准备工作

1.安装wget、gcc、gcc-c++、bison、ncurses、ncurses-devel

$ yum install –y wget gcc gcc-c++ bison ncurses ncurses-devel

$ cd /usr/local/src/$ wget https://cmake.org/files/v3.7/cmake-3.7.1.tar.gz$ tar zxvf cmake-3.7.1.tar.gz$ cd cmake-3.7.1$ ./bootstrap && gmake && gmake install

$ wget https://nchc.dl.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz$ tar zxf boost_1_59_0.tar.gz$ mv boost_1_59_0 /usr/local/

$ cd /usr/local/src/$ wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.17.tar.gz$ tar zxvf mysql-5.7.17.tar.gz

1.创建用户和组mysql:mysql

$ groupadd mysql$ useradd -r -g mysql -s /sbin/nologin mysql

$ cd /usr/local/src/mysql-5.7.17$ mkdir build$ cd build$ cmake .. \-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \-DSYSCONFDIR=/etc \-DMYSQL_DATADIR=/data/mysql \-DMYSQL_USER=mysql \-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \-DMYSQL_TCP_PORT=3306 \-DWITH_MYISAM_STORAGE_ENGINE=1 \-DWITH_INNOBASE_STORAGE_ENGINE=1 \-DWITH_MEMORY_STORAGE_ENGINE=1 \-DWITH_PARTITION_STORAGE_ENGINE=1 \-DDEFAULT_CHARSET=utf8 \-DDEFAULT_COLLATION=utf8_general_ci \-DEXTRA_CHARSETS=all \-DENABLED_LOCAL_INFILE=1 \-DWITH_BOOST=/usr/local/boost_1_59_0$ make && make install

$ cd /usr/local/mysql$ chown -R mysql:mysql .$ mkdir -p /data/mysql$ chown -R mysql.mysql /data/mysql$ ./bin/mysqld --initialize \--user=mysql \--basedir=/usr/local/mysql \--datadir=/data/mysql$ ./bin/mysql_ssl_rsa_setup --datadir=/data/mysql

4.配置文件

$ cp support-files/my-default.cnf /etc/my.cnf$ vim !$

basedir = /usr/local/mysqldatadir = /data/mysqlport = 3306socket = /tmp/mysql.sock

$ cp support-files/mysql.server /etc/init.d/mysqld$ vim !$

 basedir = /usr/local/mysql  datadir = /data/mysql

6.启动mysqld服务

/etc/init.d/mysqld start

$ chkconfig --add mysqld$ chkconfig mysqld on$ service mysqld start
