  • lamp 相关mysql的安装

    1、LAMP = linux + apache + mysql(mariadb/mongodb) + php

    2、mysql 安装:
    先下载安装包:

    wget -c  http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz

    解压: tar -xvf  mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz

    移动到: mv ./mysql-5.6.36-linux-glibc2.5-x86_64 /usr/local/mysql56

    cd /usr/local/mysql56

    创建用户:

    useradd -M mysql -s /sbin/nologin

    ./scripts/mysql_install_db --user=mysql  --datadir=./data/mysql

    若报这个错:

    FATAL ERROR: please install the following Perl modules before executing ./scripts/mysql_install_db:
    Data::Dumper

    需要安装:

    [root@one_year mysql56]#yum list |grep Dumper
    perl-Data-Dumper.x86_64 2.145-3.el7 base
    perl-Data-Dumper-Concise.noarch 2.020-6.el7 epel
    perl-Data-Dumper-Names.noarch 0.03-17.el7 epel
    perl-XML-Dumper.noarch 0.81-17.el7 base
    [root@one_year mysql56]# yum install perl-Data-Dumper.x86_64 -y

    安装perl模块:yum install perl-Data-Dumper.x86_64 -y

    若报错:

    Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

    [root@one_year bin]# yum list | grep libaio
    libaio.i686 0.3.109-13.el7 base
    libaio.x86_64 0.3.109-13.el7 base
    libaio-devel.i686 0.3.109-13.el7 base
    libaio-devel.x86_64 0.3.109-13.el7 base
    [root@one_year bin]# yum install^C
    [root@one_year bin]# yum install libaio.x86_64 libaio-devel.x86_64 -y

    再进行安装:

    ./scripts/mysql_install_db --user=mysql --datadir=./data/mysql

    然后,再复制配制文件:

    cp support-files/my-default.cnf /etc/my.cnf

    修改:/etc/my.cnf

     

    再复制:cp support-files/mysql.server /etc/init.d/mysqld

    再修改vim /etc/init.d/mysqld

     直接用命令启的方式:

    /usr/local/mysql56/bin/mysqld_safe --defaults-file=/etc/my.cnf --user=mysql --datadir=/usr/local/mysql56/data/mysql &

    mysql服务的开启和关闭:

    /etc/init.d/mysqld start

    /etc/init.d/mysqld stop

    3、mariaDB的安装:

    下载安装包:

    wget -c https://downloads.mariadb.com/MariaDB/mariadb-10.3.6/bintar-linux-glibc_214-x86_64/mariadb-10.3.6-linux-glibc_214-x86_64.tar.gz

    解压:

    tar -xvf mariadb-10.3.6-linux-glibc_214-x86_64.tar.gz 

     移动并重命名:

    mv ./mariadb-10.3.6-linux-glibc_214-x86_64  /usr/local/mariadb1036

    进入该目录:

    cd /usr/local/mariadb1036/

    创建一个用户:

    useradd -M mariadb -s /sbin/nologin

    安装:

     ./scripts/mysql_install_db --user=mariadb  --basedir=/usr/local/mariadb1036/ --datadir=./data/mysql/

    复制: cp  ./support-files/mysql.server /etc/init.d/mariadbd

    编辑:/etc/init.d/mariadbd

      指定相关路径:

    basedir=/usr/local/mariadb1036/
    datadir=/data/mysql/
    conf=/usr/local/mariadb1036/my.cnf

    $bindir/mysqld_safe --user="mariadb" --datadir="$datadir" --pid-file="$mysqld_pid_file_path" "$@" &
    wait_for_ready; return_value=$?

    在启动的时候,用这个用户,不然后,无法启动,因为在安装的时候用的是这个用户

    进行配制文件的配制:

    /etc/my.cnf  

    这个根据自己的实际情况配制。

      配制socket路径:

      socket = /tmp/mysqld.sock

      [client]

      socket = /tmp/mysqld.sock

    安装成功后,启动就可以了
