源码方式安装   mysql-boost-5.7.17.tar.gz

1、 准备工作

              关闭SELinux,    防火墙   下载软件包   ------>https://www.mysql.com/ 

       卸载自带的mariadb           

2、卸载系统自带的mariadb软件

    [root@mysqltest ~]# rpm -qa | grep mariadb

    mariadb-libs-5.5.44-2.el7.centos.x86_64

    [root@mysqltest ~]# rpm -e --nodeps mariadb-libs

3、创建数据目录   /mydata/data

     [root@mysqltest ~]# mkdir -p /mydata/data

    修改数据目录的所属

    [root@node02 ~]# useradd -s /sbin/nologin -M mysql

    [root@node02 ~]# chown -R mysql.mysql /mydata/data/

4、安装cmake编译器 

    [root@node02 ~]# yum install -y cmake

    [root@node02 ~]# tar zxf mysql-boost-5.7.17.tar.gz 

                         cmake. -L  查看cmake支持的编译选项

[root@node02 ~]# cd mysql-5.7.17/

[root@mysql57 mysql-5.7.17]# cmake . \

-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \

-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \

-DDEFAULT_CHARSET=utf8 \

-DDEFAULT_COLLATION=utf8_general_ci \

-DMYSQL_DATADIR=/mydata/data \

-DMYSQL_TCP_PORT=3306 \

-DWITH_BOOST=boost/boost_1_59_0/ \

-DWITH_MYISAM_STORAGE_ENGINE=1 \

-DWITH_INNOBASE_STORAGE_ENGINE=1 \

-DWITH_ARCHIVE_STORAGE_ENGINE=1 \

-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \

错误1：

CMake Error: your C compiler: "CMAKE_C_COMPILER-NOTFOUND" was not found.   Please set CMAKE_C_COMPILER to a valid compiler path or name.

CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found.   Please set CMAKE_CXX_COMPILER to a valid compiler path or name.

CMake Error at cmake/os/Linux.cmake:41 (MESSAGE):

  Unsupported compiler!

Call Stack (most recent call first):

  CMakeLists.txt:162 (INCLUDE)

解决办法：

# yum groupinstall -y "Development Tools" "Server Platform Development" "Desktop Platform Development"

错误2：

CMake Error at cmake/readline.cmake:64 (MESSAGE):

  Curses library not found.  Please install appropriate package,

解决办法： 

[root@node02 ~]# yum install -y ncurses-devel.x86_64 

[root@mysqltest mysql-5.7.17]# make

[root@mysqltest mysql-5.7.17]# make install

[root@mysqltest ~]# chown -R root.mysql /usr/local/mysql/

5、初始化数据库

[root@mysql57 ~]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/mydata/data

6、复制MySQL配置文件 

[root@node02 ~]# cd /usr/local/mysql/support-files/

[root@node02 support-files]# cp my-default.cnf /etc/my.cnf

[root@node02 support-files]# vim /etc/my.cnf

[mysqld]

...

basedir=/usr/local/mysql

datadir=/mydata/data

port=3306

server_id=121

socket=/tmp/mysql.sock

7、启动mysql服务 

[root@mysqltest data]# /usr/local/mysql/bin/mysqld_safe --user=mysql &

[root@mysqltest data]# ss -antp | grep mysqld

LISTEN     0      80          :::3306                    :::*                   users:(("mysqld",pid=63756,fd=20))

[root@mysqltest data]# 

8、修改环境变量PATH

 [root@mysqltest] export PATH=$PATH:/usr/local/mysql/bin    临时的

 [root@mysqltest] echo $PATH

[root@mysqltest data]# cat /etc/profile.d/mysql.sh 

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

[root@mysqltest data]# source /etc/profile.d/mysql.sh

[root@mysqltest data]# mysql -u root -p

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Www.1.com';

mysql> FLUSH PRIVILEGES;

Query OK, 0 rows affected (0.00 sec)

9、设置源码mysql服务开机自启动  

# vim /etc/rc.d/rc.local 

/usr/local/mysql/bin/mysqld_safe --user=mysql &
