MySQL 5.7.11编译安装以及修改root密码小结

achiverhai 2016-04-15

系统是CentOS 6.7 64位的,默认MySQL5.7.11下载到/usr/local/src,安装目录在/app/local/mysql目录下,MySQL数据放置目录/app/local/data。MySQL从5.1后采用cmake方式编译安装,所以要先编译安装cmake工具,也可以采用yum方式安装cmake。从MySQL5.7开始编译安装需要boost库的支持,所以也要下载boost库

#wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-5.7.11.tar.gz

#wget https://cmake.org/files/v3.1/cmake-3.1.3.tar.gz

#wget https://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz

如果没有mysql用户则新建mysql用户。

#groupadd mysql

#useradd -g mysql mysql -s /bin/false

创建相应的目录

#mkdir -p /app/local/{mysql,data}

#mkdir  /usr/local/boost

编译安装cmake

#tar zxvf cmake-3.1.3.tar.gz

#cd cmake-3.1.3

#./configure

#make && make install

#cd ../

将boost库解压到/usr/local/boost目录下

#tar zxvf boost_1_59_0.tar.gz

#cd boost_1_59_0/

#mv ./* /usr/local/boost/

#cd ../

编译安装mysql5.7.11

#tar zxvf mysql-5.7.11.tar.gz

#cd mysql-5.7.11

#cmake -DCMAKE_INSTALL_PREFIX=/app/local/mysql/ -DMYSQL_DATADIR=/app/local/data -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DMYSQL_TCP_PORT=3306 -DMYSQL_USER=mysql -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost

#make && make install

#cd ../

#chown -R mysql:mysql /app/local/data/

#chown -R mysql:mysql /app/local/mysql/

#cd /app/local/mysql/bin

#./mysqld --initialize --user=mysql --basedir=/app/local/mysql/ --datadir=/app/local/data/#初始化mysql 并且生成一个随机密码

#mv /etc/my.cnf /etc/my.cnfbak#先备份生成的my.cnf

#cp ../support-files/my-default.cnf /etc/my.cnf

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

#chmod 755 /etc/init.d/mysqld

#chkconfig mysqld on

#service mysqld start

#mysql -uroot -p

Enter password:

用刚才生成的随机密码登录

要是不行,就在my.cnf里配置password

登录后重置root密码

mysql> SET PASSWORD  FOR 'root'@localhost = PASSWORD('123456');

Query OK, 0 rows affected, 1 warning (0.00 sec)

就可以了
