Centos中安装多个mysql数据的配置实例 |
|
本文标签：Centos安装多个mysql 注:本文档做了两个MYSQL实例,多个实例方法以此类推 LINUX操作系统:centOS6.3 64bit(安装了系统默认开发包) 一.安装开发包(使用默认CENTOS更新源): 复制代码 代码如下: # yum -y install wget gcc-c++ ncurses ncurses-devel cmake make perl bison openssl openssl-devel gcc* libxml2 libxml2-devel curl-devel libjpeg* libpng* freetype* 二.关闭iptables和SELINUX 复制代码 代码如下: # service iptables stop # setenforce 0 # vi /etc/sysconfig/selinux --------------- SELINUX=disabled --------------- 三.安装mysql数据库实例 1.下载编译包： 复制代码 代码如下: # su - # mkdir '/src # cd src # wget http://mysql.cdpa.nsysu.edu.tw/Downloads/MySQL-5.1/mysql-5.1.73.tar.gz # wget http://down1.chinaunix.net/distfiles/mysql-5.0.56.tar.gz 2.安装前的初始配置工作： 1).创建一个Mysql用户 复制代码 代码如下: # useradd mysql 2).新建mysql下data和log子目录 复制代码 代码如下: # mkdir /usr/local/mysql{3306,3307}/data # mkdir /usr/local/mysql{3306,3307}/log 3).修改目录的所属者以及所属组权限 复制代码 代码如下: # chown -R mysql:mysql /usr/local/mysql{3306,3307}/data/ # chown -R mysql:mysql /usr/local/mysql{3306,3307}/log/ # chmod 750 /usr/local/mysql{3306,3307}/data # chmod 750 /usr/local/mysql{3306,3307}/log 4).创建mysql相关目录并配置权限 复制代码 代码如下: # mkdir -p /usr/local/mysql{3306,3307}/etc # chown -R mysql.mysql /usr/local/mysql{3306,3307}/etc # mkdir -p /var/run/mysqld{3306,3307} # chown -R mysql.mysql /var/run/mysqld{3306,3307} # mkdir -p /var/lib/mysqld{3306,3307} # chown -R mysql.mysql /var/lib/mysqld{3306,3307} # cp /etc/my.cnf /usr/local/mysql{3306,3307}/etc 3.解包编译安装 编译数据库一: 复制代码 代码如下: # cd '/src # tar -zxvf mysql-5.0.56.tar.gz # cd mysql-5.0.56 ./configure --prefix=/usr/local/mysql3306 --with-mysqld-user=mysql --sysconfdir=/usr/local/mysql3306/etc --localstatedir=/usr/local/mysql3306/data --with-tcp-port=3306 -enable-assembler --with-mysqld-ldflags=-all-static --with-charset=utf8 --with-extra-charsets=gbk -with-extra-charsets=all --with-plugins=csv,innobase,myisam,heap --with-unix-socket-path=/tmp/mysql3306.sock # make # make install 编译数据库二: 复制代码 代码如下: # cd '/src
# tar -zxvf mysql-5.1.71.tar.gz # cd mysql-5.1.71 ./configure --prefix=/usr/local/mysql3307 --with-mysqld-user=mysql --sysconfdir=/usr/local/mysql3307/etc --localstatedir=/usr/local/mysql3307/data --with-tcp-port=3307 -enable-assembler --with-mysqld-ldflags=-all-static --with-charset=utf8 --with-extra-charsets=gbk -with-extra-charsets=all --with-plugins=csv,innobase,myisam,heap --with-unix-socket-path=/tmp/mysql3307.sock # make # make install
复制代码 代码如下: # vi /usr/local/mysql3306/etc/my.cnf ------------------------------------------------------- [mysqld] datadir=/usr/local/mysql3306/data socket=/tmp/mysql3306.sock user=mysql port=3306 pid-file=/var/lib/mysqld3306/mysql.pid # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 max_connections= 16384 skip-name-resolve skip-locking key_buffer = 256M max_allowed_packet = 32M table_cache = 3072 thread_cache_size = 256 sort_buffer_size = 16M read_buffer_size = 4M read_rnd_buffer_size = 16M net_buffer_length = 256M thread_stack = 8M query_cache_size = 128M query_cache_limit = 2M wait_timeout=7200 interactive_timeout=7200 #log log-error=/usr/local/mysql3306/log/error.log log=/usr/local/mysql3306/log/mysql.log long_query_time=2 log-slow-queries= /usr/local/mysql3306/log/slowquery.log log-bin= /usr/local/mysql3306/log/bin.log expire_logs_days = 15 sync_binlog = 1 max_binlog_cache_size = 4294967295 local-infile=0 [mysqld_safe] log-error=/var/log/mysqld3306.log pid-file=/var/run/mysqld3306/mysqld.pid ------------------------------------------------------- 数据库二配置: 复制代码 代码如下: # vi /usr/local/mysql3307/etc/my.cnf
