Mac安装和卸载Mysql5.7.11的方法
系统是cenos6.764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
#wgethttp://mirrors.sohu.com/mysql/MySQL-5.7/mysql-5.7.11.tar.gz #wgethttps://cmake.org/files/v3.1/cmake-3.1.3.tar.gz #wgethttps://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。
#groupaddmysql #useradd-gmysqlmysql-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
#tarzxvfcmake-3.1.3.tar.gz #cdcmake-3.1.3 #./configure #make&&makeinstall #cd../
将boost库解压到/usr/local/boost目录下
#tarzxvfboost_1_59_0.tar.gz #cdboost_1_59_0/ #mv./*/usr/local/boost/ #cd../
编译安装mysql5.7.11
#tarzxvfmysql-5.7.11.tar.gz #cdmysql-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&&makeinstall #cd../ #chown-Rmysql:mysql/app/local/data/ #chown-Rmysql: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 #chmod755/etc/init.d/mysqld #chkconfigmysqldon #servicemysqldstart #mysql-uroot-p
Enterpassword:
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>SETPASSWORDFOR'root'@localhost=PASSWORD（'123456'）； QueryOK,0rowsaffected,1warning(0.00sec)
就可以了
