mysql小白系列_02 mysql源码安装标准化

问题：

1.为何数据目录和日志目录须要分开?

2.如何标准化配置多实例?（例如：一台物理主机上部署3306与3307两个实例）

3.详细描述MySQL编译安装的过程（截图安装步骤）

---

1.为何数据目录和日志目录须要分开?

不一样做用的文件放到不一样的磁盘、目录之上

• 数据文件

  • 随机读写，能够放在高速盘上，如ssd、raid10
  • 追求响应时间

• 日志文件

  • 顺序写，能够放在raid5上
  • 若是用rsync同步到远端时，能够同步整个日记目录
  • 若是跟数据文件放在一块儿，数据文件会被一块儿同步过去
  • 追求吞吐量

2.如何标准化配置多实例?（例如：一台物理主机上部署3306与3307两个实例）

使用多个不一样配置文件
优势：配置简单
缺点：不方便管理

经过官方mysqld_mutil使用单独的配置文件
优势：方便集中管理
缺点：多个实例配置均在一个文件，不太方便

问题：

• 多个路径是否须要编译安装多个mysql软件？仍是共用一个mysql软件，而后根据不一样目录存放不一样数据库实例的data/log？
• 实际生产中是使用一个my.cnf文件配合mysqld_mutil工具管理实例？仍是每一个实例一个my.cnf文件？

编译安装单实例

1. 安装必要工具
   下面的安装源用5.6的

wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
yum install -y mysql57-community-release-el7-11.noarch.rpm https://dev.mysql.com/doc/refman/5.5/en/source-installation.html
yum install -y  cmake gcc gcc-c++ ncurses-devel bison zlib libxml openssl openssl-devel ncurses

 

1. 关闭防火墙
   不关闭也是能够的，打开对应的服务端口

• EL6

service iptables stauts service iptables stop chkconfig iptables off

• EL7
  7之后默认是firewall防火墙

firewall-cmd --state systemctl list-unit-files|grep firewalld.service systemctl status firewalld.service systemctl stop firewalld.service systemctl disable firewalld.service 或者 firewall-cmd --set-default-zone=trusted

1. 关闭SELINUX

getenforce setenforce 0
vi /etc/selinux/config permissive

1. 配置sysctl.conf
2. 检查操做系统上是否安装了MySQL

rpm -qa|grep -i mysql

1. 添加用户和组

groupadd mysql useradd mysql -g mysql -s /bin/false

1. 配MySQL环境变量
2. 建立目录及受权

mkdir -p /data/my3306/{data,log/binlog,log/iblog,run,tmp} chown -R mysql:mysql /data vi ~/.bash_profile PATH=$PATH:$HOME/bin:/data/my3306/bin export PATH

1. 解压mysql5.6

wget https://dev.mysql.com/get/Downloads/MySQL-5.6/MySQL-5.6.39-1.el7.src.rpm
rpm2cpio MySQL-5.6.39-1.el7.src.rpm | cpio -div tar -zxvf mysql-5.6.39.tar.gz

1. 编译并安装

cmake \ -DCMAKE_INSTALL_PREFIX=/data/my3306 \ -DINSTALL_DATADIR=/data/my3306/data \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DEXTRA_CHARSETS=all \ -DWITH_SSL=yes \ -DWITH_EMBEDDED_SERVER=1 \ -DENABLED_LOCAL_INFILE=1 \ -DWITH_MYISAM_STORAGE_ENGINE=1 \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_ARCHIVE_STORAGE_ENGINE=1 \ -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \ -DWITH_FEDERATED_STORAGE_ENGINE=1 \ -DWITH_PARTITION_STORAGE_ENGINE=1 \ -DMYSQL_UNIX_ADDR=/data/my3306/run/mysql.sock \ -DMYSQL_TCP_PORT=3306 \ -DENABLED_LOCAL_INFILE=1 \ -DSYSCONFDIR=/etc \ -DWITH_READLINE=on

结果

CMake Warning: Manually-specified variables were not used by the project: INSTALL_DATADIR WITH_READLINE -- Build files have been written to: /dvd/mysql-5.6.39

若是cmake失败，删除目录下的CMakeCache.txt文件

而后是make

[100%] Building CXX object mysql-test/lib/My/SafeProcess/CMakeFiles/my_safe_process.dir/safe_process.cc.o Linking CXX executable my_safe_process [100%] Built target my_safe_process

最后是make install

-- Up-to-date: /data/my3306/sql-bench/test-transactions -- Up-to-date: /data/my3306/sql-bench/test-wisconsin -- Installing: /data/my3306/sql-bench/cmake_install.cmake -- Installing: /data/my3306/sql-bench/CTestTestfile.cmake