------------------------------------------------------- [mysqld] datadir=/usr/local/mysql3307/data socket=/tmp/mysql3307.sock user=mysql port=3307 pid-file=/var/lib/mysqld3307/mysql.pid # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 max_connections= 16384 skip-name-resolve skip-locking key_buffer = 256M max_allowed_packet = 32M table_cache = 3072 thread_cache_size = 256 sort_buffer_size = 16M read_buffer_size = 4M read_rnd_buffer_size = 16M net_buffer_length = 256M thread_stack = 8M query_cache_size = 128M query_cache_limit = 2M wait_timeout=7200 interactive_timeout=7200 #log log-error=/usr/local/mysql3307/log/error.log log=/usr/local/mysql3307/log/mysql.log long_query_time=2 log-slow-queries= /usr/local/mysql3307/log/slowquery.log log-bin= /usr/local/mysql3307/log/bin.log expire_logs_days = 15 sync_binlog = 1 max_binlog_cache_size = 4294967295 local-infile=0 [mysqld_safe] log-error=/var/log/mysqld3307.log pid-file=/var/run/mysqld3307/mysqld.pid ------------------------------------------------------- 5.将mysql的库文件路径加入系统的库文件搜索路径中 复制代码 代码如下: # ln -s /usr/local/mysql3306/lib/mysql /usr/lib/mysql 方法二：利用ldconfig导入系统库 复制代码 代码如下: # echo "/usr/local/mysql3306/lib" >> /etc/ld.so.conf.d/mysql.conf # ldconfig 6.输出mysql的头文件到系统头文件 复制代码 代码如下: # ln -s /usr/local/mysql3306/include/mysql /usr/include/mysql 注: 此处只需将一个mysql实例的库文件添加到系统库,无需多次添加 7.进入相应实例的安装路径,初始化各自配置脚本 复制代码 代码如下: # cd /usr/local/mysql3306 # scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql3306/data 数据库二配置: 复制代码 代码如下: # cd /usr/local/mysql3307 # scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql3307/data 8.复制mysql启动脚本到系统服务目录,并更改脚本配置 复制代码 代码如下: # cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld3306 # cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld3307 数据库一配置: 复制代码 代码如下: # vi /etc/init.d/mysqld3006 搜索如下行,红色标注的为添加的参数: --------------------------------------------- 复制代码 代码如下: basedir=/usr/local/mysql3306 datadir=/usr/local/mysql3306/data conf=/usr/local/mysql3306/etc/my.cnf $bindir/mysqld_safe --defaults-file=$conf --datadir=$datadir --pid-file=$server_pid_file $other_args >/dev/null 2>&1 & -------------------------------------------- 数据库二配置: 复制代码 代码如下: # vi /etc/init.d/mysqld3007 搜索如下行,红色标注的为添加的参数: --------------------------------------------- 复制代码 代码如下: basedir=/usr/local/mysql3307
datadir=/usr/local/mysql3307/data conf=/usr/local/mysql3307/etc/my.cnf $bindir/mysqld_safe --defaults-file=$conf --datadir=$datadir --pid-file=$server_pid_file $other_args >/dev/null 2>&1 & --------------------------------------------
复制代码 代码如下: # chkconfig --add mysqld3306 #添加开机启动服务 # chkconfig --level 35 mysqld3306 on #设置mysql启动 数据库二配置: 复制代码 代码如下: # chkconfig --add mysqld3307 # chkconfig --level 35 mysqld3307 on 10.启动mysql 数据库一启动: 复制代码 代码如下: # service mysqld3306 start 数据库二启动: 复制代码 代码如下: # service mysqld3307 start 11 添加mysql命令集到系统全局变量 注:如果系统之前未安装mysql客户端,可以将编译好的mysql命令集导入系统全局变量 以后就可以直接使用mysql命令集,而不需要使用绝对路径访问. 复制代码 代码如下: # echo "PATH=$PATH:/usr/local/mysql3306/bin;export PATH" >> /etc/profile # source /etc/profile 12. 设置初始账户,并登陆后台: 数据库一: 复制代码 代码如下: # /usr/local/mysql3306/bin/mysqladmin -u root password 123456 #设置超级管理员密码
# /usr/local/mysql3306/bin/mysql -P3306 -S/tmp/mysql3306.sock -uroot -p123456 #连接数据库 数据库二: 注: 因为加了mysql环境变量,以后系统后台可以直接使用mysql命令登录,这里使用绝对路径是为了规范操作 13.端口测试: 复制代码 代码如下: #lsof -i:3306
#lsof -i:3307 OK,大功告成! |
