wget ftp://ftp.ntu.edu.tw/pub/MySQL/Downloads/MySQL-5.5/mysql-5.5.27.tar.gz
 
# 创建用户和组
groupadd mysql
useradd -g mysql  -s /usr/sbin/nologin  mysql
 
# 创建安装目录
mkdir  /usr/local/mysql
 
# 创建数据库目录
mkdir  /usr/local/mysql/data
 
# 解压
tar -zxvf mysql-5.5.17.tar.gz
cd mysql-5.5.17
 
# 编译及安装mysql
# cmake编译：
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_unicode_ci \
-DWITH_READLINE=1 \
-DWITH_SSL=system \
-DWITH_EMBEDDED_SERVER=1 \
-DENABLED_LOCAL_INFILE=1 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_DEBUG=0    \
-DWITH_SSH=bundled
 
# 安装mysql
make && make install
 
# 复制配置文件
cp support-files/my-medium.cnf  /etc/my.cnf
 
# 设置权限
chmod +x /usr/local/mysql
chown -R mysql.mysql /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql/data
 
# 配置开机自启动
cp support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig mysqld on
 
# 修改my.cnf配置
vim /etc/my.cnf
# [mysqld] 添加：
datadir=/usr/local/mysql/data
default-storage-engine=MyISAM
 
# 以下可选：
log-error =/usr/local/mysql/data/error.log
pid-file = /usr/local/mysql/data/mysql.pid
user = mysql
tmpdir = /tmp
 
# 初始化数据库
/usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data &
 
# 启动MySQL
/usr/local/mysql/bin/mysqld_safe –defaults-file=/etc/my.cnf &
或者：
/etc/init.d/mysql start （service mysql start）
 
# 测试MySQL是否启动
# 1）查看是否有进程mysql
ps -ef | grep mysql
# 2）查看端口是否运行
netstat -tnl | grep 3306
# 3）读取mysql版本信息
/usr/local/mysql/bin/mysqladmin version
 
# 至此，MySQL安装完成
