系統是cenos6.7 64位的，默認mysql5.7.11下載到/usr/local/src,安裝目錄在/app/local/mysql目錄下，mysql數據放置目錄/app/local/data。mysql從5.1后采用cmake方式編譯安裝，所以要先編譯安裝cmake工具，也可以采用yum方式安裝cmake。從mysql5.7開始編譯安裝需要boost庫的支持，所以也要下載boost庫
#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
如果沒有mysql用戶則新建mysql用戶。
#groupadd mysql#useradd -g mysql mysql -s /bin/false
創建相應的目錄
#mkdir -p /app/local/{mysql,data}#mkdir /usr/local/boost編譯安裝cmake
#tar zxvf cmake-3.1.3.tar.gz#cd cmake-3.1.3#./configure#make && make install#cd ../
將boost庫解壓到/usr/local/boost目錄下
#tar zxvf boost_1_59_0.tar.gz#cd boost_1_59_0/#mv ./* /usr/local/boost/#cd ../
編譯安裝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 并且生成一個隨機密碼#mv /etc/my.cnf /etc/my.cnfbak#先備份生成的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:
用剛才生成的隨機密碼登錄
要是不行，就在my.cnf里配置password
登錄后重置root密碼
mysql> SET PASSWORD FOR 'root'@localhost = PASSWORD（'123456'）；Query OK, 0 rows affected, 1 warning (0.00 sec)
就可以了
關于小編給大家介紹的MySql5.7.11編譯安裝及修改root密碼的方法就給大家介紹這么多，希望對大家有所幫助！