1. MySQL参数配置
2. 初始化MySQL脚本

chown -R mysql:mysql /data cd /data/my3306 ./scripts/mysql_install_db --defaults-file=/data/my3306/my.cnf --datadir=/data/my3306/data --user=mysql

FATAL ERROR: please install the following Perl modules before executing ./mysql_install_db: Data::Dumper
报错了，须要安装Perl
yum install -y perl perl-devel perl-Data-Dumper
须要在bin目录下执行，否则会报错：FATAL ERROR: Could not find ./bin/my_print_defaults

1. 启动MySQL

cd /data/my3306/bin ./mysqld_safe --defaults-file=/data/my3306/my.cnf --user=mysql &

[root@mysql01 bin]# 180206 23:25:09 mysqld_safe error: log-error set to '/var/log/mariadb/mariadb.log', however file don't exists. Create writable for user 'mysql'.

1. 登陆MySQL

[root@mysql01 bin]# netstat -ano|grep 3306 tcp6 0      0 :::3306                 :::*                    LISTEN      off (0.00/0/0) unix 2      [ ACC ]     STREAM     LISTENING     57177    /data/my3306/run/mysql.sock [root@mysql01 bin]# mysql Welcome to the MySQL monitor.

在上面的基础，再初始化一个实例

1. 创建目录受权

mkdir -p /data/my3307/{data,log/binlog,log/iblog,run,tmp} chown -R mysql:mysql /data/my3307

2.修改my.cnf

cp -rp  /data/my3306/my.cnf /data/my3307/my.cnf sed -i {s/3306/3307/g} /data/my3307/my.cnf

basedir=/data/my3306 参数不变

1. 初始化数据库

cd /data/my3306/ ./scripts/mysql_install_db --defaults-file=/data/my3307/my.cnf --datadir=/data/my3307/data --user=mysql

1. 启动数据库服务

cd /data/my3306/bin ./mysqld_safe --defaults-file=/data/my3307/my.cnf --user=mysql &

1. 查看端口信息

[root@mysql01 bin]# netstat -lnptu|grep 330 tcp6 0      0 :::3306                 :::*                    LISTEN      off (0.00/0/0) tcp6 0      0 :::3307                 :::*                    LISTEN      off (0.00/0/0)

1. 登陆数据库

mysqld_mutil配置多个实例

1. 创建目录受权

mkdir -p /data/my3308/{data,log/binlog,log/iblog,run,tmp} chown -R mysql:mysql /data/my3308

　　2. 修改my.cnf 增长

basedir=/data/my3306 参数不变

1. 初始化数据库

cd /data/my3306 ./scripts/mysql_install_db --defaults-file=/data/my3306/my.cnf --datadir=/data/my3308/data --user=mysql

1. 启动数据库服务

cd /data/my3306/bin mysqld_multi --defaults-extra-file=/data/my3306/my.cnf start 1,2

180207 00:19:24 mysqld_safe Logging to '/data/my3306/log/error.log'. 180207 00:19:24 mysqld_safe The file /mysqld

启动信息以下：

mysqld_multi log file version 2.16; run: Wed Feb  7 10:43:34 2018 Starting MySQL servers 180207 10:43:35 mysqld_safe Logging to '/data/my3306/log/error.log'. 180207 10:43:35 mysqld_safe Logging to '/data/my3308/log/error.log'. 180207 10:43:35 mysqld_safe Starting mysqld daemon with databases from /data/my3306/data 180207 10:43:35 mysqld_safe Starting mysqld daemon with databases from /data/my3308/data

1. 查看端口信息

[root@mysql01 bin]# netstat -lnptu|grep 330 tcp6 0      0 :::3306                 :::*                    LISTEN      25185/mysqld tcp6 0      0 :::3307                 :::*                    LISTEN      26218/mysqld tcp6 0      0 :::3308                 :::*                    LISTEN      25197/mysqld

3.详细描述MySQL编译安装的过程（截图安装步骤）

1. 选择对应版本，下载源码包

https://dev.mysql.com/downloads/mysql/

1. 查看安装要求，必要的依赖包须要提早安装

https://dev.mysql.com/doc/refman/5.5/en/installing.html

1. 若是CMAKE里面有额外的参数，如SSL，还须要安装openssl openssl-devel
2. make的时候时间会很长，具体所需时间看机器配置
3. 实例运行用户须要对所需目录具备对应的读写权限，默认022通常足够
4. mysql_install_db初始化数据库时须要在basedir目录，由于要调用bin下面的my_print_defaults

$print_defaults = "$opt->{builddir}/extra/my_print_defaults";
$print_defaults = find_in_basedir($opt,"file","my_print_defaults","bin","extra");
$print_defaults='./bin/my_print_defaults';

3306和3308的配置以下:
