部署编译安装的nginx-CFANZ编程社区

1.编写systemd配置文件

先看看官方nginx的systemd配置文件

vim /usr/lib/systemd/system/nginx.service          #yum安装的nginx配置文件目录

[Unit]
Description=nginx - high performance web server
Documentation=http://nginx.org/en/docs/
After=network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target

[Service]
Type=forking
PIDFile=/var/run/nginx.pid
ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf
ExecReload=/bin/sh -c "/bin/kill -s HUP $(/bin/cat /var/run/nginx.pid)"
ExecStop=/bin/sh -c "/bin/kill -s TERM $(/bin/cat /var/run/nginx.pid)"

[Install]
WantedBy=multi-user.target

拷贝一份改名为nginx2.service

cp /usr/lib/systemd/system/nginx.service /usr/lib/systemd/system/nginx2.service

修改nginx2.service配置文件

[Unit]
Description=nginx - high performance web server
Documentation=http://nginx.org/en/docs/
After=network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target

[Service]
Type=forking
PIDFile= /tmp/nginx/pid/nginx.pid      #PID路径修改为编译安装的路径（需要在nginx目录下创建一个pid目录）
ExecStart=/tmp/nginx/sbin/nginx -c /opt/nginx/conf/nginx.conf       #启动选项使用编译包中的启动
ExecReload=/bin/sh -c "/bin/kill -s HUP $(/bin/cat /tmp/nginx/pid/nginx.pid)"    #修改路径
ExecStop=/bin/sh -c "/bin/kill -s TERM $(/bin/cat /tmp/nginx/pid/nginx.pid)"     #修改路径

[Install]
WantedBy=multi-user.target

2.修改nginx配置文件

vim /tmp/nginx/conf/nginx.conf     #打开编译安装的nginx配置文件

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

pid        /tmp/nginx/pid/nginx.pid;    #将pid注释取消，指定路径


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

3.启动nginx服务

systemctl daemon-reload            #重载systemd配置文件
systemctl start nginx2.service     #启动编译安装的nginx

启动服务时出现报错，提示80端口被占用

[root@Centos7-100 tmp]# systemctl status nginx2.service
● nginx2.service - nginx - high performance web server
   Loaded: loaded (/usr/lib/systemd/system/nginx2.service; disabled; vendor preset: disabled)

修改编译安装nginx配置文件中的端口

 #gzip  on;

    server {
        listen       8080;        #默认为80，修改为8080端口
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;

            index  index.html index.htm;
        }

重启一下nginx2

[root@Centos7-100 tmp]#  systemctl start nginx2
[root@Centos7-100 tmp]#

查看一下服务状态

[root@Centos7-100 tmp]# systemctl status nginx2
