MySQL5.7源码安装问题汇总

编译安装mysql5.7版本，想试用一下新的版本特性，发现跟之前的5.6版本编译有了一些变化，总结一下避免以后继续入坑。5.6安装方式

cmake版本

5.7编译cmake要求版本最低为2.8，当前为2.6，所以需要升级cmake版本。信息如下

shell> cmake . -DCMAKE_INSTALL_PREFIX=/db/mysql/mysql_57 -DMYSQL_DATADIR=/db/mysql/mysql_57/dataCMake Error at CMakeLists.txt:21 (CMAKE_MINIMUM_REQUIRED):  CMake 2.8.2 or higher is required.  You are running version 2.6.4-- Configuring incomplete, errors occurred!shell> cmake --versioncmake version 2.6-patch 4

cmake官网下载地址

shell> tar zxvf cmake-3.2.2.tar.gzshell> cd cmake-3.2.2/shell> ./bootstrapshell> make && make installshell> cmake --versioncmake version 3.2.2

BOOST库

5.7编译需要boost类库，可使用 -DDOWNLOAD_BOOST=1 -DWITH_BOOST= 参数将在指定路径查找，如未找到会指

定下载并解压到指定的路径

mysql_install_db

之前版本mysql_install_db是在mysql_basedir/script下，5.7放在了mysql_install_db/bin目录下,且已被废弃。

shell> cd /db/mysql/mysql_57shell> bin/mysql_install_db --basedir=. --datadir=data --user=mysql[WARNING] mysql_install_db is deprecated.

初始化密码

mysql5.7会生成一个初始化密码，而在之前的版本首次登陆不需要登录。

shell> cat /root/.mysql_secret # Password set for user 'root@localhost' at 2015-04-22 22:13:23 ?G5W&tz1z.cN修改默认密码shell> bin/mysqladmin -h localhost -u root password '123@qwe' -p'?G5W&tz1z.cN'mysqladmin: [Warning] Using a password on the command line interface can be insecure.Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.

另外mysql5.7的mysql.user表结构被修改

修改mysql.user方式修改密码mysql> update mysql.user set authentication_string=password('123qwe') where user='svoid' and Host = 'localhost';Query OK, 1 row affected (0.01 sec)Rows matched: 1  Changed: 1  Warnings: 0mysql> flush privileges;Query OK, 0 rows affected (0.00 sec)
