2.ansible相关配置

cat /etc/ansible/hosts [webserver] 192.168.1.101 192.168.1.102

3.在/etc/ansible/roles中创建nginx目录结构

[root@Centos roles]# mkdir -p/etc/ansible/roles/nginx/{defaults,files,handlers,meta,tasks,templates,vars}

整体目录结构:

Ansible自动化安装nginx

install_nginx.sh内容：

#!/bin/bash # yum -y install gcc openssl-devel pcre-devel zlib-devel groupadd -r nginx useradd -r -g nginx -s /bin/false -M nginx cd /root/soft && tar zxf nginx-1.2.2.tar.gz && cd nginx-1.2.2 && ./configure \ --prefix=/usr/local/nginx \ --sbin-path=/usr/sbin/nginx \ --conf-path=/etc/nginx/nginx.conf \ --error-log-path=/var/log/nginx/error.log \ --http-log-path=/var/log/nginx/access.log \ --pid-path=/var/run/nginx/nginx.pid \ --lock-path=/var/lock/nginx.lock \ --user=nginx \ --group=nginx \ --with-http_ssl_module \ --with-http_flv_module \ --with-http_stub_status_module \ --with-http_gzip_static_module \ --http-client-body-temp-path=/var/tmp/nginx/client/ \ --http-proxy-temp-path=/var/tmp/nginx/proxy/ \ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \ --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \ --http-scgi-temp-path=/var/tmp/nginx/scgi \ --with-pcre make && make install

main.yml内容:

- name: copy nginx-1.2.2.tar.gz to webservers copy: src=nginx-1.2.2.tar.gz dest=/root/soft/nginx-1.2.2.tar.gz - name: copy install_nginx.sh to webservers copy: src=install_nginx.sh dest=/root/soft/install_nginx.sh - name: install nginx shell: /bin/bash /root/soft/install_nginx.sh

webservice.yml内容:

- hosts: webserver remote_user: root roles: - nginx

4.执行ansible-playbook进行安装:

[root@Centos files]# cd /etc/ansible/ [root@Centos ansible]# ls ansible.cfg hosts roles webservice.yml [root@Centos ansible]# ansible-playbook webservice.yml

安装成功!

5.测试

由于webserver两个节点安装完没有启动脚本，我们从ansible主机上拷贝一下启动脚本：

[root@Centos ansible]# scp /etc/rc.d/init.d/nginx root@192.168.1.101:/etc/rc.d/init.d/ [root@Centos ansible]# scp /etc/rc.d/init.d/nginx root@192.168.1.102:/etc/rc.d/init.d/

以下为脚本内容:

#!/bin/sh # # nginx - this script starts and stops the nginx daemon # # chkconfig: - 85 15 # description: Nginx is an HTTP(S) server, HTTP(S) reverse \ # proxy and IMAP/POP3 proxy server # processname: nginx # config: /etc/nginx/nginx.conf # config: /etc/sysconfig/nginx # pidfile: /var/run/nginx.pid # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. [ "$NETWORKING" = "no" ] && exit 0 nginx="/usr/local/nginx/sbin/nginx" prog=$(basename $nginx) NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf" [ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx lockfile=/var/lock/subsys/nginx make_dirs() { # make required directories user=`nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=$[^ ]*$.*/\1/g' -` options=`$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 $1 ;; restart|configtest) $1 ;; reload) 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
