MySQL5.7原始碼安裝問題彙總

編譯安裝mysql5.7版本，想試用一下新的版本特性，發現跟之前的5.6版本編譯有了一些變化，總結一下避免以後繼續入坑。5.6安裝方式

cmake版本

5.7編譯cmake要求版本最低為2.8，當前為2.6，所以需要升級cmake版本。資訊如下

shell> cmake . -DCMAKE_INSTALL_PREFIX=/db/mysql/mysql_57 -DMYSQL_DATADIR=/db/mysql/mysql_57/data
CMake 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 --version
cmake version 2.6-patch 4

cmake官網下載地址

shell> tar zxvf cmake-3.2.2.tar.gz
shell> cd cmake-3.2.2/
shell> ./bootstrap
shell> make && make install

shell> cmake --version
cmake version 3.2.2

BOOST庫

5.7編譯需要boost類庫，可使用 -DDOWNLOAD_BOOST=1 -DWITH_BOOST= 引數將在指定路徑查詢，如未找到會指定下載並解壓到指定的路徑

問題描述
shell> cmake . -DCMAKE_INSTALL_PREFIX=/db/mysql/mysql_57 -DMYSQL_DATADIR=/db/mysql/mysql_57/data 

CMake suite maintained and supported by Kitware (kitware.com/cmake).


-- Could not find (the correct version of) boost.
-- MySQL currently requires boost_1_57_0

CMake Error at cmake/boost.cmake:76 (MESSAGE):
  You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=

安裝boost庫
shell> tar jxvf boost_1_57_0.tar.bz2
shell> cd boost_1_57_0/
shell> ./bootstrap.sh
shell> ./b2 install

安裝後目錄
shell> ls /usr/local/include/
boost

shell> cmake . -DCMAKE_INSTALL_PREFIX=/db/mysql/mysql_57 -DMYSQL_DATADIR=/db/mysql/mysql_57/data

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目錄下,且已被廢棄。

shell> cd /db/mysql/mysql_57
shell> bin/mysql_install_db --basedir=. --datadir=data --user=mysql
[WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize

shell> bin/mysqld --initialize
2015-04-21T18:17:53.169216Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

2015-04-21T18:17:59.663795Z 1 [Warning] A temporary password is generated for root@localhost: rq/Oh8VWs1Yh

初始化密碼

mysql5.7會生成一個初始化密碼，而在之前的版本首次登陸不需要登入。

shell> cat /root/.mysql_secret 
# Password set for user 'root@localhost' at 2015-04-22 22:13:23 
?G5W&tz1z.cN

修改預設密碼
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表結構被修改

修改mysql.user方式修改密碼
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: 0

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
