MySQL编译安装_mysql编译csdn

MySQL的安装有三种方式
1.RPM安装MySQL
2.yum源的安装方式
在本篇文章中，不对上述的两种安装方式进行过多的阐述，对第三种安装方式进行详细的介绍
3.源代码编译安装
参考文档：https://github.com/Hackeruncle/MySQL/blob/master/MySQL%205.6.23%20Install.txt

1.下载(root用户下进行操作)

    将mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz安装到/usr/local目录下
        $>cd /usr/local
        $>wget https://downloads.mariadb.com/archives/mysql-5.6/mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz

2.检查是否安装过mysql(root用户下进行操作)

    查看是否有mysql进程
        $>ps -ef | grep mysqld
    查看是否有mysql的rpm包
        $>rpm -qa | grep -i mysql

3.解压并移动(root用户下进行操作)

    $>tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
    $>mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql

4.创建一个用户组和用户(root用户下进行操作)

    创建一个组(-g指定组ID)
        $>groupadd -g 101 dba
    创建一个用户(-u指定用户ID -G表示属于哪个组 -d表示创建的家目录在哪里)
        $>useradd -u 514 -g dba -G root -d /opt/app/mysql mysqladmin
    查看mysqladmin用户
        $>id mysqladmin
          uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
    为mysqladmin用户设置密码(密码为mysql  注意这里的mysqladmin密码为Linux系统用户的密码非mysql数据库的登陆用户的密码)
        $>passwd mysqladmin

5.编辑文件/etc/my.cnf(root用户下进行操作)
MySQL默认启动过程: /etc/my.cnf->/etc/mysql/my.cnf->SYSCONFDIR/my.cnf->$MYSQL_HOME/my.cnf-> –defaults-extra-file->~/my.cnf

    $>vi /etc/my.cnf
        将下面内容复制进去(修改一个地方)
        [client]
        port            = 3306
        socket          = /opt/app/mysql/data/mysql.sock

6.改变/etc/my.cnf和/opt/app/mysql的所属组和用户以及权限(在root用户下进行操作)

    改变/etc/my.cnf的所属组和用户
        $>chown  mysqladmin:dba /etc/my.cnf
    授予640权限
        $>chmod  640 /etc/my.cnf  
        $>ll my.cnf
          -rw-r----- 1 mysqladmin dba 2201 Aug 25 23:09 my.cnf
    改变/opt/app/mysql/mysql的所属组和用户
        $>chown -R mysqladmin:dba /opt/app/mysql
    授予755权限
        $>chmod -R 755 /opt/app/mysql

7.执行命令，进行mysql的安装(mysqladmin用户下进行操作)
注意：必须切换成mysqladmin用户来启动MySQL，如果使用root用户会报错

    $>su - mysqladmin 
    $>pwd
      /opt/app/mysql
    创建目录arch(重要)
        $>cd /opt/app/mysql
        $>>mkdir arch
    按照脚本进行安装(重要)
        $>scripts/mysql_install_db  --user=mysqladmin --basedir=/opt/app/mysql --datadir=/opt/app/mysql/data

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 #缺少libaio.so 包
开始排错：

1.查看版本
$>cat /proc/version
Linux version 2.6.18-164.11.1.el5 (mockbuild@builder10.centos.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-46)) #1 SMP Wed Jan 20 07:32:21 EST 2010
 2.$>rpm -qa |grep gcc
  libgcc-4.1.2-46.el5_4.2
  libgcc-4.1.2-46.el5_4.2
 3.使用root用户进行安装
$>yum -y install libaio

8.再次进行安装(mysqladmin用户下进行操作)

    安装的过程中，指定user、basedir、datadir
        $>scripts/mysql_install_db  --user=mysqladmin --basedir=/opt/app/mysql --datadir=/opt/app/mysql/data

9.确认mysql服务(root用户下进行操作)

    切换目录到/opt/app/mysql
        $>cd /opt/app/mysql
    将服务文件拷贝到init.d下，并重命名为mysql
        $>cp support-files/mysql.server /etc/rc.d/init.d/mysql 
    赋予可执行权限
        $>chmod +x /etc/rc.d/init.d/mysql
    删除服务
        $>chkconfig --del mysql
    添加服务
        $>chkconfig --add mysql
        $>chkconfig --level 345 mysql on

9.启动mysql服务，查看进程(mysqladmin用户下进行操作)

    切换到mysqladmin用户
        $>su - mysqladmin
        $>pwd
          /usr/local/mysql
    删除my.cnf文件
        $>rm -rf my.cnf
    启动
        $>bin/mysqld_safe &
    查看mysql的相关进程
        $>ps -ef | grep mysqld
    查看mysql端口及状态
        $>netstat -tulnp | grep mysql
    查看mysql进程的状态
        $>service mysql status

见下图：

10.登陆到mysql

    $>mysql

登陆成功：

11.编译过程中的其它问题
切换用户显示-bash-4.1$的解决办法
将mysqladmin的环境变量拷贝至/opt/app/mysql目录下

            $>cp -r /etc/skel/.* /opt/app/mysql
