CentOS 5.5 下安装 Mysql 5.5

 

MySQL 5.5 使用InnoDB作为默认的数据库存储引擎

下载： http://www.mysql.com/downloads/

1.    建 mysql用户

groupadd mysql useradd -g mysql -s /bin/false -M mysql

2.    mysql 5.5需要用 cmake来编译：
安装cmake,及相关包：

yum install  -y \ cmake.x86_64 \ gcc \ gcc-c++  \ ncurses-devel.x86_64 \ bison.x86_64 \ libaio.x86_64

3.     解压 mysql5.5.tar.gz ,编译:

cmake \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_DATADIR=/data/mysqldata \ -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_MYISAM_STORAGE_ENGINE=1 \ -DENABLED_LOCAL_INFILE=1 \ -DMYSQL_TCP_PORT=3306 \ -DEXTRA_CHARSETS=all \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DMYSQL_USER=mysql \ -DWITH_DEBUG=0

然后执行：

Make && make install

如果想重新 make,需清除cmake用：

make clean rm -f CMakeCache.txt

4.    设置：

cp support-files/my-medium.cnf /etc/my.cnf cp support-files/mysql.server /usr/local/mysql/bin/ chmod 755 /usr/local/mysql/bin/mysql.server chown -R mysql .root  /usr/local/mysql cd /usr/local/mysql mkdir /data/mysqldata scripts/mysql_install_db --user=mysql cp –rpf /usr/local/mysql/data/* /data/mysqldata

5.     添加相对路径：

echo "  export PATH=$PATH:/usr/local/mysql/bin"  >> /etc/profile source /etc/profile

6.    启动和停止 Mysql：

mysql.server   start mysql.server   stop

7.    查看是否有 3306端口：

netstat -anp | grep LISTEN

8.    编辑 /etc/my.cnf，添加红色字体:

[client] default-character-set=utf8 [mysqld] default-character-set=utf8 log-bin=mysql-bin expire_logs_days = 5

9.    进入 Mysql 

mysql 查看 mysql状态,字符集最好都是utf8 mysql> status; -------------- mysql Ver 14.14 Distrib 5.5.21, for Linux (x86_64) using EditLine wrapper Connection id:           2 Current database: Current user:            root@localhost SSL:                     Not in use Current pager:           stdout Using outfile:           '' Using delimiter:         ; Server version:          5.5.21-log Source distribution Protocol version:        10 Connection:              Localhost via UNIX socket Server characterset:    utf8 Db     characterset:    utf8 Client characterset:    utf8 Conn. characterset:    utf8 UNIX socket:             /usr/local/mysql/mysql.sock Uptime:                  26 min 45 sec
