一. 准备工作
1.yum安装各个依赖包
[root@WebServer ~]# yum �Cy install gcc gcc-devel gcc-c++ gcc-c++-devel zlib* ncurses-devel ncurses openssl openssl-devel bison bison-devel libaio
[root@WebServer ~]# yum �Cy install cmake
[root@WebServer user]# wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.20.tar.gz
2.新建mysql组和用户
[root@WebServer ~]# groupadd mysql
[root@WebServer ~]# useradd �Cg mysql �Cs /sbin/nologin mysql
3.目录准备
[root@WebServer ~]# mkdir �Cp /hywl/mysql/etc
[root@WebServer ~]# mkdir �Cp / hywl/mysql/data
[root@WebServer ~]# mkdir �Cp / hywl/mysql/tmp
[root@WebServer ~]# chown �CR mysql.mysql /hywl/mysql
4.解压MySQL并进入安装目录
拷贝mysql-5.6.20.tar.gz到/home/mysql目录下
[root@WebServer ~]# tar zxvf mysql-5.6.20.tar.gz
[root@WebServer ~]# cd mysql-5.6.20
二. 编译并安装
1 .下载gmock-1.6.0.zip到/home/mysql/mysql-5.6.20/source_downloads目录下并编译安装:
[root@WebServer mysql-5.6.20]# cd source_downloads/
[root@WebServer source_downloads]# unzip gmock-1.6.0.zip
root@WebServer source_downloads]# cd gmock-1.6.0
[root@WebServer gmock-1.6.0]# ./configure
[root@WebServer gmock-1.6.0]# make
[root@WebServer gmock-1.6.0]# cd ..
2.编译MySQL
[root@WebServer mysql-5.6.20]# cmake �CDCMAKE_INSTALL_PREFIX=/hywl/mysql
[root@WebServer mysql-5.6.20]# cmake -DSYSCONFDIR=/hywl/mysql/etc
[root@WebServer mysql-5.6.20]# cmake -DMYSQL_DATADIR=/hywl/mysql/data
[root@WebServer mysql-5.6.20]# cmake -DMYSQL_TCP_PORT=3306
[root@WebServer mysql-5.6.20]# cmake -DMYSQL_UNIX_ADDR=/hywl/mysql/tmp/mysqld.sock
[root@WebServer mysql-5.6.20]# cmake -DMYSQL_USER=mysql
[root@WebServer mysql-5.6.20]# cmake -DEXTRA_CHARSETS=all
[root@WebServer mysql-5.6.20]# cmake -DWITH_READLINE=1
[root@WebServer mysql-5.6.20]# cmake -DWITH_SSL=system
[root@WebServer mysql-5.6.20]# cmake -DWITH_EMBEDDED_SERVER=1
[root@WebServer mysql-5.6.20]# cmake -DENABLED_LOCAL_INFILE=1
[root@WebServer mysql-5.6.20]# cmake -DWITH_INNOBASE_STORAGE_ENGINE=1
[root@WebServer mysql-5.6.20]# cmake -DENABLE_DOWNLOADS=1
*如果出现错误,删除mysql-5.6.20目录下的CmakeCache.txt重新使用cmake进行编译安装
3.安装
[root@WebServer mysql-5.6.20]# make && make install
#时间有点长。
三.MySQL配置
1.客户端库文件的链接(未执行此步骤的话,在PHP编译时会提示找不到MySQL文件)
[root@WebServer mysql-5.6.20]# ln �Cs /hywl/mysql/lib/libmysqlclient.so.18 /usr/lib64/libmysqlclient.so.18
ps:我使用的是64位CentOS,如果使用的是32位请使用ln �Cs / hywl /mysql/lib/libmysqlclient.so.18 /usr/lib/libmysqlclient.so.18
2.MySQL启动文件的配置
[root@WebServer mysql-5.6.20]# cp support-files/mysql.server /etc/init.d/mysqld
[root@WebServer mysql-5.6.20]# chmod +x /etc/init.d/mysqld
[root@WebServer mysql-5.6.20]# vim /etc/init.d/mysqld
//修改以下这2行的路径即可
basedir=/hywl/mysql
datadir=/hywl/mysql/data
3.设置MySQL配置文件
[root@WebServer mysql-5.6.20]# cp support-files/my-default.cnf / hywl /mysql/etc/my.cnf
[root@WebServer mysql-5.6.20]# rm �Crf /etc/my.cnf
[root@WebServer mysql-5.6.20]# ln �Cs / hywl /mysql/etc/my.cnf /etc/my.cnf
4.初始化数据库
[root@WebServer mysql-5.6.20]# cd / hywl /mysql
[root@WebServer mysql]# ./scripts/mysql_install_db �Cuser=mysql �Cbasedir=/hywl/mysql �Cdatadir=/ hywl /mysql/data
5.链接MySQL命令(这一步可以让我们方便很多,可以不用写出命令的路径,也可以写入/etc/profile的PATH中)
可以修改环境变量:
[root@WebServer mysql]# vi /etc/profile
//增加一行:
export PATH=/hywl/mysql/bin:$PATH
[root@WebServer mysql]# source /etc/profile
//这时再查看系统环境变量,就能看见刚才加的东西已经生效了
[root@WebServer mysql]# echo $PATH
也可以:
[[root@WebServer mysql]#cd /usr/sbin
[root@WebServer sbin]# ln �Cs / hywl /mysql/bin/*
6.启动MySQL并设置为开机启动
[root@WebServer sbin]# service mysqld start ;chkconfig mysqld on
Starting MySQL.. SUCCESS!
7.设置MySQL root用户的密码
[root@WebServer ~]# mysqladmin �Cu root password mysql
//强烈不建议将数据库的密码设的简单
8.删除用户密码为空的用户
[root@WebServer ~]# mysql �Cu root �Cp
Enter password:
mysql> use mysql;
mysql> select Host,User,Password from user;
+-----------+------+-------------------------------------------+
| Host | User | Password |
+-----------+------+-------------------------------------------+
| localhost | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
| webserver | root | |
| 127.0.0.1 | root | |
| ::1 | root | |
| localhost | | |
| webserver | | |
+-----------+------+-------------------------------------------+
6 rows in set (0.00 sec)
mysql> delete from user where password=””;
Query OK, 5 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> select Host,User,Password from user;
+-----------+------+-------------------------------------------+
| Host | User | Password |
+-----------+------+-------------------------------------------+
| localhost | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |
+-----------+------+-------------------------------------------+
1 row in set (0.00 sec)
mysql> exit;
9.如何知道你的数据目录在哪里。如果你运行多个服务器,你应该知道所有数据目录在哪里,但是如果你不知道确切的位置,由多种方法找到它:
9.1使用mysqladmin variables从你的服务器直接获得数据目录路径名。查找datadir变量的值,在Unix上,其输出类似于:
%mysqladmin -u username -p variables
+----------------------+----------------------+
| variable_name | Value |
+----------------------+----------------------+
| back_log | 5 |
| connect_timeout | 5 |
| basedir | /var/local/ |
| datadir | /usr/local/var/ |
....
9.2查找mysql运行的路径
%ps -ef | grep mysqld
