centos 上编译安装 MySQL-优快云博客

一、移除CentOS自带的mysql

yum remove mysql mysql-server compat-mysql51
rpm -e --nodeps mysql-libs-5.1.*

二、安装编译依赖包

yum -y install cmake
yum -y install bison

三、下载MySQL

wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.26.tar.gz

四、编译安装MySQL

/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.6.26.tar.gz
cd mysql-5.6.26
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DWITH_EXTRA_CHARSETS=complex -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DENABLED_LOCAL_INFILE=1 -DENABLED_PROFILING=on -DWITH_SSL=bundled -DWITH_ZLIB=bundled -DENABLED_THREAD_SAFE_CLIENT=on  -DWITH_EMBEDDED_SERVER=on   
make && make install
cd ../

五、以mysql用户帐号的身份建立数据表

/usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
mkdir -p /usr/local/webserver/
rm -f /usr/local/webserver/mysql
ln -s /usr/local/mysql/ /usr/local/webserver/mysql
rm -f /usr/local/mysql/my.cnf
chmod +w /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql

六、创建my.cnf配置文件
1、

rm -f /etc/my.cnf
vi /etc/my.cnf

2、输入以下内容

[client]
#character-set-server = utf8
port    = 3306
socket  = /tmp/mysql.sock

[mysqld]
character-set-server = utf8
replicate-ignore-db = mysql
replicate-ignore-db = test
replicate-ignore-db = information_schema
user    = mysql

[mysqldump]
quick
max_allowed_packet = 32M

3、启动MySQL

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
service mysql start

4、通过命令行登录管理MySQL服务器（提示输入密码时直接回车）

/usr/local/webserver/mysql/bin/mysql -uroot -p

5、输入以下SQL语句，设置root用户的密码

mysql> use mysql;
mysql> update user set Password = password('123456') where User='root'; 
mysql> flush privileges;
mysql> exit;

6、设置开机启动MySQL

chkconfig --add mysql
chkconfig mysql on
