注意，在做實驗室統(tǒng)一關閉防火墻做的，在生產環(huán)境需要做防火墻規(guī)則的，大家要注意，做的時候盡量都是模仿生產環(huán)境的，比如服務一般都在/data/soft下面，盡量避免在/usr/local/下面。

安裝編譯mysql所需要的軟件

[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

創(chuàng)建mysql用戶，安裝目錄和數(shù)據(jù)目錄

[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

下載mysql5.6的源碼,注意有些版本下過來編譯會出現(xiàn)不兼容的情況，需要選擇cmake能夠兼容的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/

編譯安裝

[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目錄所有者和組

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

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

初始化數(shù)據(jù)目錄

[root@localhost mysql-5.6.16]# cd /data/soft/mysql

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

注意：此處出現(xiàn)問題了

# 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.

解決辦法為

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 修改下面四行內容

basedir = /data/soft/mysql

datadir = /data/mysqldb

port = 3306

server_id = 1

加入path路徑

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

PATH=/data/soft/mysql/bin:/data/soft/mysql/lib:$PATH

export PATH

執(zhí)行變量，讓設置的路徑生效

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

加入系統(tǒng)服務中

[root@localhost mysql]# chkconfig mysqld on

啟動數(shù)據(jù)庫

[root@localhost mysql]# systemctl start mysqld

查看是否啟動完成

[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

登錄mysql并修改初次登陸密碼

[root@localhost mysql]# mysql -uroot

Welcome to the MySQL monitor. Commands end with ; or \g.

Bye

授權遠程主機能夠登陸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測試連接情況，說明授權登陸成功。

好了，這是簡單安裝mysql5.6的版本，做出來比較簡化，我看網上很多都是yum直接搞定，但是在生產環(huán)境我不建議這樣做，后期維護非常麻煩，大量的數(shù)據(jù)在/(根)下，生產環(huán)境是直接掛在一塊容量很大的硬盤上，所有數(shù)據(jù)都在這上面，這樣減輕了服務器的壓力，同時也方便維護，希望大家能夠理解。
