1.useradd -s /sbin/nologin -M mysql #新增mysql运行用户
2.yum -y install ncurses-devel libaio-devel cmake gcc-c++ #安装依赖包
3.编译，注：重新cmake需要删除CMakeCache.txt文件
cmake -DCMAKE_INSTALL_PREFIX=/zhonghong/mysql \
-DMYSQL_DATADIR=/zhonghong/mysql/data \
-DSYSCONFDIR=/etc \
-DMYSQL_USER=mysql \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_READLINE=1 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
4.安装
make -j4 && make install
5.修改配置文件
cp support-files/my-default.cnf /etc/my.cnf
vim /etc/my.cnf
[mysqld]
basedir=/zhonghong/mysql
datadir=/zhoghong/mysql/data
port=3306
user=mysql
socket=/tmp/mysql.sock
character-set-server=utf8
log-error=/var/log/mysqld.log
pid-file=/tmp/mysqld.pid
[mysql]
socket=/zhonghong/mysql/mysql.sock
[client]
socket=/zhonghong/mysql/mysql.sock
6. 初始化安装数据库
/zhonghong/mysql/scripts/mysql_install_db --basedir=/zhonghong/mysql/ --datadir=/zhonghong/mysql/data --user=mysql
7.更改mysql目录的属主和组为mysql
chown -R mysql.mysql /zhonghong/msyql
8.设置开启自动，并设置环境变量
cp /zhonghong/mysql/support-files/mysql.server /etc/init.d/mysqld
chkconfig mysqld on
echo ‘PATH=/zhonghong/mysql/bin/:$PATH‘ >>/etc/profile
8.为root设置密码和删除test默认数据库
mysqladmin -u root -p password ‘newpassword‘
drop database test;
