CentOS6.8安装编译mysql5.6

1. 安装gcc

yuminstallgccgcc-c++ncurses-develperl

2. 下载源码包（一定要是source类型的，要不然从cmake就会出错）

3. 解压后进入mysql目录

4.cmake编译配置（会出错误）

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DENABLED_LOCAL_INFILE=ON \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DCOMPILATION_COMMENT='JSS for mysqltest' \
-DWITH_READLINE=ON \
-DSYSCONFDIR=/data/mysqldata/3306 \
-DMYSQL_UNIX_ADDR=/data/mysqldata/3306/mysql.sock

5.出错

-- Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)
CMake Error at cmake/readline.cmake:85 (MESSAGE):

remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu,package name is libncurses5-dev,on RedHat and derivates it is ncurses-devel.

6.解决错误需要安装缺失包

yum install ncurses-devel

7.重新删除配置文件：
rm -rf CMakeCache.txt

8. 重新执行第4步

9. make && make install(如果出错，可能是因为没有权限，要分开用sudo执行)

*****************************************

启动mysql

1. cpsupport-files/mysql.server/etc/init.d/mysqld
3. vim/etc/profile
5. PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
7. exportPATH
9. source/etc/profile

还要对log，pid，data等目录做chown设置

(上面的配置可以让mysql通过service mysqld start启动)

首次登录，修改root密码

mysqld --skip-grant-tables，这个命令会出现警告之类的，不用管，在新窗口中登录mysql

执行命令：update mysql.user set password=PASSWORD('root') where User='root';

刷新执行: mysql> flush privileges;

1. 使用具有所有权限的用户登录 2. 创建用户：mysql> insert into mysql.user(Host,User,Password) values("localhost","demo",password("demo")); flush privileges; 3. 退出，用demo用户登录mysql 4. 成功登录后退出 5. 为用户授权：grant 权限 on 数据库.* to 用户名@登录主机 identified by "密码"; （grant all privileges on *.* to demo@localhost identified by 'demo'; ） 6. 刷新系统权限表：mysql>flush privileges;
