源码安装mysql

使用源码安装mysql，这里选择的版本是mysql5.7.35 ,系统是Centos7.6

官网下载地址：https://downloads.mysql.com/archives/community/

1. 下载源码压缩包

    [root@localhost ~]# cd /opt[root@localhost opt]# wget https://downloads.mysql.com/archives/get/p/23/file/mysql-boost-5.7.35.tar.gz[root@localhost opt]# tar -xf mysql-boost-5.7.35.tar.gz
   

2. 下载依赖软件

    [root@localhost ~]# yum install -y  cmake gcc  gcc-c++ ncurses-devel perl-Data-Dumper boost boost-doc boost-devel bzip2 openssl-devel libtirpc-devel.x86_64
   

3. 编译安装

    [root@localhost opt]# cd mysql-5.7.35/
   

   ## 新建目录，存放编译产生的中间文件。因为不允许在源码目录下进行编译

    [root@localhost mysql-5.7.35]# mkdir builder[root@localhost mysql-5.7.35]# cd builder/
   

   ## 编辑源码

    cmake ../ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/data/mysql -DSYSCONFDIR=/etc -DMYSQL_USER=mysql -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DMYSQL_TCP_PORT=3306 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8mb4 -DDEFAULT_COLLATION=utf8mb4_general_ci -DWITH_DEBUG=0 -DMYSQL_MAINTAINER_MODE=0 -DWITH_SYSTEMD=1 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=../boost

• -DENABLED_LOCAL_INFILE=1 启用加载本地数据

• -DENABLE_DOWNLOADS=1 编译时允许自主下载相关文件

• -DEXTRA_CHARSETS=all 使MySQL支持所有的扩展字符

• -DDEFAULT_CHARSET=utf8mb4 设置默认字符集为utf8mb4

• -DDEFAULT_COLLATION=utf8mb4_general_ci 设置默认字符校对

• -DWITH_DEBUG=0 禁用调试模式

• -DMYSQL_MAINTAINER_MODE=0 是否启用mysql维护器特定的开发环境

• -DDOWNLOAD_BOOST=1 允许在线更新boost库

• -DWITH_BOOST=…/boost 指定boost安装路径

  ## 生成二进制安装程序

    [root@localhost builder]# make
  

  ## 安装

    [root@localhost builder]# make install
  

4. 创建用户，创建目录，并授权
   ## 创建数据存放目录，编译的时候有指定目录，这里创建指定的目录即可

      [root@localhost builder]# mkdir -p  /data/mysql
   

   ## 创建日志存放目录，pid存放目录

      [root@localhost builder]# mkdir -p /var/log/mysqld /var/run/mysqld[root@localhost builder]# touch /var/run/mysqld/mysql.pid  [root@localhost builder]# touch /var/log/mysqld/mysqld.log
   

   ## 创建用户

      useradd --system -s /sbin/nologin mysql
   

   # 授权目录权限给用户

      [root@localhost ~]# chown -R mysql:mysql /var/log/mysqld		# 日志目录[root@localhost ~]# chown -R mysql:mysql /var/run/mysqld		# 存放目录[root@localhost ~]# chown -R mysql:mysql /usr/local/mysql/	# 安装目录[root@localhost ~]# chown -R mysql:mysql /data/mysql/        # 数据存放目录
   

5. 修改配置文件

    [root@localhost ~]# vim /etc/my.cnf
   

   [mysqld]
   basedir=/usr/local/mysql
   datadir=/data/mysql
   socket=/tmp/mysql.sock[mysqld_safe]
   log-error=/var/log/mysqld/mysqld.log
   pid-file=/var/run/mysqld/mysql.pid
   

6. 设置环境变量

    [root@localhost ~]# vim /etc/profile
   

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

   ## 加载环境变量，并测试

    source /etc/profilemysql --version
   

     mysql  Ver 14.14 Distrib 5.7.35, for Linux (x86_64) using  EditLine wrapper
   

7. 初始化数据库

   ## 初始化数据库，并生成临时密码

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

8. 将mysql加入到systemd进程中

    [root@localhost ~]# cd /opt/mysql-5.7.35/builder[root@localhost builder]# cp scripts/mysqld.service /usr/lib/systemd/system/
   

9. 启动mysql并修改密码

   ## 启动mysql并加入到开启自启

    [root@localhost ~]# systemctl  start mysqld [root@localhost ~]# systemctl  enable mysqld 
   

   ## 修改mysql密码
   在mysql初始化的时候会生成临时密码

    [root@localhost log]# mysql -uroot -p'Vm;n/i<44P(P'
