CentOS的简单使用之配置编译MySQL（ 版本号:mysql-community-5.7.18-1.el7.src.rpm,主要参考官网方法）
一、编译安装MySQL前的准备工作
卸载mariadb;
yum -y remove mariadb*;

安装编译源码所需的工具和库
额外的知识点：lib库，dev开发，gdb调试。运行装lib，编译dev，调试装gdb；
c/c++编译器:
1.yum install gcc;
2.yum install gcc-c++ ;
注:使用yum命令安装可以不需要管依赖包;
gcc的依赖包：

Installing for dependencies:

libmpc x86_64 1.0.1-3.el7 base 51 k
g++的依赖包：

Installing for dependencies:
libstdc++-devel x86_64 4.8.5-11.el7 base 1.5 M
安装软件:
3.yum install ncurses-devel
perl一般都安装的有:
4.yum install perl 安装ntfs-3g:
wget ntfs-3g的地址,我是复制的官网的链接;
tar -xzvf 文件名 ;如果是GUI界面可以直接提取;
./configure
make
make install;
用man ntfs-3g测试看安装起了没有;
然后挂载;挂载ntfs文件系统 u盘:
网上有两种方法:一种是:安装内核模块;
mount /dev/sdb1 /mnt/usb -t ntfs;
另一种是在安装了ntfs-3g的前提下:
mount -t ntfs-3g /dev/sdb1 /mnt/usb
注:如果提示没有/mnt/usb 没有这个目录;就用mkdir /mnt/usb 建立一个;安装cmake(注:后面用了官方的方法,好像没有用到cmake;)
第一种方法:
wget http://www.cmake.org/files/v2.8/cmake-2.8.10.2.tar.gz
tar -xzvf cmake-2.8.10.2.tar.gz
cd cmake-2.8.10.2
./bootstrap ;
make ;
make install ;
man cmake;
第二种方法:
yum search cmake*;
yum install (如果上面搜索出来有cmake相关的包就可以安装,没有就用第一种方法;)
用man cmake 测试是否安装成功;安装rpmbuild:
yum search rpm-build;
如果有rpm-build，执行以下语句；
yum install rpm-build.x86_64;

二、设置MySQL用户和组
我使用的mysql版本(如果连接没有失效就可以下载,这是mysql官网链接):mysql-community-5.7.18-1.el7.src.rpm
新增mysql用户组：
groupadd mysql
新增mysql用户：
useradd -r -g mysql -s /bin/false mysql 三、安装boost
方法一:(此方法不太好,不完整,选用方法二吧)
会在rpmbuild的目录下生成解压后的文件;
7)这里进入/home/rpmbuild/BUILD/mysql.5.7.18/boost_1_59_0/
这里开始编译安装boost_1_59_0;
8）./bootstrap.sh;
执行./bootstrap.sh出现：
方法二:
在官网上下载好boost_1_59_0;
tar -zxvf boost_1_59_0
cd boost_1_59_0
./bootstrap.sh --with-libraries=system,filesystem,log,thread --with-toolset=gcc
./b2 toolset=gcc cxxflags="-std=c++11"
./b2 install --prefix=/usr/local/boost[root@localhost boost_1_59_0]# ./bootstrap.sh;
Building Boost.Build engine with toolset gcc... tools/build/src/engine/bin.linuxx86_64/b2
Detecting Python version... 2.7
Detecting Python root... /usr
Unicode/ICU support for Boost.Regex?... not found.
Generating Boost.Build configuration in project-config.jam...
Bootstrapping is done. To build, run:
./b2
To adjust configuration, edit 'project-config.jam'.
Further information:
- Command line help:
./b2 --help
- Getting started guide:
http://www.boost.org/more/getting_started/unix-variants.html
- Boost.Build documentation:
http://www.boost.org/build/doc/html/index.html
[root@localhost boost_1_59_0]#
运行 ./b2 出现以下的问题（注：没有出现错误，跳到步骤12）开始执行）：
./boost/python/detail/wrap_python.hpp:50:23: fatal error: pyconfig.h: No such file or directory
和
libs/iostreams/src/bzip2.cpp:20:56: error: bzlib.h: 没有那个文件或目录
也就是在安装过程出现很多和bz及Python库相关的错误，解决方案如下:
9）yum install bzip2-devel.x86_64;
10）yum install python-devel;
安装好库后
11）删除/root/rpmbuild/BUILD/ 下的全部文件，再次从步骤3）开始执行；
直到运行./bootstrap.sh后出现：
The Boost C++ Libraries were successfully built!
The following directory should be added to compiler include paths:
/root/rpmbuild/BUILD/mysql-5.7.18/boost_1_59_0
The following directory should be added to linker library paths:
/root/rpmbuild/BUILD/mysql-5.7.18/boost_1_59_0/stage/lib
12）最后就是安装boost：
./b2 install --prefix=/usr/local
13）到这里mysql必需的库boost安装完成；
四、从这里开始安装mysql了:
###第一次安装(源代码安装,可以这么说):
前提:先安装下面四个依赖包:
libaio-devel is needed by mysql-community-5.7.18-1.el7.centos.x86_64
ncurses-devel is needed by mysql-community-5.7.18-1.el7.centos.x86_64
numactl-devel is need000000000000000000000ed by mysql-community-5.7.18-1.el7.centos.x86_64
openssl-devel is needed by mysql-community-5.7.18-1.el7.centos.x86_64
0)把 前提 中的依赖包安装好后在执行 步骤 1) ;
1）rpmbuild --rebuild --clean mysql-community-5.7.18-1.el7.src.rpm ;步骤1）为官网方法；
执行步骤1）后会在/root/rpmbuild/RPMS/下生成x86_64文件：
文件中有10个可安装的程序：
mysql-community-client-5.7.18-1.el7.centos.x86_64.rpm；
mysql-community-common-5.7.18-1.el7.centos.x86_64.rpm
mysql-community-devel-5.7.18-1.el7.centos.x86_64.rpm；
mysql-community-embedded-5.7.18-1.el7.centos.x86_64.rpm
mysql-community-embedded-compat-5.7.18-1.el7.centos.x86_64.rpm
mysql-community-embedded-devel-5.7.18-1.el7.centos.x86_64.rpm
mysql-community-libs-5.7.18-1.el7.centos.x86_64.rpm
mysql-community-libs-compat-5.7.18-1.el7.centos.x86_64.rpm
mysql-community-server-5.7.18-1.el7.centos.x86_64.rpm
mysql-community-test-5.7.18-1.el7.centos.x86_64.rpm
安装:
rpm -ivh mysql-community-{server,client,common,libs}-* ;
再一次安装,与第一次安装的不一样;
我下的mysql是一个名称为:(mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar)
我使用是解压命令:
tar -xvf mysql-5.7.20-1.el7.x86_64.rpm-bundle.tar; 注意不能有z;
解压后的文件夹(共9个):
mysql-community-embedded-devel-5.7.20-1.el6.x86_64.rpm
mysql-community-client-5.7.20-1.el6.x86_64.rpm
mysql-community-libs-5.7.20-1.el6.x86_64.rpm
mysql-community-common-5.7.20-1.el6.x86_64.rpm
mysql-community-libs-compat-5.7.20-1.el6.x86_64.rpm
mysql-community-devel-5.7.20-1.el6.x86_64.rpm
mysql-community-server-5.7.20-1.el6.x86_64.rpm
mysql-community-embedded-5.7.20-1.el6.x86_64.rpm
mysql-community-test-5.7.20-1.el6.x86_64.rpm在运行了 rpm -ivh mysql-community-{server,client,common,libs}-* ;这句话的时候,出现了错误;
warning: mysql-community-server-5.7.20-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:
libsasl2.so.2()(64bit) is needed by mysql-community-server-5.7.20-1.el6.x86_64解决方法:
1.我在pkgs.org上下载了cyrus-sasl-lib-2.1.23-15.el6_6.2.x86_64.rpm ,下载完后并安装了;
但是因为安装cyrus-sasl-lib-2.1.23-15...需要依赖的东西太多,我使用了
yum install cyrus-sasl-lib;
2.但是步骤 1 做完后好像还是不行,我在继续寻求别的方法;
解决...: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY....这个问题;
我在网上搜索到的解决方法是:在rpm -ivh **** 后面加上 --force --nodeps;
完整命令:
rpm -ivh mysql-community-{server,client,common,libs}-* --force --nodeps;
在运行完成后:
我启动mysql,发现可以启动,并且用service mysqld status查看服务状态,也发现存在mysql服务;
总结:我不是知道步骤 1 到底有没有效果,待以后再次使用是在说,先把先把事干完再说;
接下来,可以配置和初始化mysql了;配置和初始化mysql:
启动mysql:
service mysqld start #centos 7 and up 中不在是这个命令启动服务了;
/bin/systemctl start mysqld.service ; #在CentOS and up 用这个启动mysql服务;
/bin/systemctl stop mysqld.service ; #在CentOS and up 用这个关闭mysql服务;
官方文档:A superuser account 'root'@'localhost' is created. A password for the superuser is set and stored in the error log file. To reveal it, use the following command for RHEL, Oracle Linux, CentOS, and Fedora systems:
翻译:一个超级用户账户'root'@'localhost'被创建,一个超级用户的密码被设置并且保存在错误日志中,
在RHEL, Oracle Linux, CentOS, and Fedora系统中使用以下命令查看:
注: temporary 的意思是临时的;
grep 'temporary password' /var/log/mysqld.log
mysql -u root -p #
Enter password: 输入临时密码
mysql >ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPassword!'; #修改密码,注意密码的强度,太弱不会被通过;配置mysql可以用Navicat远程连接
说明:来源：Linux社区 作者：shuaiding ,完整内容请点击这里
1.允许root用户在任何地方进行远程登录，并具有所有库任何操作权限，具体操作如下：
在本机先使用root用户登录mysql：
mysql -u root -p"youpassword"
进行授权操作：
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'youpassword' WITH GRANT OPTION;
重载授权表：
FLUSH PRIVILEGES;
退出mysql数据库：
exit
