mysql5.7 源码安装

1、卸载系统自带mysql

    [root@localhost ~]# rpm -qa | grep mysql[root@localhost ~]# rpm -qa | grep mariadbmariadb-libs-5.5.60-1.el7_5.x86_64[root@localhost ~]# rpm -e --nodeps mariadb*[root@localhost ~]# yum remove mariadb-libs-5.5.60-1.el7_5.x86_64

2、添加mysql禁止登录的用户及目录规划

2.1、创建用户

useradd -M -s /sbin/nologin mysql

2.2、创建目录

[root@db02 ~/mysql-5.7.37]# cd /usr/local

   # 软件目录(为mysql安装目录创建软链接或改目录名)[root@db02 /usr/local]# ln -s  /usr/local/mysql-5.7.37 /usr/local/mysql# 数据目录[root@db02 /usr/local]# mkdir /usr/local/mysql-5.7.37/data# 日志目录[root@db02 /usr/local]# mkdir /var/log/mysql[root@db02 /usr/local]# touch /var/log/mysql/mysqld.log[root@db02 /usr/local]# chown -R mysql.mysql /var/log/mysql/mysqld.log# 其他目录（）[root@db02 /usr/local]# mkdir /usr/local/mysql-5.7.37/tmp[root@db02 /usr/local]# chown -R mysql.mysql /usr/local/mysql-5.7.37

3、下载、解压源码包

[root@db02 ~]# wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.37.tar.gz
[root@db02 ~]# tar xf mysql-5.7.37.tar.gz
[root@db02 ~]# cd mysql-5.7.37/

4、下载boost软件

#安装boots 一组C++ 库的集合,提供了线性代数、伪随机数生成、多线程、图像处理、正则表达式、单元测试等功能。

[root@db02 ~/mysql-5.7.37]# wget http://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
[root@db02 ~/mysql-5.7.37]# tar xf boost_1_59_0.tar.gz -C /usr/local

5、安装依赖

[root@db02 ~/mysql-5.7.37]# yum install -y ncurses-devel libaio-devel gcc gcc-c++ glibc cmake autoconf openssl openssl-devel libstdc++*  libtool lrzsz

6、进行cmake编译mysql源文件

cmake 通过编写cmakelist文件，自动生成makefile
#cmake一下

[root@db02 ~/mysql-5.7.37]# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql-5.7.37 \
-DMYSQL_DATADIR=/usr/local/mysql-5.7.37/data \
-DMYSQL_UNIX_ADDR=/usr/local/mysql-5.7.37/tmp/mysql.sock \
-DDOWNLOAD_BOOST=1 \
-DWITH_BOOST=/usr/local/boost_1_59_0 \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS=all \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
-DWITH_ZLIB=bundled \
-DWITH_SSL=system \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_EMBEDDED_SERVER=1 \
-DENABLE_DOWNLOADS=1 \
-DWITH_DEBUG=0

7、编译并安装

# make可以用来批处理.c或.cpp文件的，它从makefile中读取相应指令，然后编译。

[root@db02 ~/mysql-5.7.37]# make

# make install将 make 生成的文件安装到系统的对应目录中，比如从github上下载下来一个依赖库的安装包，解压后经过上面几步，该依赖库的对应头文件和库文件就安装到系统中了。

[root@db02 ~/mysql-5.7.37]# make install

#这条命令来进行安装（当然有些软件需要先运行 make check 或 make test来进行一些测试），这一步一般需要你有 root 权限（因为要向系统写入文件）

8、初始化数据库（初始化mysql数据库（建立默认的库和表））

#初始化注：1、初始化时，data目录必须为空，2、将随机生成的登录密码记录下来

[root@db02 /usr/local]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

9、编辑配置文件

   [root@db02 /usr/local]# vim /etc/my.cnf[mysqld]basedir=/usr/local/mysqldatadir=/usr/local/mysql/datasocket=/usr/local/mysql/tmp/mysql.sockpid-file=/usr/local/mysql/tmp/mysqld.pidport=3306character-set-server=utf8mb4log-error=/var/log/mysql/mysqld.log[mysql]character-set-server=utf8mb4socket=/usr/local/mysql/tmp/mysql.sock[client]character-set-server=utf8mb4socket=/usr/local/mysql/tmp/mysql.sock

10、测试连接

 [root@db02 /usr/local]# /usr/local/mysql/bin/mysql -uroot -p'0fkhCeNYFb*E'
