本篇內(nèi)容介紹了“Linux下MySQL的多實(shí)例部署及安裝指南”的有關(guān)知識(shí),在實(shí)際案例的操作過(guò)程中,不少人都會(huì)遇到這樣的困境,接下來(lái)就讓小編帶領(lǐng)大家學(xué)習(xí)一下如何處理這些情況吧!希望大家仔細(xì)閱讀,能夠?qū)W有所成!
簡(jiǎn)單地說(shuō),Mysql多實(shí)例就是在一臺(tái)服務(wù)器上同時(shí)開啟多個(gè)不同的服務(wù)端口(3306、3307),同時(shí)運(yùn)行多個(gè)Mysql服務(wù)進(jìn)程,這些服務(wù)進(jìn)程通過(guò)不同的socket監(jiān)聽不同的服務(wù)端口來(lái)提供服務(wù)。
這些Mysql多實(shí)例公用一套Mysql安裝程序,使用不同的my.cnf(也可以相同)配置文件,啟動(dòng)程序(也可以相同)和數(shù)據(jù)文件。在提供服務(wù)時(shí),多實(shí)例 Mysql在邏輯上看來(lái)是各自獨(dú)立的,它們根據(jù)配置文件的對(duì)應(yīng)設(shè)定值,獲得服務(wù)器相應(yīng)數(shù)量的硬件資源。
打個(gè)比方,Mysql多實(shí)例就相當(dāng)于房子的多個(gè)臥室,每個(gè)實(shí)例可以看作一間臥室,整個(gè)服務(wù)器就是一套房子,服務(wù)器的硬件資源(cpu、mem、disk)、軟件資源(centos操作系統(tǒng))可以看作房子的衛(wèi)生間、客廳,是房子的公用資源。
1、有效利用服務(wù)器資源:當(dāng)單個(gè)服務(wù)器資源有空剩余時(shí),可以充分利用剩余的資源創(chuàng)建更多的MySQL實(shí)例提供更多的服務(wù)。2、節(jié)約服務(wù)器資源:當(dāng)公司資金緊張,但是數(shù)據(jù)庫(kù)又需要多個(gè)并且需各自盡量獨(dú)立提供服務(wù)或者需要主從同步等,MySQL多實(shí)例就再好不過(guò)了。
3、資源相互爭(zhēng)搶問(wèn)題:當(dāng)某個(gè)服務(wù)實(shí)例并發(fā)很高或者有慢查詢時(shí),整個(gè)實(shí)例會(huì)消耗更多的內(nèi)存、CPU、磁盤、IO資源,導(dǎo)致服務(wù)器上的其它實(shí)例提供服務(wù)的質(zhì)量下降,這就相當(dāng)于大家在一個(gè)房子的不同臥室(MySQL實(shí)例),需要上廁所(硬件的CPU、內(nèi)存、磁盤的IO資源)時(shí),一個(gè)占用了廁所,其他人都要等待。
具體詳細(xì)參考官網(wǎng) (https://dev.mysql.com/doc/refman/5.7/en/installing.html)
mysql的安裝方法有多種,如二進(jìn)制安裝、源碼編譯安裝、yum安裝;
yum安裝都是默認(rèn)路徑,安裝相對(duì)簡(jiǎn)單;
源碼安裝編譯的過(guò)程比較長(zhǎng),若沒(méi)有對(duì)源碼進(jìn)行修改且要求使用mysql較高版本;
準(zhǔn)備環(huán)境。
