Adakah sesiapa mempunyai tutorial terperinci mengenai pemasangan mysql5.7?

Question

Saya rasa memasang nginx dan php agak mudah, tetapi mysql lebih menyusahkan

Pengenalan di laman web rasmi tidak begitu terperinci Contohnya, tiada perbezaan antara pengguna kerja dan root, langkah pemasangan tidak boleh diikuti, kebenaran setiap direktori, dll.

Terdapat blog Zhang Yan yang sangat terperinci, tetapi sudah lama tidak dikemas kini.

Answer 1

虽然MySQL可以用命令行安装，但是会对一些细节和不可控性不了解,所以选择源码安装
最新版本需要用boost库，所以要下载 mysql 和 boost, 下载链接如下:

    http://dev.mysql.com/downloads/mysql/ 
   
    选择source code,下载最后两个安装包: mysql-5.7.14.tar.gz, mysql-boost-5.7.14.gz
    http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.14.tar.gz
    http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.14.tar.gz

1 安装MySQL

1.1 下载

    wget http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.14.tar.gz
    wget http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.14.tar.gz


1.2 解压

    先解压mysql-5.7.14.tar.gz, 然后再解压mysql-boost-5.7.14.tar.gz
    这样能保证boost能解压到mysql-5.7.14/boost目录下

    tar -xvf mysql-5.7.14.tar.gz
    tar -xvf mysql-boost-5.7.14.tar.gz

1.3 安装

1.3.1 安装MySQL必须库

    apt-get update
    apt-get install bison openssl libncurses5-dev perl cmake

1.3.2 编译安装

    进入目录安装

    cd mysql-5.7.14  

    cmake . \
    -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
    -DMYSQL_DATADIR=/opt/data/mysql/data \
    -DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
    -DDEFAULT_CHARSET=utf8 \
    -DDEFAULT_COLLATION=utf8_general_ci \
    -DWITH_EXTRA_CHARSETS=all \
    -DWITH_MYISAM_STORAGE_ENGINE=1 \
    -DWITH_INNOBASE_STORAGE_ENGINE=1 \
    -DWITH_MEMORY_STORAGE_ENGINE=1 \
    -DWITH_READLINE=1 \
    -DENABLED_LOCAL_INFILE=1 \
    -DMYSQL_USER=mysql \
    -DWITH_BOOST=boost

    make && make install 

2.配置MySQL
    
    根据步骤1，MySQL安装在/usr/local/mysql目录下

    cd /usr/local/mysql
    ls 
    可以查看mysql目录

2.1 创建MySQL用户

    groupadd mysql
    useradd mysql -g mysql

2.2 创建MySQL数据目录,用来存储MySQL数据

    mkdir -p /opt/data/mysql/data            # 存放MySQL数据库数据
    mkdir -p /opt/data/mysql/log             # 存放MySQL日志，查看日常操作log和异常
    mkdir -p /opt/data/mysql/bin-log         # 存放MySQL bin log日志，用来同步数据
    chown -R mysql:mysql /opt/data/mysql     # root用户将mysql目录归mysql用户所有

2.3 配置MySQL
    cd /usr/local/mysql
    cp support-files/my-default.cnf /etc/my.cnf     # 将my-default.cnf文件复制到/etc目录下，并命名为my.cnf
    vim /etc/my.cnf     # 打开my.cnf, 添加如下配置:

[mysqld]
character_set_server=utf8

server_id = 1
port = 3306

innodb_buffer_pool_size = 128M
basedir = /usr/local/mysql
datadir = /opt/data/mysql/data
socket = /tmp/mysql.sock
pid-file = /opt/data/mysql/mysql.pid 

log-bin = /opt/data/mysql/bin-log/mysql-bin 
sync-binlog = 1 

general_log = 1    
log-error = /opt/data/mysql/log/mysql_err.log
general_log_file = /opt/data/mysql/log/mysql.log

[mysql]
default-character-set=utf8


2.4 初始化MySQL 

    cd /usr/local/mysql
    bin/mysqld  --defaults-file=/etc/my.cnf --user=mysql --initialize

    打开/opt/data/mysql/log/mysql.log, 查找初始化密码

    2016-07-05T08:31:20.363565Z 1 [Note] A temporary password is generated for root@localhost: 9arAj*:r047g

    登陆 
    bin/mysql -u root -p 9arAj*:r047g 

    不修改密码不能操作
    mysql> show databases;
    ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
    
    修改密码
    mysql> SET PASSWORD = PASSWORD('123456');
    mysql> ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
    mysql> flush privileges;

2.5 配置MySQL执行路劲

    vim /root/.bashrc    # 打开.bashrc文件，并记录一下内容

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

    保存，退出

    source /root/.bashrc

    执行一下命令检验是否准确
    
    mysql -uroot -p123456
