安裝nginx 關閉防火牆和selinux
[[email protected] ~]# systemctl stop firewalld
[[email protected] ~]# setenforce 0
建立系統使用者
[[email protected] ~]# useradd -r -M -s /sbin/nologin nginx
安裝依賴環境
#需用網路源安裝依賴包。
[[email protected] ~]# yum -y install pcre-devel openssl openssl-devel gd-devel gcc gcc-c++
[ 建立日誌存放目錄
[[email protected] ~]# mkdir -p /var/log/nginx
[[email protected] ~]# chown -R nginx.nginx /var/log/nginx
下載nginx，編譯安裝
[[email protected] ~]# cd /usr/src/
[[email protected] src]# wget http://nginx.org/download/nginx-1.12.0.tar.gz
[ 啟動nginx
#配置環境變數
[[email protected] ~]# echo 'export PATH=/usr/local/nginx/sbin:$PATH' > /etc/pr

#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
#新增下面4行，配置負載均衡
