centos7上编译安装mysql5.6

 注意，在做实验室统一关闭防火墙做的，在生产环境需要做防火墙规则的，大家要注意，做的时候尽量都是模仿生产环境的，比如服务一般都在/data/soft下面，尽量避免在/usr/local/下面。

安装编译mysql所需要的软件

[root@localhost soft]# yum -y install gcc gcc-c++ ncurses-devel perl
[root@localhost soft]# wget https://cmake.org/files/v3.11/cmake-3.11.1.tar.gz
[root@localhost soft]# tar -xvf cmake-3.11.1.tar.gz
[root@localhost soft]# cd cmake-3.11.1/
[root@localhost cmake-3.11.1]# ./bootstrap && make && make install　

创建mysql用户，安装目录和数据目录

[root@localhost soft]# groupadd mysql
[root@localhost soft]# useradd -r -g mysql mysql
[root@localhost soft]# mkdir /data/soft/mysql
[root@localhost soft]# mkdir /data/mysqldb　

下载mysql5.6的源码,注意有些版本下过来编译会出现不兼容的情况，需要选择cmake能够兼容的mysql版本。

[root@localhost soft]# wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.16.tar.gz 
[root@localhost soft]# tar -xvf mysql-5.6.16.tar.gz
[root@localhost soft]# cd mysql-5.6.16/　

编译安装

[root@localhost mysql-5.6.16]# cmake -DCMAKE_INSTALL_PREFIX=/data/soft/mysql -DMYSQL_UNIX_ADDR=/data/soft/mysql/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DMYSQL_DATADIR=/data/mysqldb -DMYSQL_TCP_PORT=3306 -DENABLE_DOWNLOADS=1
[root@localhost mysql-5.6.16]# rm -rf CMakeCache.txt
[root@localhost mysql-5.6.16]# make && make install　

修改mysql目录所有者和组

[root@localhost soft]# chown -R mysql:mysql /data/mysqldb/
[root@localhost soft]# chown -R mysql:mysql /data/soft/mysql/　

初始化数据目录

[root@localhost mysql-5.6.16]# cd /data/soft/mysql
[root@localhost mysql]# scripts/mysql_install_db --user=mysql --datadir=/data/mysqldb　

注意：此处出现问题了

# scripts/mysql_install_db --user=mysql --datadir=/data/mysqldb　
Can't locate Data/Dumper.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at scripts/mysql_install_db line 42.
BEGIN failed--compilation aborted at scripts/mysql_install_db line 42.

解决办法为

yum -y install 'perl(Data::Dumper)' 

修改mysql配置文件

[root@localhost mysql]# cp /data/soft/mysql/support-files/my-default.cnf  /etc/my.cnf
[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysqld

文件修改如下

[root@localhost mysql]# vim /etc/my.cnf 修改下面四行内容
 basedir = /data/soft/mysql
 datadir =  /data/mysqldb
 port = 3306
 server_id = 1　

加入path路径

[root@localhost mysql]# vim /etc/profile
PATH=/data/soft/mysql/bin:/data/soft/mysql/lib:$PATH  
export PATH

执行变量，让设置的路径生效

[root@localhost mysql]# source /etc/profile

加入系统服务中

[root@localhost mysql]# chkconfig mysqld on

启动数据库　

[root@localhost mysql]# systemctl start mysqld

查看是否启动完成

[root@localhost mysql]# ps -ef |grep mysqld
root      49740      1  0 19:58 ?        00:00:00 /bin/sh /data/soft/mysql/bin/mysqld_safe --datadir=/data/mysqldb --pid-file=/data/mysqldb/localhost.localdomain.pid
mysql     49908  49740 15 19:59 ?        00:00:01 /data/soft/mysql/bin/mysqld --basedir=/data/soft/mysql --datadir=/data/mysqldb --plugin-dir=/data/soft/mysql/lib/plugin --user=mysql --log-error=/data/mysqldb/localhost.localdomain.err --pid-file=/data/mysqldb/localhost.localdomain.pid --port=3306
root      49936   4132  0 19:59 pts/1    00:00:00 grep --color=auto mysqld　　

登录mysql并修改初次登陆密码

[root@localhost mysql]# mysql -uroot 
Welcome to the MySQL monitor.  Commands end with ; or g.

mysql> set password = password('m2i3sc');
Query OK, 0 rows affected (0.00 sec)

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

mysql> quit
Bye

　授权远程主机能够登陆mysql

mysql> create user nsh identified by '123456';
Query OK, 0 rows affected (0.00 sec)

mysql> grant all privileges on *.* to 'nsh'@'%' identified by '123456' with grant option; 
Query OK, 0 rows affected (0.07 sec)

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

 在本地用navicat测试连接情况，说明授权登陆成功。

好了，这是简单安装mysql5.6的版本，做出来比较简化，我看网上很多都是yum直接搞定，但是在生产环境我不建议这样做，后期维护非常麻烦，大量的数据在/（根）下，生产环境是直接挂在一块容量很大的硬盘上，所有数据都在这上面，这样减轻了服务器的压力，同时也方便维护，希望大家能够理解。
