運(yùn)維 keepalived實(shí)現(xiàn)nginx高可用以及腦裂的解決 nginx實(shí)現(xiàn)高性能用到的關(guān)鍵技術(shù)

要實(shí)現(xiàn)Nginx的高可用和腦裂的解決，可以使用keepalived來實(shí)現(xiàn)。以下是具體的步驟：

  1. 安裝keepalived：在服務(wù)器上安裝keepalived，可以通過yum或apt-get命令進(jìn)行安裝。

  2. 配置keepalived：編輯keepalived配置文件，通常位于/etc/keepalived/keepalived.conf。在該文件中，需要設(shè)置以下參數(shù)：

    • virtual_router_id：虛擬路由器ID，用于區(qū)分不同的虛擬路由。
    • virtual_ipaddress：虛擬IP地址，用于區(qū)分不同的虛擬網(wǎng)絡(luò)。
    • virtual_server：虛擬服務(wù)器，用于區(qū)分不同的虛擬服務(wù)。
    • virtual_server_name：虛擬服務(wù)器名稱，用于標(biāo)識不同的虛擬服務(wù)。
    • virtual_server_port：虛擬服務(wù)器端口，用于標(biāo)識不同的虛擬服務(wù)。
    • virtual_server_protocol：虛擬服務(wù)器協(xié)議，用于標(biāo)識不同的虛擬服務(wù)。

  3. 創(chuàng)建虛擬路由器：在keepalived配置文件中，添加以下內(nèi)容：

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    priority 100
