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

chmod?+x?/etc/init.d/mysqld

ln?-s?/app/mysql-5.5.56?/app/mysql

cp?/app/mysql-5.5.56/bin/*?/usr/local/sbin/

chkconfig?--add?mysqld

chkconfig?mysqld?on

2.4.6 配置UTF-8字符集

sed?-i?'22a?default-character-set=utf8'?/etc/my.cnf

sed?-i?'38a?character-set-server=utf8'?/etc/my.cnf

sed?-i?'83a?default-character-set=utf8'?/etc/my.cnf

查看字符集：

mysql>?show?variables?like?'character%';
