编译安装mysql 5.1使用utf8解决乱码问题

1. yum install –y gcc  gcc-c++  ncurses-devel  bison
2. wget http://mirrors.ircam.fr/pub/mysql/Downloads/MySQL-5.1/mysql-5.1.55.tar.gz
3.
shell> groupadd mysql
shell> useradd -g mysql mysql
shell> gunzip < mysql-5.1.55.tar.gz | tar -xvf -
shell> cd mysql-5.1.55
shell> ./configure   --prefix=/usr/local/mysql   --with-charset=utf8   --with-extra-charsets=all  --with-collation=utf8_general_ci   --enable-assembler \
--enable-thread-safe-client   --with-big-tables  --with-readline   --with-plugins=innodb_plugin
shell> make –j 4  #编译使用cpu数目,编译更快
shell> make install
shell> cp support-files/my-medium.cnf /etc/my.cnf
shell> cd /usr/local/mysql
shell> bin/mysql_install_db   --user=mysql
shell> chown -R root  .
shell> chown -R mysql var
shell> chgrp -R mysql .
shell> bin/mysqld_safe   --user=mysql &
 
4.这样装完以后竟然还是 +--------------------------+----------------------------------------+
| Variable_name            | Value                                  |
+--------------------------+----------------------------------------+
| auto_increment_offset    | 1                                      |
| character_set_client     | latin1                                 |
| character_set_connection | latin1                                 |
| character_set_database   | utf8                                   |
| character_set_filesystem | binary                                 |
| character_set_results    | latin1                                 |
| character_set_server     | utf8                                   |
| character_set_system     | utf8                                   |
| character_sets_dir       | /usr/local/mysql/share/mysql/charsets/ |
+--------------------------+----------------------------------------+ 最后在my.cnf中设置 [mysqld]和[client] 中设置:default-character-set=utf8. 但是php中还是中还是乱码,为了不改程序.终于找到方法了原文地址--[mysqld]加入 default-character-set=utf8
init_connect='SET collation_connection = utf8_general_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_general_ci
skip-character-set-client-handshake
完美解决!!
