【轉載】Linux Yum安裝多個MYSQL例項
LINUX作業系統:centOS6.3 64bit(安裝了系統預設開發包) 資料庫一: MYSQL版本:mysql-5.0.56 PORT:3306 系統目錄:/usr/local/mysql3306 資料庫二: MYSQL版本:mysql-5.1.72 PORT:3307 系統目錄:/usr/local/mysql3307
一.安裝開發包(使用預設CENTOS更新源):
複製程式碼程式碼如下:
# 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.關閉iptables和SELINUX
複製程式碼程式碼如下:
# service iptables stop # setenforce 0 # vi /etc/sysconfig/selinux --------------- SELINUX=disabled
--------------- 三.安裝mysql資料庫例項 1.下載編譯包：
複製程式碼程式碼如下:
# 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.安裝前的初始配置工作： 1).建立一個Mysql使用者
複製程式碼程式碼如下:
# useradd mysql
2).新建mysql下data和log子目錄
複製程式碼程式碼如下:
# mkdir /usr/local/mysql{3306,3307}/data # mkdir /usr/local/mysql{3306,3307}/log
3).修改目錄的所屬者以及所屬組許可權
複製程式碼程式碼如下:
# 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).建立mysql相關目錄並配置許可權
複製程式碼程式碼如下:
# 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.解包編譯安裝 編譯資料庫一:
複製程式碼程式碼如下:
# 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
編譯資料庫二:
複製程式碼程式碼如下:
# 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
4.編寫mysql配置項： 資料庫一配置:
複製程式碼程式碼如下:
# 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
------------------------------------------------------- 資料庫二配置:
複製程式碼程式碼如下:
# 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.將mysql的庫檔案路徑加入系統的庫檔案搜尋路徑中 方法一：直接做軟連結
複製程式碼程式碼如下:
# ln -s /usr/local/mysql3306/lib/mysql /usr/lib/mysql
方法二：利用ldconfig匯入系統庫
複製程式碼程式碼如下:
# echo "/usr/local/mysql3306/lib" >> /etc/ld.so.conf.d/mysql.conf # ldconfig
6.輸出mysql的標頭檔案到系統標頭檔案
複製程式碼程式碼如下:
# ln -s /usr/local/mysql3306/include/mysql /usr/include/mysql
注: 此處只需將一個mysql例項的庫檔案新增到系統庫,無需多次新增
7.進入相應例項的安裝路徑,初始化各自配置指令碼 資料庫一配置:
複製程式碼程式碼如下:
# cd /usr/local/mysql3306 # scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql3306/data
資料庫二配置:
複製程式碼程式碼如下:
# cd /usr/local/mysql3307 # scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql3307/data
8.複製mysql啟動指令碼到系統服務目錄,並更改指令碼配置
複製程式碼程式碼如下:
# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld3306 # cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld3307
資料庫一配置:
複製程式碼程式碼如下:
# vi /etc/init.d/mysqld3006
搜尋如下行,紅色標註的為新增的引數: ---------------------------------------------
複製程式碼程式碼如下:
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 & --------------------------------------------
資料庫二配置:
複製程式碼程式碼如下:
# vi /etc/init.d/mysqld3007
搜尋如下行,紅色標註的為新增的引數: ---------------------------------------------
複製程式碼程式碼如下:
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 $other_args >/dev/null 2>&1 & --------------------------------------------
9.系統啟動項相關配置 資料庫一配置:
複製程式碼程式碼如下:
# chkconfig --add mysqld3306 #新增開機啟動服務 # chkconfig --level 35 mysqld3306 on #設定mysql啟動
資料庫二配置:
複製程式碼程式碼如下:
# chkconfig --add mysqld3307 # chkconfig --level 35 mysqld3307 on
10.啟動mysql 資料庫一啟動:
複製程式碼程式碼如下:
# service mysqld3306 start
資料庫二啟動:
複製程式碼程式碼如下:
# service mysqld3307 start
11 新增mysql命令集到系統全域性變數 注:如果系統之前未安裝mysql客戶端,可以將編譯好的mysql命令集匯入系統全域性變數 以後就可以直接使用mysql命令集,而不需要使用絕對路徑訪問.
複製程式碼程式碼如下:
# echo "PATH=$PATH:/usr/local/mysql3306/bin;export PATH" >> /etc/profile # source /etc/profile
12. 設定初始賬戶,並登陸後臺: 資料庫一:
複製程式碼程式碼如下:
# /usr/local/mysql3306/bin/mysqladmin -u root password 123456 #設定超級管理員密碼 # /usr/local/mysql3306/bin/mysql -P3306 -S/tmp/mysql3306.sock -uroot -p123456 #連線資料庫
資料庫二: # /usr/local/mysql3307/bin/mysqladmin -u root password 123456 #設定超級管理員密碼 # /usr/local/mysql3307/bin/mysql -P3307 -S/tmp/mysql3307.sock -uroot -p123456 #連線資料庫
注: 因為加了mysql環境變數,以後系統後臺可以直接使用mysql命令登入,這裡使用絕對路徑是為了規範操作 # mysql -P3307 -S/tmp/mysql3307.sock -uroot -p123456
13.埠測試:
複製程式碼程式碼如下:
#lsof -i:3306 #lsof -i:3307
OK,大功告成!
