先安装： yum -y install wget gcc-c ncurses ncurses-devel cmake make perl bison openssl openssl-devel gcc* libevent libevent-devel libxml2 libxml2-devel libmcrypt libmcrypt-devel curl-devel libpng-devel libtool-ltdl-devellibjpeg* libpng* fr

先安装：

yum -y install wget gcc-c++ ncurses ncurses-devel cmake make perl bison openssl openssl-devel gcc* libevent libevent-devel libxml2 libxml2-devel libmcrypt libmcrypt-devel curl-devel libpng-devel libtool-ltdl-devel libjpeg* libpng* freetype* zlib zlib-devel openldap openldap-devel libxslt-devel* bzip2-devel

1.建立数据库文件目录 如：mkdir /mysqldata

2.下载mysql-5.6.15.tar.gz,并解压

3.运行

cmake \

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \

-DMYSQL_DATADIR=/mysqldata \

-DSYSCONFDIR=/etc \

-DWITH_MYISAM_STORAGE_ENGINE=1 \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_MEMORY_STORAGE_ENGINE=1 \

-DWITH_READLINE=1 \

-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \

-DMYSQL_TCP_PORT=3306 \

-DENABLED_LOCAL_INFILE=1 \

-DWITH_PARTITION_STORAGE_ENGINE=1 \

-DEXTRA_CHARSETS=all \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci

注意datadir和DMYSQL_UNIX_ADDR要分别对应my.cnf里面的datadir和socket

4.make && make install

5. cat /etc/passwd 查看用户列表

cat /etc/group 查看用户组列表

如果没有就创建用户组和用户名：

groupadd mysqluser

add -g mysql mysql

创建相关目录：

mkdir /mysqldata/

mkdir /mysqldata/logs

chown -R mysql:mysql /mysqldata

chown -R mysql:mysql /mysqldata/logs

修改安装目录权限：chown -R mysql:mysql /usr/local/mysql

进入安装目录

cd /usr/local/mysql

删除/etc/my.cnf

vim /usr/local/mysql/my.cnf

[mysqld]

datadir = /mysqldata

socket = /var/lib/mysql/mysql.sock

pid-file = /mysqldata/logs/mysql.pid

user = mysql

port = 3306

default_storage_engine = InnoDB

# InnoDB

#innodb_buffer_pool_size = 128M

#innodb_log_file_size = 48M

innodb_file_per_table = 1

innodb_flush_method = O_DIRECT

# MyISAM

#key_buffer_size = 48M

# character-set

character-set-server=utf8

collation-server=utf8_general_ci

# name-resolve

skip-host-cache

skip-name-resolve

# LOG

log_error = /mysqldata/logs/mysql-error.log

long_query_time = 1

slow-query-log

slow_query_log_file = /mysqldata/logs/mysql-slow.log

# Others

explicit_defaults_for_timestamp=true

#max_connections = 500

open_files_limit = 65535

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

[client]

socket = /var/lib/mysql/mysql.sock

port = 3306

安装自带数据库：

/usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/mysqldata --user=mysql

注意目录设置要与上面编译的时候一致

ps:如果此处遇到权限不够的错误，请将mysql_install_db 的权限+x

chmod +x mysql_install_db

6.添加开机启动和设置服务

配置my.cnf，配置好后，需要设置权限

chmod -R 755 my.cnf

chown -R mysql:mysql my.cnf

cp support-files/mysql.server /etc/init.d/mysql

chkconfig mysql on

chmod 755 /etc/init.d/mysql

service mysql start --启动MySQL

7.MySQL启动成功后，root默认没有密码，我们需要设置root密码。

设置之前，我们需要先设置PATH，要不不能直接调用mysql

修改/etc/profile文件，在文件末尾添加

PATH=/usr/local/mysql/bin:$PATH

export PATH

关闭文件，运行下面的命令，让配置立即生效

source /etc/profile

现在，我们可以在终端内直接输入mysql进入，mysql的环境了

执行下面的命令修改root密码

mysql -uroot

mysql> SET PASSWORD = PASSWORD('123456');

mysql>flush privileges;

若要设置root用户可以远程访问，执行

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'172.16.%' IDENTIFIED BY 'password' WITH GRANT OPTION;
