1、关闭防火墙

service iptables stop

chkconfig iptables off

setenforce 0

vi /etc/selinux/config

SELINUX=permissive

2、配置sysctl.conf

主要配置shmmax共享内存类参数，最大设置为50%-60%系统物理内存。

3、检查操作系统是否安装了MysqL

如果需要删除MysqL，可以执行：

rpm -e MysqL-libs-5.1.66-2.el6_3.x86_64

如果因为依赖删不掉，则可以用yum来删：

yum remove MysqL-libs-5.1.66-2.el6_3.x86_64

再检查一下MysqL的安装包是否存在：

4、下载MysqL源码包

[root@MysqL yum.repos.d]# mkdir /u01

[root@MysqL yum.repos.d]# cd /u01

[root@MysqL u01]#

配置ftp，上传源码

a、配置源http://blog.csdn.net/kadwf123/article/details/78231694

b、配置ftp服务

yum -y install vsftpd

chkconfig vsftpd on

cd /etc/vsftpd

vi ftpusers

把root用户注释掉

vi user_list

把root用户注释掉

5、添加用户和组

groupadd MysqL

创建MysqL组

创建MysqL用户

设置MysqL用户的密码：

6、配置MysqL环境变量

su - MysqL

vi .bash_profile

修改path变量：

使之生效

7、创建目录及授权

[root@MysqL vsftpd]# mkdir -p /u01/my3306/data

[root@MysqL vsftpd]# mkdir -p /u01/my3306/log/iblog

[root@MysqL vsftpd]# mkdir -p /u01/my3306/log/binlog

[root@MysqL vsftpd]# mkdir -p /u01/my3306/run

[root@MysqL vsftpd]# mkdir -p /u01/my3306/tmp

[root@MysqL vsftpd]#

授权：

[root@MysqL vsftpd]# chown -R MysqL:MysqL /u01/my3306

[root@MysqL vsftpd]# chmod -R 755 /u01/my3306

[root@MysqL vsftpd]#

8、解压MysqL5.6

tar -xzvf MysqL-5.6.39.tar.gz

9、配置yum源，安装cmake

yum install -y cmake gcc gcc-c++ ncurses-devel bison zlib libxml openssl openssl-devel ncurses

安装上面的所有的依赖包，确保安装成功。

10、编译并安装

进入MysqL源码包的解压目录

执行如下命令：

cmake \

-DCMAKE_INSTALL_PREFIX=/u01/my3306 \

-DINSTALL_DATADIR=/u01/my3306/data \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci \

-DMysqL_TCP_PORT=3306 \

-DENABLED_LOCAL_INFILE=1 \

-DSYSCONFDIR=/etc \

-DWITH_READLINE=on

失败，老是报错：

[root@MysqL MysqL-5.6.39]# ll
注意这个地方：

怀疑是openssl导致的，但是我的openssl检查却装了。

没办法，下一个在装，然后指定：

-DOPENSSL_ROOT_DIR=/usr/local/openssl \

-DOPENSSL_LIBRARIES=/usr/local/openssl/lib \

这两项。完整命令如下：

cmake \

-DCMAKE_INSTALL_PREFIX=/u01/my3306 \

-DMysqL_DATADIR=/u01/my3306/data \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci \

-DEXTRA_CHARSETS=all \

-DWITH_SSL=yes \

-DWITH_EMBEDDED_SERVER=1 \

-DENABLED_LOCAL_INFILE=1 \

-DWITH_MYISAM_STORAGE_ENGINE=1 \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_ARCHIVE_STORAGE_ENGINE=1 \

-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \

-DWITH_FEDERATED_STORAGE_ENGINE=1 \

-DWITH_PARTITION_STORAGE_ENGINE=1 \

-DMysqL_UNIX_ADDR=/u01/my3306/run/MysqL.sock \

-DMysqL_TCP_PORT=3306 \

-DENABLED_LOCAL_INFILE=1 \

-DSYSCONFDIR=/etc \

-DOPENSSL_ROOT_DIR=/usr/local/openssl \

-DOPENSSL_LIBRARIES=/usr/local/openssl/lib \

-DWITH_READLINE=on

下面说明使用二进制包安装openssl：

a、下载新版openssl安装包：https://www.openssl.org/source/

b、把安装文件openssl-1.0.2n.tar.gz上传到虚拟机。

c、tar -xzvf openssl-1.0.2n.tar.gz

d、cd openssl-1.0.2n

e、执行命令：./config --prefix=/usr/local/openssl -fPIC no-gost no-shared no-zlib

注意，如果不指定 -fPIC选项，可能会出现如下错误：

[root@MysqL MysqL-5.6.39]#

主要注意：

f、执行命令：make depend

g、执行命令：./config -t

h、执行make，编译openssl。注意执行make要有gcc编译器。

i、执行make install进行安装。

j、执行cd /usr/local

k、执行ldd /usr/local/openssl/bin/openssl

l、配置环境变量：PATH=/usr/local/openssl/bin:$PATH:$HOME/bin

m、使环境变量生效source /root/.bash_profile

n、which openssl

o、查看版本：openssl version

然后就可以执行cmake成功了：

多次cmake需要删除CMakeCache.txt 文件

cd/u01/MysqL-5.6.39/

rm -fCMakeCache.txt

下面直接进行make编译：

make

这条命令执行的时间比较长，前台一直会输出make的进度：

然后还需要执行make install安装到指定目录/u01/my3306中。

11、MysqL参数配置

把my.cnf参数文件直接传到/u01/my3306/目录下面去。

也可以直接建一个my.cnf，内容如下：

[client]
port=3306
socket=/u01/my3306/MysqL.sock

[MysqL]
pid_file=/u01/my3306/run/MysqLd.pid

[MysqLd]

[MysqLd_safe]
datadir=/u01/my3306/data

然后把/u01/my3306目录属主改成MysqL

chown -R MysqL:MysqL /u01/my3306

12、初始化MysqL脚本

cd /u01/my3306/scripts

./MysqL_install_db --help

./scripts/MysqL_install_db --defaults-file=/u01/my3306/my.cnf --datadir=/u01/my3306/data --user=MysqL

注意此命令要在/u01/my3306目录下执行。

13、启动MysqL

[MysqL@MysqL bin]$ pwd

/u01/my3306/bin

[MysqL@MysqL bin]$ ./MysqLd_safe --defaults-file=/u01/my3306/my.cnf --user=MysqL &

检查MysqL进程：

14、登录MysqL

登录MysqL
