1 查看机器上是否装有mysql
rpm -qa | grep mysql
2. 删除已经存在的mysql
rpm -e --nodeps mysql ()强力删除模式)
3.安装编译代码需要的包
yum -y install gcc gcc-devel gcc-c++ gcc-c++-devel autoconf* automake* zlib* libxml* ncurses-devel ncurses libgcrypt* libtool* cmake openssl openssl-devel bison bison-devel unzip -y
4. 解压编译：tar -zxvf mysql-5.6.14.tar.gz
cd mysql-5.6.14
编译安装： mysql5.5以后编译安装使用cmake
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-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
*********************************************************************
如果出现一下错误：
cmake .
-- MySQL 5.5.8
-- Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)
CMake Error at cmake/readline.cmake:82 (MESSAGE):
Curses library not found. Please install appropriate package,
remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel.
Call Stack (most recent call first):
cmake/readline.cmake:126 (FIND_CURSES)
cmake/readline.cmake:216 (MYSQL_USE_BUNDLED_LIBEDIT)
CMakeLists.txt:256 (MYSQL_CHECK_READLINE)
-- Configuring incomplete, errors occurred!
则需要安装 yum -y install ncurses-devel -y *******而且删除掉 CMakeCache.txt 这个文件。重新再编译一次就OK
5 make && make install
6. 创建mysql用户和mysql组
groupadd mysql
useradd -s /sbin/nologin -g mysql -M mysql
-M:不创建家目录
7.修改/usr/local/mysql权限
chown -R mysql:mysql /usr/local/mysql
8.。。
进入安装路径，执行初始化配置脚本，创建系统自带的数据库和表
cd /usr/local/mysql
scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
9 启动数据库
/usr/local/mysql/bin/mysqld_safe &
10 添加服务，拷贝服务脚本到init.d目录
cp support-files/mysql.server /etc/init.d/mysqld
chkconfig mysql on
/etc/init.d/mysqld start
11 配置mysql全局使用路径
vim /etc/profile
增加 PATH=$PATH:/usr/local/mysql/bin/
echo $PATH
12: source /etc/profile
使路径生效
13 mysql登陆命令
mysql -u root -p
修改mysql登陆密码（默认为空）
mysqladmin -u root password ‘123456‘
15查看系统自带表
mysql>show databases;
16 若要设置root用户可以远程访问，执行
mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘192.168.%‘ IDENTIFIED BY ‘123456‘ WITH GRANT OPTION; 红色的password为远程访问时，root用户的密码，可以和本地不同。
17 防火墙的3306端口默认没有开启，若要远程访问，需要开启这个端口
Vim /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p -dport 3306 -j ACCEPT
