1、创建mysql用户

/usr/sbin/groupadd mysql -g 500

/usr/sbin/useradd -g mysql -u 500 mysql

2、创建目录

mkdir -p /home/tbt/mysqldata

mkdir -p /home/tbt/mysql

chown mysql.mysql -R /home/tbt/mysqldata

chown mysql.mysql -R /home/tbt/mysql

3、安装依赖包

apt-get install libncurses5-dev cmake make gcc g++ -y

4、解压编译

tar zxvf /home/tbt/src/mysql-5.5.38.tar.gz -C /home/tbt/src/

cd /home/tbt/src/mysql-5.5.38

cmake -DCMAKE_INSTALL_PREFIX=/home/tbt/mysql \

-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci \

-DWITH_EXTRA_CHARSETS:STRING=utf8,gbk \

-DWITH_MYISAM_STORAGE_ENGINE=1 \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_MEMORY_STORAGE_ENGINE=1 \

-DWITH_READLINE=1 \

-DENABLED_LOCAL_INFILE=1 \

-DMYSQL_DATADIR=/home/tbt/mysqldata \

-DMYSQL_TCP_PORT=3306 \

make && make install

5、初始化

/home/tbt/mysql/scripts/mysql_install_db --user=mysql --datadir=/home/tbt/mysqldata --basedir=/home/tbt/mysql

6、配置文件及启动脚本

cp /home/tbt/mysql/support-files/my-medium.cnf /home/tbt/mysql/my.cnf

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

sed -i ‘s/conf=\/etc\/my.cnf/conf=\/home\/tbt\/mysql\/my.cnf/‘ /etc/init.d/mysqld

sed -i ‘s/^basedir=/&\/home\/tbt\/mysql/‘ /etc/init.d/mysqld

sed -i ‘s/^datadir=/&\/home\/tbt\/mysqldata/‘ /etc/init.d/mysqld

echo "/etc/init.d/mysqld start" >> /etc/rc.local

/etc/init.d/mysqld start

7、设置root用户密码

/home/tbt/mysql/bin/mysqladmin -uroot password "zhyzhy"

8、修改环境变量

echo "export PATH=$PATH:/home/tbt/mysql/bin" >> /etc/profile.d/mysql.sh

source /etc/profile.d/mysql.sh
