 本次主要是mysql-5.5.54 的安裝

基礎(chǔ)環(huán)境為：

                  centos 6.8 

 一、下載mysql-5.5.54 安裝包

    創(chuàng)建軟件存放目錄

                    mkdir /home/softwares/

                    cd  /home/softwares/

          wget  http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.54.tar.gz

二、安裝mysql 依賴包

                    yum install -y cmake;

                    yum install -y gcc gcc-c++ ;

                    yum install -y ncurses-devel.x86_64 ;

                    yum install -y cmake.x86_64 ;

                    yum install -y libaio.x86_64 ;

                    yum install -y bison.x86_64 ;

                    yum install -y gcc-c++.x86_64;

                    yum install -y perl-Module-Build;

                    yum install -y libtool zilib-devel ;

                    yum install -y libaio.x86_64;

                    yum install -y perl.x86_64;

                    yum install -y perl-Module-Pluggable.x86_64;

                    yum install -y perl-Pod-Escapes.x86_64;

                    yum install -y perl-Pod-Simple.x86_64;

                    yum install -y perl-libs.x86_64;

                    yum install -y perl-version.x86_64 ;

                    yum install –y openssl openssl-devel ncurses ncurses-devel;

            2、創(chuàng)建用戶和組分區(qū)

                  groupadd mysql

                 useradd mysql -g mysql -M -s /sbin/nologin

            3、解壓mysql-5.5.54.tar.gz

                  tar -zxvf mysql-5.5.54.tar.gz && cd mysql-5.5.54/  && chmod +x *

            4、編譯安裝

cmake \ ##相當(dāng)于config -DCMAKE_INSTALL_PREFIX=/u01/app/mysql/db \  ##數(shù)據(jù)庫安裝的目錄 -DSYSCONFDIR=/u01/app/mysql/db/etc \    ##數(shù)據(jù)庫安裝的配置文件，不用原來的默認(rèn)文件可以避免多次升級的時候讀取錯誤的配置文件 -DMYSQL_DATADIR=/u01/data/mysql/db/data \ ##數(shù)據(jù)庫默認(rèn)存放庫表存放的位置 -DWITH_MYISAM_STORAGE_ENGINE=1 \  -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_MEMORY_STORAGE_ENGINE=1 \ -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \ -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \ -DWITH_READLINE=1 \ -DMYSQL_UNIX_ADDR=/u01/app/mysql/db/mysql.sock \ ##本地通信日志 -DMYSQL_TCP_PORT=3306 \ -DENABLED_LOCAL_INFILE=1 \ -DWITH_PARTITION_STORAGE_ENGINE=1 \ -DEXTRA_CHARSETS=all \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \

       make  install

          5、編寫配置文件

         cd /u01/app/mysql/db/  &&  mkdir etc && cd etc

              mkdir etc

                vi my.cnf

cat my.cnf [mysqld] #########data########### user=mysql basedir = /u01/app/mysql/db datadir = /u01/app/mysql/data innodb_log_group_home_dir=/u01/app/mysql/engine/innolog innodb_log_file_size = 50M innodb_data_home_dir=/u01/app/mysql/engine/innodata #innodb_data_file_path = ibdata1:100M;ibdata2:150M:autoextend innodb_data_file_path = ibdata1:100M:autoextend log-bin = /u01/app/mysql/log/mysql-binlog log-bin-index = /u01/app/mysql/log/mysql-bin.index binlog_cache_size = 32M max_binlog_size=512M binlog_format=row innodb_file_per_table=1 log-error = /u01/app/mysql/mysql-error.log pid-file = /u01/app/mysql/mysql.pid skip-name-resolve socket=/u01/app/mysql/mysql.sock ############pool######### #*******skip-innodb********* innodb_additional_mem_pool_size = 64M innodb_buffer_pool_size=256M innodb_write_io_threads = 8 innodb_read_io_threads = 8 innodb_thread_concurrency = 16 innodb_flush_log_at_trx_commit = 1 innodb_log_buffer_size = 16M innodb_log_file_size = 512M innodb_log_files_in_group = 3 innodb_max_dirty_pages_pct = 90 innodb_lock_wait_timeout = 120 port=3306 server-id= 1 # *** global cache *** read_buffer_size = 32M read_rnd_buffer_size = 128M sort_buffer_size = 64M join_buffer_size = 64M # *** query cache *** query_cache_size = 128M query_cache_limit = 4M # *** bin log *** #log_slave_updates log_warnings ###########others######### #***transaction*** default-storage-engine = INNODB transaction_isolation = REPEATABLE-READ # *** thread *** thread_cache_size = 16 thread_stack = 512K #*** network *** back_log = 512 #skip-networking max_connections = 3000 max_connect_errors = 30 table_open_cache = 4096 max_allowed_packet = 32M max_heap_table_size = 512M #*** char set *** character-set-server = utf8 #explicit_defaults_for_timestamp = true # *** tmp table *** tmp_table_size = 128M # *** slow query log *** slow_query_log long_query_time = 10 [mysqldump] quick max_allowed_packet = 32M [mysql] auto-rehash [myisamchk] key_buffer_size = 12M sort_buffer_size = 12M read_buffer = 32M write_buffer = 32M [mysqlhotcopy] interactive-timeout [client] socket=/u01/app/mysql/mysql.sock port=3306

          6、將mysql啟動腳本腳本命令復(fù)制到/etc/init.d/

                cp /u01/app/mysql/db/support-files/mysql.server /etc/init.d/mysqld && chmod +x                 /etc/init.d/mysqld

                chmod +x /etc/init.d/mysqld

      7、根據(jù)my.cnf 創(chuàng)建目錄他不會自動創(chuàng)建目錄

             mkdir -p /u01/app/mysql/data/engine/innolog

        mkdir -p /u01/app/mysql/data/engine/innodata

               mkdir -p /u01/app/mysql/data/mysql-binlog

              mkdir -p /u01/app/mysql/log/

               chown mysql. /u01/app/mysql/ -R

                cd /u01/app/mysql/db

         8、初始化語句數(shù)據(jù)庫安裝指定的目錄，數(shù)據(jù)庫默認(rèn)存放目錄

            ./scripts/mysql_install_db --basedir=/u01/app/mysql/db --datadir=/u01/app/mysql/data --user=mysql

          更改環(huán)境變量

            vim ~/.bash_profile

            PATH=$PATH:$HOME/bin:/u01/app/mysql/db/bin/

            環(huán)境變量生效

             source ~/.bash_profile

            如果報錯：

 /etc/init.d/mysqld start

 配置文件的問題

 Starting MySQL... ERROR! The server quit without updating PID file (/data/mysql/mysql.pid).

一般需要自己查詢配置文件是否設(shè)置的參數(shù)過大或者過小，查看機器內(nèi)存是否過小，如果都是可以的請刪除除了db 文件之外的所有 然后重新創(chuàng)建目錄

             ##########啟動成功之后設(shè)置密碼###########

                mysqladmin -uroot password "123456"
