centos 8安装 nginx

哇,我的博客终于在经历db挂掉后回来了,真是太难了,后面具体再来写一次关于db升级的处理吧。今天先写下重装我的环境的心路历程
1. 首先下载安装包

wget http://nginx.org/download/nginx-1.18.0.tar.gz
  1. 解压安装包
tar -zxvf nginx-1.18.0.tar.gz
  1. 进入解压后的安装包
cd nginx-1.18.0
  1. 执行config
./configure \
--user=www \
--group=www \
--prefix=/usr/local/nginx \
--with-http_ssl_module \
--with-http_stub_status_module \
--with-http_realip_module \
--with-threads \
--with-http_v2_module

其中 /usr/local/nginx 是对应的安装目录, www是对应的用户及用户组,我在执行的时候会提示某些软件未安装具体的报错如下

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

这里是需要安装pcre-devel、openssl、openssl-devel这三个依赖,具体命令如下

yum -y install pcre-devel openssl openssl-devel
  1. 接下来就是编译和安装了
make && make isntall
  1. 验证
/usr/local/nginx/sbin/nginx -V

输出如下

nginx version: nginx/1.18.0
built by gcc 8.3.1 20191121 (Red Hat 8.3.1-5) (GCC)
built with OpenSSL 1.1.1c FIPS  28 May 2019 (running with OpenSSL 1.1.1g FIPS  21 Apr 2020)
TLS SNI support enabled
configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --with-threads --with-http_v2_module
  1. 创建软连
ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx
  1. 开机自启动
vim /etc/init.d/nginx 

输入以下内容

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15

make_dirs() {
   # make required directories
   user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*//g' -`
   if [ -z "`grep $user /etc/passwd`" ]; then
       useradd -M -s /bin/nologin $user
   fi
   options=`$nginx -V 2>&1 | grep 'configure arguments:'`
   for opt in $options; do
       if [ `echo $opt | grep '.*-temp-path'` ]; then
           value=`echo $opt | cut -d "=" -f 2`
           if [ ! -d "$value" ]; then
               # echo "creating" $value
               mkdir -p $value && chown -R $user $value
           fi
       fi
   done
}
start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    make_dirs
    echo -n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval
}
stop() {
    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
}
restart() {
    configtest || return $?
    stop
    sleep 1
    start
}
reload() {
    configtest || return $?
    echo -n $"Reloading $prog: "
    killproc $nginx -HUP
    RETVAL=$?
    echo
}
force_reload() {
    restart
}
configtest() {
  $nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
    status $prog
}
rh_status_q() {
    rh_status >/dev/null 2>&1
}
case "$1" in
    start)
        rh_status_q && exit 0
        $1
        ;;
    stop)
        rh_status_q || exit 0

        rh_status_q || exit 7
        $1
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;
    condrestart|try-restart)
        rh_status_q || exit 0
            ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2
esac

授权脚本权限

chmod a+x /etc/init.d/nginx

将nginx服务加入chkcofig管理

chkconfig --add /etc/init.d/nginx
chkconfig nginx on
# 启动
systemctl start nginx
  1. 常用命令
# 启动
systemctl start nginx
# 查看状态
systemctl status nginx
# 停止
systemctl stop nginx

# 重载配置
nginx -s reload
# 测试配置是否正确
nginx -t
  1. 配置路径 /usr/local/nginx/conf

整体的安装就到这里了,下次见
